GIF Resizer — Frequently Asked Questions
Is my GIF uploaded anywhere?
No. The GIF is decoded frame by frame in your browser and re-encoded on your device with a small open-source encoder. Nothing leaves your computer.
Does making a GIF smaller reduce the file size?
Yes, roughly in proportion to the pixel count — half the width and height is about a quarter of the bytes. Enlarging does not add detail and makes files bigger.
Does it keep the original frame timing?
Yes. Each frame's own delay is preserved, so GIFs with mixed timing (a long pause on the last frame, for example) play exactly as before.
Will the quality change?
Frames are re-quantised to a 256-colour palette built from the GIF itself, so the result is visually identical for almost all GIFs. Photographic GIFs with thousands of subtle shades may show slight banding; no dithering is applied to keep files small.
Will transparent GIFs stay transparent?
Yes. Transparent areas are kept as transparency in the output; edges are hard (GIF has no soft alpha).
