1. Pick a source
Select an MP4, MOV, WebM, or another video file. FrameForge previews it using the browser's native video support before starting FFmpeg.
Private browser video converter
Convert MP4 to GIF, trim clips, and extract audio without uploading your video.
FrameForge runs FFmpeg in your browser with WebAssembly, so your footage stays on your device while you build GIFs, social clips, thumbnails, and lightweight exports.

Local-first by design
FrameForge does the heavy work in your browser. Your file is read locally, processed locally, and downloaded locally. The site does not need a server upload step for conversion.
- Useful for creator clips, product demos, memes, thumbnails, and quick audio pulls.
- Works best in modern Chromium, Firefox, and Safari browsers with enough device memory.
- Large videos can take time because your computer is doing the encoding.

2. Shape the clip
Set start time, end time, width, frame rate, and output type. The command preview updates so technical users can see what will run.
3. Export locally
When you convert, FFmpeg.wasm loads in the page and writes the new GIF, MP4, WebM, MP3, or PNG into browser memory for download.

Video to GIF FAQ
Is this MP4 to GIF converter private?
Yes. The conversion runs in your browser using WebAssembly. Your media file is not uploaded to FrameForge for processing.
Why does converting a long video take time?
Video encoding is CPU-heavy. Short clips with lower width and lower FPS export faster and usually make better GIFs.
Can I extract audio from a video?
Yes. Choose MP3 mode, pick the time range, and FrameForge will export the selected audio segment locally.
What is the best GIF setting for social posts?
A width between 480 and 720 pixels, 8 to 15 FPS, and a clip under 6 seconds usually gives a good balance of motion and file size.
