Create GIFs from imagesNew
Turn PNG, JPEG or WebP images into an animated GIF โ set the order, delays and loop.
Learn how โNew ยท Desktop 0.4.0 & CLI 0.7.0: create GIFs from images ยท signed for macOS & Apple Silicon โ
Fix, edit and create GIFs โ without breaking optimized GIFs.
GIFmeta is a free, open-source desktop app, Rust CLI and library for animated GIFs: fix loops and timing, delete, insert, duplicate and re-order frames safely โ or turn a stack of images into a new GIF.

The problem
Most GIFs you find online are frame-optimized.
Each frame usually only stores the pixels that changed since the previous one โ that's what keeps files small. But it means you can't just remove a frame or tweak a delay in isolation: every frame after it gets drawn on top of the wrong picture, and the animation falls apart.
๐
Keyframe
A full image. All the pixels it needs are stored with it, so it can be edited safely on its own.
ฮ
Delta frame
Only the changed pixels are stored, drawn on top of the previous frame โ inheriting its timing and pixels. Edit carefully, or rebuild.
GIFmeta understands how frames depend on each other โ so your edits stay safe.
How it stays safe
Delete a frame? We rebuild what depended on it.
GIFmeta replays the original animation and the modified one side by side. For every frame that stays, it compares the canvas the frame would be drawn on: if it matches the original, the frame is copied as-is โ lossless. If it doesn't, because a frame it depended on was deleted, the frame is written as a full image of exactly how it looked before.
Usually only one or two frames need rebuilding. Rebuilt frames get an exact palette whenever possible; only frames with more than 256 colours are colour-reduced, with a warning.
- Lossless copy for frames that don't depend on the change
- Dependent frames rebuilt automatically as full images
- Total duration preserved โ the delay moves to the previous frame
- Tested: pixel-identical output on a 40-frame optimized GIF

Everything you need to fix โ or make โ a GIF.
Small, focused and built with Rust speed. The same safe engine powers the desktop app, the CLI and the library.
โ
Insert & duplicate framesNew
Add an image as a new frame anywhere, or copy a frame to hold it longer.
Learn how โ๐
Re-order & reverseNew
Drag frames into a new order or play a GIF backwards โ even in optimized GIFs.
Learn how โ๐๏ธ
Safe frame deletion
Delete frames without breaking the rest โ dependent frames are rebuilt, the delay moves to the previous frame.
Learn how โโฑ๏ธ
Frame timing
Set one delay for all frames or override specific frames. Delays are in centiseconds (1 = 10 ms).
Learn how โ๐
Loop control
Loop forever or play a fixed number of times. "Plays once" GIFs stay that way.
Learn how โ๐
Detect frame-optimized GIFs
See which frames are full images (๐ keyframes) and which are delta frames (ฮ).
Learn how โโจ
Pretty & raw view
Render any frame exactly as it plays โ disposal-aware โ or view just the raw pixels it stores.
๐
Inspect
Size, frame count, duration, palette, transparency and loop setting โ also as JSON for scripts.
๐จ
Unoptimize
Convert selected frames to full images, or unoptimize the whole GIF into flat full frames.
โก
One-pass rendering
Render or export all frames in a single fast pass โ 15โ56ร faster than frame by frame.
