MP4 (MPEG-4 Part 14) and GIF (Graphics Interchange Format) are built for different jobs. MP4 is typically used for sharing, social media, streaming, while GIF is best for short loops, memes, reactions. Converting lets you open, share or upload your files wherever GIF is expected.

Frequently asked questions
How do I convert MP4 to GIF?
Add your MP4 files above, make sure GIF is selected and press Convert. The GIF files are ready to download a few seconds later — no installation or account required.
Why does the first conversion take a little longer?
The video engine (FFmpeg compiled to WebAssembly, about 30 MB) is downloaded once and then cached by your browser. After that, conversions start immediately — even offline.
Is there a file size limit?
There is no artificial limit. Because the conversion runs in your browser, the practical limit is your device memory — files up to around 1–2 GB work on most computers. Long videos take longer on phones.
Are my MP4 files uploaded to a server?
No. ConvertMathly converts files entirely inside your web browser using JavaScript and WebAssembly. Your files never leave your computer or phone, which makes it safe for private photos and documents.
Can I convert multiple MP4 files at once?
Yes — add as many files as you like. They are converted one after another and you can download everything in a single ZIP.
