How to convert MP4 to GIF
- 1
Drop your MP4 file into the converter above, or click to browse. Nothing is uploaded — the file stays on your device.
- 2
Adjust the settings (width, frame rate, and trim). Tip: GIFs grow fast — trim to under 10 seconds, keep width at 480px, and use 12 fps. That combination stays under most chat apps' upload limits.
- 3
Click “Convert to GIF”. The conversion runs locally in your browser — larger files take longer, and a progress bar keeps you posted.

Why convert MP4 to GIF?
Video files need a player; GIFs just play. That's why GIFs still rule chat apps, documentation, pull requests, and marketing emails — they autoplay silently, loop forever, and need zero user interaction. Converting MP4 to GIF makes any clip embeddable anywhere.
Quality matters here: this converter generates a custom color palette from your actual footage (the classic two-pass FFmpeg technique) instead of using a generic 256-color palette, which visibly reduces banding and dithering artifacts compared to naive converters.

About the formats
MP4 MPEG-4 Part 14
MP4 is the most widely supported video format in the world. Built on the H.264 codec with AAC audio, it plays on every phone, browser, TV, and editing app, and offers an excellent balance of quality and file size. When in doubt, MP4 is the safe choice for sharing video.
GIF Graphics Interchange Format
GIF is the internet's animation workhorse: it autoplays silently everywhere — chat apps, docs, README files, emails — with no video player needed. The trade-offs are a 256-color palette, no audio, and file sizes that grow quickly with resolution and frame rate.
Frequently asked questions
Why is my GIF bigger than the MP4 it came from?
GIF is a 30-year-old format that stores every frame as an indexed image, with none of the motion compression MP4 has — so a GIF can easily be 5–10× larger than the source video. Keep GIFs short, small, and low-fps; that's what the trim, width, and frame-rate settings are for.
What settings work best for Discord and Slack?
Trim to a few seconds, set width to 480px and frame rate to 12 fps. For Discord's 8 MB no-Nitro limit, roughly 5–8 seconds at those settings fits comfortably; for very long clips, consider linking the MP4 instead.
Is this MP4 to GIF converter really free?
Yes — completely free, with no watermarks, no sign-up, and no conversion limits. The tool is supported by ads on this page, so the converter itself never asks you for anything.
Are my files uploaded to a server?
No. This converter runs entirely in your browser using WebAssembly (a browser build of FFmpeg). Your MP4 file never leaves your device — nothing is uploaded, stored, or seen by us, which also makes it safe for private or confidential files.
Is there a file size limit?
There's no hard limit. Because conversion happens on your own device, the practical ceiling is your browser's memory — files up to a few hundred megabytes work well on most computers. Very large files may be slow or fail on low-memory devices.
Why does the first conversion take a moment to start?
The first time you convert, your browser downloads the conversion engine (about 31 MB) once. It's cached after that, so later conversions start instantly — and they keep working even offline.
