Resize Image
Resize images to exact pixel dimensions or a percentage — one image or a whole batch.
Processed entirely in your browser. Your image is never uploaded to a server.
- Set an exact pixel width and height, or scale by a percentage.
- Lock the aspect ratio — enter one dimension and the other is worked out for you.
- "Don't enlarge" refuses to upscale a smaller image, so it never comes out soft by accident.
- Convert the output format (JPG / PNG / WebP / AVIF) in the same step if you need to.
- Batch-resize with one set of settings and download everything as a ZIP. Runs on your device — nothing is uploaded.

Overview
Resize images to an exact width and height, or by a percentage. Keep the aspect ratio locked so nothing stretches, switch on a "don't enlarge" guard to avoid blurry upscaling, and optionally convert the output to JPG, PNG, WebP or AVIF. Works on one image or a whole batch, entirely in your browser. To crop to a shape or fit an exact platform size, use Crop Image or the Social Media Image Resizer.
How to use it

- 2Enter a width and/or height, or switch to Percentage and pick a scale. Choose an output format if you want to convert.
- 3Check the before/after estimate, click Resize, then download the image or the whole batch as a ZIP.
