Is my video uploaded to a server?

No. The entire conversion happens inside your browser using the HTML5 File API, Canvas, and gif.js. Your video file never leaves your device and no data is sent to any server.

What video formats are supported?

Any format your browser can play natively: MP4 (H.264), WebM (VP8/VP9), MOV, and OGG. AVI and MKV are supported in browsers that have the right codec installed, but MP4 and WebM have the widest support.

Why is the GIF file so large?

GIF is an older format with a 256-color palette per frame and no inter-frame compression, so it is inherently much larger than modern video codecs. Reducing the output width, lowering the FPS, or shortening the clip duration are the most effective ways to reduce GIF file size.

Why does conversion take a while?

gif.js encodes every frame individually in a Web Worker on your CPU. Higher FPS, wider output, or longer clips mean more frames to encode. A 3-second clip at 10 FPS and 320 px width typically encodes in a few seconds; a 10-second clip at 15 FPS and 640 px width may take 30+ seconds.

What is the recommended clip length?

Keep clips under 10 seconds. Longer clips produce very large GIF files and take significantly longer to encode. For longer content consider multiple shorter GIFs or use a video format like WebM or MP4 instead.

Can I loop only part of the video?

Yes. Use the Start Time and End Time fields to trim the section you want to convert. Only frames within that range are sampled.

Summary

Video To GIF Converter lets you turn any short video clip — MP4, WebM, MOV, or AVI — into an animated GIF file entirely inside your browser. You control the frame rate, output width, and the start/end time of the clip. Frames are sampled from the video using HTML5 Canvas and encoded into a GIF with gif.js. No file is ever uploaded to a server; all processing happens locally on your device.

How it works

Select a video file from your device (MP4, WebM, MOV, AVI, or similar).
Preview the video and optionally set a start time and end time to limit the clip length.
Choose the output frame rate (FPS) and resize width to control GIF size.
Click "Convert to GIF" — the browser samples frames from the video using Canvas.
gif.js encodes all sampled frames into a single animated GIF file in the browser.
Once encoding is complete, preview the GIF and download it with one click.

Use cases

Create a GIF from a short screen recording to share in documentation or chat.
Extract a looping reaction clip from a video for social media.
Turn a product demo video into an embeddable GIF for a landing page.
Convert a WebM or MP4 clip captured in the browser to a shareable GIF.
Make a GIF from a funny video moment without installing any software.
