Need an image size reducer?
This image resize tool changes a photo's width and height, or knocks it down to a percentage of what it was. Proportions stay locked unless you unlock them, and it all happens in your browser.

You get the real result, not a blurry preview. Free means the full-size restored photo — the same file a paid tool would sell you.
A resize tool and a resizer image both open this page: drop a file in, set a width or a percentage, and download.
A resize image windows question gets the same browser page as any other device — it's not a separate program. Resize image windows 11 needs no special version. Resize image mac and resize image chromebook use that identical page too, since nothing here is platform-specific. There's no resize image exe to download. It isn't resize image ai in the way the AI tools elsewhere on this site are — resizing just scales pixels with the same maths regardless of browser, which is also why resize image ai without losing quality has a real limit: shrinking loses nothing, but enlarging past the original size needs the separate upscaler tool instead. Resize image android runs the same way too.
Type an exact width if you have been given one — 1080 px for an Instagram post, 512 px for an app icon, 800 px for a blog image. Leave "keep the proportions" ticked and the height follows on its own, so the photo never comes out stretched. If you genuinely need a fixed width and height that do not match the original shape, untick it and accept the squash, or crop to the right shape first, which is what you almost always actually want.
If you are just trying to make a file lighter, think in percentages instead. Halving the width leaves a quarter of the pixels, which is a far bigger saving than any quality setting will give you. The same width-or-percent choice applies whether it's for the web or for print.
Plenty of people search for resizing an image "in KB", and that is worth untangling, because the two knobs do different jobs. Pixels are how big the picture is. Kilobytes are how heavy the file is. Making the pixels smaller does make the file lighter, but you cannot aim at a KB number by dragging a width around — you would be guessing and re-exporting all afternoon.
So if the requirement is a file size, use the compress page, which takes a KB target and works the settings out for you. Use this page when the requirement is a dimension. And when a form demands both, do it in that order: resize to the dimension here, then compress to the size there.
Most resizing is somebody else's rule, not a preference. These are the ones that come up over and over, and none of them need a photo editor — just a quick way to change image size to an exact number of pixels.
Making a photo bigger is a different job. Stretching pixels up in a browser just makes them softer; rebuilding the missing detail needs a model, which is what the upscaler on this site is for.
Whatever term brought you here — image resizer, photo resizer or picture resizer — it's the same tool underneath: drop a file in, set a width or a percentage, and download. Looking for an online image resizer you can use straight from a phone browser without installing anything? This works exactly the same way there, no app required. You can just as easily resize photo online here if that's the phrase you searched for — same tool, only the label differs. Search engines don't care whether you type resize images online or resize image online either; both land on this same uploader.
This is also a free image resizer online in the same sense as everything else on the page: no account, no watermark, and the full-size file every time. If what you need is a way to resize image for free, an image resizer free of any sign-up wall, or a free photo resizer for a stack of old snapshots, that's exactly what's running here. It works the same regardless of the file type: a jpg resize, a png resize and a webp resize all take the same width-or-percentage step.
Online resize image needs no install, and photo resize online works the same way: drop the file in, type a width, and download. The same goes for cost. Image resize free describes exactly this page: no watermark, no account, either way. Free resize image runs entirely in your browser, keeps proportions, and never uploads the file: pick a width or a percentage and PicReviver does the math and the resize locally, with no daily cap on how many times you can use it. Resize picture online free adds "online" but changes nothing about the result. Image resize online just means it runs in the browser rather than an app, which is the only way this one works.
"Big" and "large" both come up too, in both directions. Resize image big means shrinking a big scan or a modern phone photo down; it works the same as any other resize, with no megapixel ceiling to hit first since nothing uploads to a server. Resize image big size means the identical shrink, just phrased with an extra word. Resize image large is the plain-English version of the same request. Going the other way, to resize image big to small just means typing a smaller width or picking a lower percentage; nothing about the tool changes.
To resize a jpeg photo or resize jpg file, drop it in the same as any other format — nothing format-specific to configure. Prefer resize png image over jpg? Same box, same result, transparency kept intact.
Need to bulk resize photo files rather than just one? Drop several in and resize multiple images at once (or resize multiple image at once, singular) — each keeps its own width setting if you set them individually, or share one target size across the whole batch. Just resize online, no software, and if what you actually need is resize resolution image online rather than pixel dimensions, that's the same slider under a different name. Picture resize and online resize picture both name this same browser-only resizer: drop a file in, set a width or percentage, download. Resize image free online adds "free" but points at the identical tool. A plain file resize online skips "image" or "picture" altogether but still lands here. It handles resize images png, resize picture png, resize png pictures and resize webp exactly the same way it handles JPG.
