Resize, Crop & Rotate GIF

Resize, crop, rotate, flip or change the canvas and aspect ratio of GIF, APNG and WebP animations.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Resize, Crop & Rotate GIF works

Animations are decoded into full frames in your browser (GIF with gifuct-js, APNG with UPNG.js, WebP frames with the browser decoder), edited, then written back out. GIF is encoded with gifenc plus our own frame optimiser; WebP, MP4 and WebM go through ffmpeg.wasm. Resizing uses area averaging with premultiplied alpha, so edges stay clean.

Input: GIF, APNG, WEBP, AVIF. Output: GIF, APNG, WEBP, MP4, WEBM.

Tips

Most image tools accept many files at once.
WebP and AVIF give much smaller files than JPG at the same visual quality.
Set a default image quality in Settings. Tools that do not choose their own quality use it.
