What is a centisecond delay?

GIF frame delays are stored in hundredths of a second (centiseconds). A delay of 10 means 0.1 seconds per frame, giving 10 frames per second. A delay of 100 means 1 second per frame.

Does this tool reduce GIF file size?

Removing frames directly reduces file size because each frame stores compressed pixel data. Reducing delay does not change file size.

Is the output GIF lossless?

The export re-encodes the GIF using an 8-bit color palette (256 colors), which is the GIF standard. Some color fidelity may be reduced compared to the original if the source had a custom palette.

What is the maximum supported GIF size?

There is no hard limit, but GIFs larger than 20MB may be slow to decode depending on your device. Complex GIFs with many frames process in 3-10 seconds in most browsers.

Can I add new frames or change content?

This editor focuses on timing and frame removal. For adding new frames or changing pixel content, a full GIF creation tool like the Animated GIF Converter is recommended.