Resize image pixels is the core control on this page: type a width or height in pixels and the other side follows automatically if proportions are locked. Resize image without losing quality is really about the direction: shrinking never loses quality beyond the pixels you remove, since fewer pixels compress and display cleanly either way. Resize image avif works the same as any other format here, output included.
Resize image dimensions means the width-and-height fields above — type either one and the other follows if the lock is on. Resize image dimensions online is that identical pair of fields, just described as a web tool. So does resize image dimensions in cm directly, though the cm figure has to convert to pixels first since screens don't work in physical units directly. Resize image dpi and resize image dpi pixels matter mainly for print: 300 DPI at a given physical size tells you the pixel dimensions to type in here. A resize image cm question and a resize image cm online search both need that same pixel conversion first, since the fields on this page take pixels, not centimetres.
Resize image download means the export button above — no installer, just the finished file. Resize image download free is that same button, with "free" spelled out for anyone checking. Is there a separate resize image download for Windows? No — the same browser page runs identically on Windows 11 or anywhere else, and the export button above is the whole download.
Resize images bulk and resize image bulk both mean the same thing: drop several files in and each gets its own pass. Resize image batch describes the identical workflow once more, just a different word for the same drop zone. Resize image by pixel and resize image by size are really the same two fields on this page — width or height in pixels. So is resize image by ratio itself, just approached as a percentage instead, and resize image by mb belongs on the compress page instead, since megabytes are a file-size question, not a dimension one.
Resize image but keep quality is the whole design goal: shrinking removes pixels honestly rather than blurring them, so the result looks sharp at its new size. Resize image bigger works the same fields in reverse, with the honest caveat from above: past the original size, stretching alone goes soft, and the upscaler is the tool for genuine enlargement.
Developers asking about resize image css usually want the width and height attributes or the object-fit property in their own stylesheet, not a pre-resized file — this page is still useful first, for shrinking the source image before it ever reaches that CSS. A resize image canvas or resize image canvas online question is really describing the mechanism honestly: the resizing happens on the HTML canvas built into your browser, the same technique the compress and crop pages use.
There's no resize image add white space option here, and no resize image expand either — this only scales the pixels that already exist, it doesn't pad a photo onto a bigger canvas; for that, an image editor with a canvas-size feature is the right tool. The same goes for resize image blur or resize image blur background specifically: this page never adds blur, it only changes pixel dimensions. Need to resize image crop instead — trim the frame rather than scale it? The crop tool is next door.
Word, Excel and PowerPoint can all resize a picture by dragging its corner handles, so a resize image excel question usually just means that built-in handle — fine for a quick shrink, though it doesn't re-encode the file the way this page does. Resize image com questions about where to find a plain, free resizer end here: this page, no install.
Resize image after upload works the same way regardless of where the photo came from — a camera roll, a download, a screenshot — since the step happens once the file is already on the page. Resize image aspect ratio online free is exactly what the locked-proportions toggle does by default, at no cost. Resize image and print pairs the pixel dimensions with the DPI table above, and resize image easy is really just: type a number, download.
Resize image enlarge runs into the same honest limit described above — genuine enlargement needs the upscaler, not a stretch. Resize image enlarger online free hits that identical ceiling too, free or not. Resize image enhance belongs there too, for the same reason. Resize image edit means typing precise numbers into the width and height fields rather than dragging a slider. Resize image exact pixels is the more literal way to describe that same typing-not-dragging approach.
For specific platforms, type the numbers straight in: resize image for youtube banner takes 2560 × 1440 pixels for the channel art, and resize image for instagram story takes 1080 × 1920, the size listed above under Sizes people actually get asked for. Resize image for facebook works identically, and resize image file size updates live as you type, so you can see the trade-off before you download.
You resize the image here by typing an exact width or a percentage and letting the proportions follow automatically along with it, with nothing ever uploaded to a server since the whole resize happens right inside your own browser's built-in canvas. You change size of an image by exact pixels or by percentage, whichever way you happen to think in, and the file downloads the moment you're genuinely happy with the preview shown above the button. You resize images free online here one at a time or as a whole batch of files at once, with each one keeping its own separate width setting or sharing one single target size across the whole set. You resize photo online free here regardless of the original source format, since JPG, PNG, WEBP and AVIF files all take that exact identical width-or-percentage step through this very same single tool. As a photo resizer free online tool it needs no account and no install of any kind whatsoever, just a file dropped straight into the page and a target width or percentage typed in directly.
