How do I stabilize a shaky video in my browser without uploading it?

Open AnyTool's Video Stabilizer, drop in a shaky clip, pick a strength preset (Light, Medium or Strong), and it smooths the motion with a self-hosted ffmpeg single-pass deshake filter — with an optional crop/zoom to hide the wobble borders and a light sharpen. To be honest, single-pass deshake helps moderate shake and works best on short clips; it is not full two-pass vid.stab. Everything runs in your browser — no upload, no CDN, no watermark.

  • Single-pass deshake with Light/Medium/Strong strength
  • Optional crop/zoom to hide wobble borders + light sharpen
  • Best for moderate shake on short clips (not full two-pass vid.stab)
  • Self-hosted ffmpeg engine — no CDN, no upload

What is

Video stabilization

Video stabilization reduces unwanted camera shake to make footage look steadier. A single-pass deshake filter estimates and compensates motion in one go (fast, good for moderate shake), often paired with a small crop/zoom to hide the edge wobble. It is lighter than full two-pass analysis (e.g. vid.stab). Client-side stabilization re-encodes the video in the browser, so the file is never uploaded.

Frequently Asked Questions

No — it is processed entirely in your browser with a self-hosted engine.

The clip never leaves your device and there is no signup or watermark (files up to 400 MB).

It uses a single-pass deshake filter that helps with moderate shake and works best on short clips.

Being honest: it is not full two-pass vid.stab, so very heavy shake on long clips may only be partly smoothed.

Stabilizing shifts each frame, which can expose wobbly edges — an optional crop/zoom hides them.

There is also a light sharpen to recover some detail after the crop and zoom.

Detailed Explanation

Methodology

How Video Stabilization Works

AnyTool stabilizes shaky video in the browser with a self-hosted ffmpeg engine (no CDN). It applies the built-in single-pass deshake filter, with rx/ry search ranges scaled by the chosen strength and edge=mirror to fill borders. Optionally it follows that with a crop/scale zoom to hide the wobble borders the shake correction leaves behind, plus an unsharp pass to recover a little detail. The result is re-encoded H.264 + AAC and read back as an MP4 blob. The stock wasm core has no libvidstab, so this is honestly single-pass (not the two-pass vidstab analysis some desktop tools use). Single-threaded is deliberate: the multi-threaded core needs SharedArrayBuffer + cross-origin isolation (COOP/COEP), which would block cross-origin ad iframes.

  • Runs client-side — the video is never uploaded
  • Self-hosted ffmpeg core — no CDN
  • Built-in deshake filter (rx/ry per strength, edge=mirror)
  • Optional zoom crop/scale to hide wobble borders + unsharp pass
  • Single-pass (stock core has no libvidstab two-pass)
  • H.264 + AAC re-encode; no backend, no watermark, files up to 400 MB
Privacy & Security

Privacy vs Upload-based Stabilizers

Most online stabilizers upload your video to a server and cap the free tier or add a watermark. AnyTool stabilizes locally with a bundled engine, so the video never leaves your browser, there is no watermark and no signup (files up to 400 MB), and it works offline after the first load.
