Keep a baseline before changing anything
Save the original animation and note its file size, pixel dimensions, and purpose. Is the receiving service rejecting it, or is it simply slow to load? Find the destination’s actual requirement rather than choosing an arbitrary target.
Choose Resize an existing GIF in the browser tool, then import the original. Large source GIFs are rejected to protect browser memory. Alternatively, build a new animation from your original photos or a selected video interval.
Reduce the visual workload
For an image sequence, each retained frame should add meaning. Repeating a static screen may be replaced by a longer hold where the editor supports timing, while an important transition should remain understandable.
- For photo sequences, remove unnecessary introduction and ending pictures. For video, shorten the selected interval.
- For an existing GIF, compare keeping every frame with every second, third, or fourth frame. The tool combines skipped-frame delays to preserve duration; check whether the motion still reads clearly.
- Reduce the output dimensions and check text or facial detail at normal viewing size.
- Generate the GIF again and compare the reported bytes with the baseline. Keep the smaller acceptable result, not merely the latest export.
Choose a different delivery format when needed
A GIF has a restricted palette, so a busy photographic animation may show color changes even after careful sizing. If the destination accepts video and the source is already a video, consider sharing the video instead of forcing everything into a GIF.
No fixed percentage saving follows from these steps. Two sequences with the same dimensions can encode very differently. When testing a size limit, use the downloaded file’s actual size and confirm the receiving service accepts that exact file.
