Resize a PNG, JPG, or WEBP to the exact pixel size you need — right in your browser, with no quality-killing upload to a third-party server.
Whether you're sizing a profile picture, shrinking a photo for faster page loads, or fitting an image into a fixed banner slot, the Image Resizer gives you precise pixel control in seconds. Enter a width, a height, or both — and keep the aspect ratio locked so your image never looks stretched or squashed.
Everything runs locally using high-quality Lanczos resampling, the same algorithm professional editors use for sharp downscaling. Your image is never stored, so it's perfectly safe for personal photos and client work alike.

- Private — images never leave your browser session unsaved
Frequently asked questions
Does resizing reduce image quality?
Downscaling with our Lanczos filter keeps edges crisp. Enlarging beyond the original size can soften detail, since there are no extra pixels to invent.
Will it keep my transparent background?
Yes. The output is always a PNG with full alpha transparency preserved.
Is there a file size or dimension limit?
Uploads up to 10 MB are supported, which covers virtually all web and social images.
