Loop Forge
Free online video to GIF maker and trimmer. Drop a clip, trim it, export a clean WebM loop or 8-bit GIF.
Take any video file (mp4, webm, mov), pick the in and out points, optionally crop and scale, render a re-encoded WebM clip or an 8-bit GIF. Useful for game devs who need a polished loop for a store page, devlog post, social share, or showreel.
Recording a clip is easy. Trimming it cleanly, exporting at a sane size, and avoiding a cloud round-trip for a 10-second loop, that part takes longer than it should. Loop Forge collapses the whole flow into the browser.
- 01Drop a video file (mp4, webm, mov), or click to pick one.
- 02Trim. Drag the in and out sliders, or scrub the video and hit Set from playhead.
- 03Optional. Set crop by dragging a region on the video, choose scale (25 to 100%), choose speed (1x to 8x to skip frames).
- 04Pick a format. WebM is small and embeds anywhere. GIF travels everywhere but weighs more.
- 05Render. WebM finishes in roughly clip-length wall time. GIF takes longer because each frame is quantized.
- 06Download. Files save as <source>-loop.webm or .gif.
- WebM output is re-encoded with the browser's native MediaRecorder. Codec varies by browser (VP9 on Chromium, VP8 on Firefox). Render time is roughly equal to the clip length.
- GIF output runs frame by frame through an in-browser Wu quantizer (15 fps, 8-bit palette). GIF renders take longer than WebM and files are larger, so reach for it when you actually need a GIF.
- Nothing leaves your machine. No upload, no server, no account.
Is Loop Forge free, and does it add a watermark?
Yes, it's free. No account, no upload, no watermark on the output, ever.
How do I make a GIF from a video online without uploading?
Drop the video onto Loop Forge, trim, and click Render as GIF. The file is quantized to an 8-bit palette inside your browser and saved straight to your downloads. Nothing leaves the tab.
What video file types can I import?
mp4, webm, mov, m4v, and mkv. Output is WebM (VP9 on Chrome and Edge, VP8 on Firefox) or 8-bit GIF.
WebM or GIF — which export should I pick?
WebM if you control where it embeds (devlogs, store pages, Discord, most modern blogs). Smaller, sharper, supports alpha. GIF if it has to autoplay on any surface (older forums, email, social previews). Larger and lower fidelity but truly universal.
Can I crop and scale before exporting?
Yes. Drag a region on the preview to crop, set a scale from 25% to 100%, and optionally speed up by frame-skipping (1x to 8x).
How long can my source video be?
There's no hard cap. The practical limit is your browser's memory. A few minutes is comfortable on most machines.
Does it work on a phone?
Yes. Mobile Chrome and Safari can both render, though long renders may be slower than on a laptop.
Where does my video get uploaded?
Nowhere. The clip stays in your browser tab. There is no upload and no server processing.
