Make an animated GIF smaller for an upload limit
Set the maximum file size required by a form, email service or portal. The file is processed locally, and the result shows whether it fits the selected limit.
What makes the file smaller?
Animated GIF size depends on frame count, frame rate and dimensions. This tool exports a looping GIF at a lower frame rate and lets you reduce its width for a smaller result.
Why an exact size is not always possible
Already-compressed files contain little removable data. The tool keeps the best safe result and reports when the requested limit cannot be reached without removing content or causing unacceptable quality loss.
FAQ
Are my videos uploaded to this website?
No. Video and audio files are processed locally in your browser. The server receives no file.
Can this convert MP4 and WebM?
Yes. The browser ffmpeg engine can export MP4, MOV, WebM, MKV, MP3, AAC, WAV, FLAC, OGG, OPUS, GIF and animated WebP when the device has enough memory.
Why is video conversion slower than image compression?
Video encoding is CPU-heavy. Large files, 4K footage and mobile browsers may take longer.
