GIF Fade In & Out

Blend the existing GIF frames with a solid background at the beginning and end. This is a color fade, not a partial-transparency effect: transparent areas are flattened against your chosen color.

Choosing your settings

Set either duration to zero to disable that end. Their sum must not exceed the GIF duration. Existing frames supply the fade steps; sparse animations may look abrupt. First and last enabled endpoints reach the background color.

If the result needs another pass

Try a longer animation with more frames for a smoother effect. No extra frames are invented, and GIF palette quantization can cause banding. Choose a background that matches where the GIF will appear.

GIF timing note: missing, 0 ms and 10 ms frame delays are read as 100 ms. Other supported delays are retained unless the task changes timing or the frame sequence. Re-encoded animation may therefore differ from a viewer that handles unusually short delays differently.

Good to know

Is the output transparent?

No. The color fade produces an opaque GIF. Existing transparent pixels are filled with the selected background color.

Will this make the GIF longer?

No. It changes pixels in existing frames while keeping normalized frame delays and the source loop setting.
