Discord, TikTok & Widescreen Presets

Snap your crop area to 1:1 Square for Discord/Slack emojis and avatars, 9:16 Vertical for TikTok/Reels, 16:9 Widescreen, or 4:3 in one click.

Crop GIF, MP4, WebP, APNG & AVIF

Crop MP4, WebM, and MOV videos alongside animated GIF, WebP, APNG, AVIF, and static PNG/JPG images without breaking frame timing or alpha transparency.

Crop GIF & Crop Video Online (Free, No Uploads)

Whether you recorded your full desktop screen, want to zoom in on a reaction, or need to trim black bars off a video, our online GIF cropper and video cropper makes it effortless. Unlike basic image editors that flatten animations into a static frame, AnimTool crops every frame of your GIF, MP4, WebM, WebP, APNG, or AVIF in sync while preserving original frame delays and loop settings.

Working with transparent stickers or sprite animations? Check Autocrop transparent borders to automatically trim empty see-through margins around your GIF or APNG so your sticker fills the canvas cleanly.
