How to resize images online

  1. Add your images

    Drop JPEG, PNG, or WebP files onto the tool, click to browse, or paste from your clipboard. You can queue a whole batch at once.

  2. Choose how to size them

    Scale by percent, cap the longest edge, fit each image inside a width and height box, or set exact pixels. Presets and a don’t-enlarge guard cover common cases.

  3. Check each result

    Every image re-renders as you refine. Each row shows the original and new dimensions and the resulting file size, with aspect ratio locked so nothing stretches.

  4. Download

    Save any image on its own, or grab the whole batch as a single ZIP. Resized files keep their original format.

Why use this tool

Batch resizing with ZIP download

Queue any number of images, apply one sizing rule to all of them, and download the results individually or as a single ZIP archive.

Four ways to size

Scale by percent, cap the longest edge, fit inside a maximum width and height, or set exact pixel dimensions. Portrait and landscape are handled correctly.

Presets for avatars, social, and thumbnails

One tap jumps to common targets: a 512 pixel avatar, a 1080 pixel social square, or a 1280 by 720 thumbnail box.

Aspect lock and a no-enlarge guard

Width and height stay proportional unless you unlock them, and the guard stops small images from being blown up past their original size.

Keeps the original format

JPEG stays JPEG, PNG stays PNG, WebP stays WebP, each saved with a -resized suffix so the originals are left untouched.

Local and free

Resizing runs on your device with no upload, no signup, and no watermark stamped on the output.

About this tool

This resizer changes the pixel dimensions of a whole batch of JPEG, PNG, and WebP images at once. Drop in as many files as you like and pick one sizing rule for all of them: scale everything to a percentage of its original size, cap the longest edge at a fixed number of pixels, fit each picture inside a maximum width and height, or set an exact width and height. Portrait and landscape images are measured correctly in every mode, so a mixed folder comes out consistent.

Aspect ratio stays locked by default, so nothing is stretched unless you turn the lock off to force exact dimensions. A don’t-enlarge guard keeps small images from being scaled up past their original size, and one-tap presets jump to common targets like a 512 pixel avatar, a 1080 pixel social square, or a 1280 by 720 thumbnail. Each row shows the original and new dimensions and the resulting file size as you refine, and every image keeps its original format. Both sides are capped at 8192 pixels, the ceiling browsers place on a canvas.

Every image is processed on your device and nothing is uploaded, so private photos and screenshots never leave the browser. Resizing changes dimensions rather than compression, so when you want a lighter file at the same size, reach for the image compressor. To change an image’s shape instead of its scale, start with the image cropper, and to work out matching dimensions for a target ratio, use the aspect ratio calculator.

Frequently asked questions

How do I resize multiple images at once?
Drop or paste several images, pick a sizing mode, and the whole batch is resized live. Save each one on its own or download everything as a single ZIP.
Will resizing reduce the quality?
Making an image smaller keeps it crisp. Enlarging past its original size cannot add detail that was not there, so it looks softer; the don’t-enlarge guard prevents that by default.
What is the difference between fit-in-box and exact size?
Fit-in-box scales each image to sit inside a width and height without distorting it. Exact size sets literal dimensions, which can stretch an image if you unlock the aspect ratio.
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser. Your images never leave your device and are never sent to a server.
What formats are supported?
JPEG, PNG, and WebP. Each resized image keeps the same format as the one you dropped in.
