Why is my GIF bigger than the original MP4?

GIF has no efficient motion compression the way H.264 does — every frame is stored close to independently with only a 256-color palette. A short, high-motion clip can produce a GIF several times the source's size. Trimming the clip shorter is the most effective fix.

Can I convert a long MP4 to GIF?

Technically yes, but the result will likely be huge and slow to load. GIFs work best for a few seconds up to around 15. Use Trim Video first to cut down to just the moment you want animated.

Why is the frame rate fixed at 10fps?

10fps is the practical sweet spot for GIFs — smooth enough for reaction clips and UI demos while keeping file size manageable. Sampling at a source's native 30 or 60fps would roughly triple output size for little perceptible gain.

Will the GIF have sound?

No — GIF has no audio channel at all, a structural limitation of the format itself. If you need the audio, use MP4 to MP3 to extract it separately.

Does the GIF loop forever?

Yes, by default (-loop 0) — standard for GIFs used as reactions, UI demos, or embeds.

Is there a daily limit on conversions?

No artificial cap beyond your account plan's file-size limit — convert as many clips as you need.

What is MP4 to GIF?

MP4 to GIF turns an MP4 clip into a looping, silent, universally-viewable animated GIF — the format that auto-plays in any browser, chat app, or forum post without needing a video player. This isn't a container swap: FFmpeg decodes your MP4 frame by frame, samples it down to 10 frames per second, scales the picture to 480 pixels wide using Lanczos resampling for sharp edges, and re-encodes the sequence as a single looping GIF.

GIF has real limitations compared to a video codec — only 256 colors per frame, no efficient motion compression, and every added second costs roughly the same amount of data rather than compressing better. That's why keeping the source clip short (a few seconds up to about 15) produces a far more usable result than trying to GIF-ify a long MP4 recording. If your clip needs trimming first, the Trim Video tool can cut it down before you convert.

The whole conversion runs inside your browser via FFmpeg compiled to WebAssembly, so a screen recording, a phone clip, or anything you'd rather not upload to a random GIF-maker site never leaves your device.

Need to go back the other way? GIF to MP4 converts a GIF into a proper video, and Trim Video can shorten a clip before converting it.

How It Works

FFmpeg decodes the MP4's video stream, applies a filter chain that samples frames down to 10 per second and scales to 480px wide with Lanczos resampling, then encodes the result as a GIF with an infinite loop flag (-loop 0). Because this is a full decode-and-re-encode rather than a stream copy, processing time scales with clip length and resolution.

How to Use

1
Upload your MP4 file
Drop an .mp4 clip onto the upload area — ideally under 15 seconds for the best result.
2
Trim first if needed
Use Trim Video beforehand if your source is longer than you want animated.
3
Click Convert to GIF
FFmpeg decodes, samples to 10fps, and scales to 480px wide with Lanczos resampling.
4
Preview and download
Check the animation plays smoothly, then save the finished GIF.