This online image resizer free tool runs the whole resize entirely on the browser's own built-in canvas rather than a remote server somewhere else, which is also why nothing is ever actually uploaded anywhere at all. You reduce image size here specifically by pixel dimensions, which is a genuinely different job entirely from reducing file size in kilobytes — for that latter case, the separate compressor page is the right tool to reach for instead. As an image shrinker it removes real pixels honestly rather than simply blurring them together into mush, so a photo shrunk down to a smaller width still looks genuinely sharp at its new, smaller size. You shrink image files here down to an exact pixel width or a chosen percentage instead, with the height following along automatically too, as long as the proportions stay locked firmly in place. This image shrink step never adds any blur or padding of its own accord, it only ever removes pixels cleanly, so the result stays a faithful smaller copy of the original rather than a softened one.
Need the file itself smaller, not just the image — because it's actually a PDF? ScanReviver's compress PDF shows the size before and after at three strengths, and says so honestly if it's already tight instead of "compressing" it bigger.
Making a photo smaller is nearly lossless if you do it once, in one step, at high quality — which is what this tool does. Quality gets lost when you shrink, save, shrink again, or when you enlarge a photo beyond its real detail.
That is compressing rather than resizing. Use the compress page, give it your KB target, and it finds the settings for you.
Yes, by default. Type a width and the height follows. Untick "keep the proportions" if you deliberately want to stretch it.
Not in one step. Set the exact width and height here first, then take that result to the compress page and dial in the KB target — that two-step order is what a passport, visa or form upload with both a pixel and a file-size limit needs.
You can set a larger width here, but browser scaling only stretches the pixels you already have. To genuinely add detail, use the AI upscaler, which rebuilds it.
No. The resizing happens in your browser with the canvas API, so the file never leaves your device.
Anything your browser can display: JPG, PNG, WEBP, GIF and BMP. HEIC from an iPhone usually needs saving as JPG first, because most browsers cannot decode it.
Upload the photo, type the width or height you need (the other side follows automatically), and download — that's the whole process, no software to install.
Type 1080 in the width field for a feed post, or set 1080 × 1920 for a Story. Proportions stay locked so the photo won't stretch — it all runs in your browser, nothing uploaded. Search resize image for Instagram and this is that tool: type 1080 for a feed post, or 1080 × 1920 for a Story. Resize an image for Instagram, with "an" added, points at the identical page.
Drop your JPG into PicReviver's resizer, set a width or pick a percentage, and download. The file is never uploaded since everything runs in your browser.
Yes. PicReviver's resizer runs entirely in your browser — no software to install, no account, no upload needed.
Yes — this picture resizer has no account wall, no watermark, and gives you the real full-size file to download, not a locked preview.
Yes — resize image without quality loss is what happens when you shrink in one step, at high quality, which is what this tool does. Quality only suffers if you shrink, save, then shrink again, or if you try to enlarge past the real detail — for that, use the AI upscaler instead.
Resize image for printing by matching pixels to the print size at 300 DPI: about 1200 × 1800 px for a 10 × 15 cm print, scaling up from there. How to resize an image to print starts with the target size in centimetres or inches, then multiplies by 300 DPI to get the pixel count for the width field above. The shop-printing case is slightly different — how to resize an image for printing at a professional lab uses the same 300 DPI math, but check their upload page first, since some labs want a DPI tag embedded in the file, which this tool doesn't add.
No — resize image for instagram without cropping is exactly what happens by default: only pixel dimensions change, nothing gets cut off. If the ratio doesn't match what you need, use crop first, then resize.
Resize image to 20kb is a compress job, not resize — see the compress page for that. Ai resize image isn't a thing here either; it's plain browser-native scaling. For AI-rebuilt detail when enlarging, that's the upscaler.
Resize image to facebook cover size by typing 851 in the width field here — a Facebook cover photo displays at 851 × 315 px on desktop. Untick "keep the proportions" if your original isn't already close to that ratio.
Yes — type a width (or pick a percentage) and press resize; that's change image pixel size online free in full. If you need a KB number instead of pixels, that's the compress page.
Not in one step — resize image pixel and kb both really means two passes: set the pixel dimensions here first, then hit your KB target on the compress page. Doing it in that order gives a cleaner result.
