What GIF Resizer does
Resize an animated GIF while preserving its frame sequence. The tool keeps the operation focused and creates a separate result so the original remains available for comparison.
GIF Resizer uses a bounded server request with explicit input, time, output, and rate limits.
How to use GIF Resizer
Keep the original while using GIF Resizer. Review the entered values or selected file, run the focused operation, and save only a result that passes your checks.
- Select a short representative video, animation, or capture source and confirm the displayed duration and dimensions.
- Choose the required timeline range, frame, layout, audio, or output settings for the destination.
- Create the result and watch the complete preview, including transitions and the first-to-last loop boundary when relevant.
- Test the downloaded file in the target browser, player, editor, or publishing service before deleting the source.
Where GIF Resizer fits
Use this media workflow to prepare a short clip, recording, or animation for a known player, platform, presentation, or editing step. Decide the required dimensions, duration, frame behavior, audio state, and output format before processing so every setting has a clear purpose.
What to check
Review the full animation rather than only its first frame. Confirm the crop or dimensions and watch for palette banding, missing frames, or altered timing.
Review the whole timeline for correct framing, orientation, timing, animation loops, audio sync, captions, and legible overlays. A short representative clip is useful when choosing compression settings.
Privacy and limitations
Recordings created with browser capture APIs remain local. FFmpeg conversions upload only the selected input file or files and use temporary workspaces with best-effort cleanup after the request.
Browser capture support and playable codecs vary by device. Re-encoding may change quality, exact frame timing, metadata, transparency, or file size, and long or high-resolution media can exceed the documented request or memory limits.
