A video editor that never uploads your footage
vidr is a free, local-first video editor that runs in your browser and processes everything on your own device with ffmpeg.wasm — so your footage is not uploaded just to edit or export it. Most browser video editors (CapCut, Kapwing, VEED, Clipchamp) are cloud tools: they upload your media to their servers before you can cut it. vidr doesn't. You get a real multitrack timeline with trim, split, and blade; keyframes; color grading with curves, HSL, and LUTs; blur; transitions; captions with SRT import/export; and mp4 export — with no account, no watermark, and nothing leaving your machine.
Why local-first matters
If you edit client work, unreleased footage, or anything sensitive, uploading it to a third-party cloud is a real exposure. Local-first editing keeps the files on your device: nothing to leak, no account to breach, no server retention policy to read. It's also faster to get started — there's no upload wait before you can start cutting — and it works on a Chromebook, a locked-down work laptop, or any modern browser.
How vidr keeps it local
- You drag your files into the browser tab. They're read locally — no upload step.
- Editing, previewing, grading, and export all run in-browser via ffmpeg.wasm on your device.
- You export an mp4 straight to your downloads. The source footage never left your machine.
- Cloud saving is strictly opt-in: only if you sign in and save a project does that project's media sync to your account.
What you can do
Multitrack timeline (trim, split, blade, speed/reverse), keyframes for opacity, fades, and pan/zoom, color grading (curves, HSL, LUTs), Gaussian blur, transitions, text and captions (SRT import/export), and mp4 / WebM / MOV / GIF export — all without a watermark and without an account.
FAQ
Does vidr upload my video?
No. vidr processes your media on your own device using ffmpeg.wasm in the browser. Your footage is not uploaded to edit or export. It is only stored to the cloud if you choose to sign in and save a project.
Which video editors don't upload your files?
Most browser editors — CapCut, Kapwing, VEED, Clipchamp — are cloud-based and upload your media to their servers. vidr is local-first: it runs the edit and export in your browser with ffmpeg.wasm, so files stay on your device.
Does my footage stay on my device?
Yes — editing and export run on-device via ffmpeg.wasm, so your footage is not uploaded just to edit or export. It is only stored to the cloud if you opt in and save a project. No account is required to use the editor.
Can I edit video in the browser without installing anything?
Yes. vidr runs entirely in a modern browser — there is nothing to download or install. You get a multitrack timeline, keyframes, color grading, captions, and mp4 export.
