Can I edit only selected frame durations?

Yes. Select any group of frames and apply one duration to that selection, or use Apply to All when the complete animation needs uniform timing.

Do crop, resize, rotation and effects apply to one frame?

No. Those visual operations apply consistently across the GIF so every exported frame keeps the same canvas geometry and treatment.

What do the optimization options change?

Balanced and Maximum cap the available palette more aggressively than None. Remove Duplicate Frames can also merge consecutive identical frames while preserving their combined duration.

Can the editor restore the original after several changes?

Undo and Redo cover committed edits during the session. New GIF clears the current document so another file can be opened.

Frequently asked questions

About GIF Editor

GIF Editor exposes the structure hidden inside an animated GIF. Frames can be selected, reordered, trimmed or removed, and their delays can be corrected individually—useful for cutting an awkward pause or emphasizing one step in a short demonstration.

Whole-animation transformations keep every frame aligned while resizing, cropping, rotating or applying visual effects. Export controls balance palette richness against file size and can consolidate consecutive duplicate frames without shortening their intended display time. Decoding, preview and re-encoding remain local to the browser.
