About GIF Maker

OptiPix GIF Maker is a complete in-browser GIF studio: create, edit, optimize, and convert animated GIFs without ever uploading a file. Drop multiple images and they become frames you can drag-to-reorder, retime per frame, add per-frame text, duplicate, and preview live. Drop a video file (MP4, WebM, MOV) and trim with timeline sliders, choose your frame rate and output width — frames are extracted in your browser using FFmpeg.wasm and re-encoded with the gifenc library. Drop an existing GIF and OptiPix decodes it into editable frames for re-mixing. Or record up to 30 seconds of your screen via getDisplayMedia for tutorial GIFs. Editing options include crop, resize, speed (0.25×–4×), reverse, boomerang, top/bottom meme text, per-frame text overlays, and 16/32/64/128/256-color palettes. The optimizer drops near-duplicate frames and re-quantizes the palette to shrink file size by up to 70%. Export as GIF, MP4 (H.264 via FFmpeg), animated WebP, or split into individual PNG frames as a ZIP. Because every step is local, your screen recordings, video clips, and personal moments never leave your device — ideal for private tutorial GIFs, bug-report captures, and anything else you'd rather not upload.

How It Works

Image frames are drawn to a Canvas and encoded with the gifenc library. Video uploads are decoded by FFmpeg.wasm to extract individual frames at the requested FPS, then quantized and packed into a GIF. Screen recording uses getDisplayMedia to capture frames and feeds them through the same encoder.
