Video Zoom
Zoom into a video in your browser — pick a zoom level and which part to keep, then download an MP4 at the same size. Nothing uploaded.

MP4, WebM, MOV…
Add a video to begin. The first run loads the engine (~25 MB) once.
How to use
- Drop a video in, or tap the box to choose one.
- Pick a zoom level (how much to magnify) and which part of the frame to zoom into.
- Press Zoom & download — the result keeps the original size and quality, just closer in.
FAQ
Is my video uploaded anywhere?
No. The zoom is done entirely in your browser with ffmpeg compiled to WebAssembly, so your video never leaves your device. The engine (about 25 MB) downloads once on first use, then is cached.
How does the zoom work?
It crops in to a smaller area of the frame (the part you choose) and scales that back up to the original size, so the subject looks larger — like a “punch-in” in video editing. Bigger zooms crop more, so very high zoom levels look softer.
Will the video get blurry?
Some softening is unavoidable because you are enlarging fewer pixels. We use a high-quality scaler to keep it as sharp as possible; smaller zoom levels (1.25×–2×) look best.
