Browser video editor

Online Video Editor that keeps your files private

No uploadNo signupMulti-trackFrame-accurate

This is a video editor that runs entirely inside your browser tab. When you drop a file onto the page, the bytes stay on your device. There is no upload step, no cloud rendering queue, and no account to create. The timeline, the preview, and the final export all run against WebCodecs and a build of FFmpeg compiled to WebAssembly, so the codebase behind the editor is the same one that powers professional post-production pipelines, just running locally.

Why browser-local editing

The project picker below lists anything you have already started, stored in your browser as IndexedDB. Clicking New Project spins up a fresh timeline ready for media, transforms, text tracks, and a multi-take source monitor. Projects are scoped to your browser profile, so switching laptops means starting over, but it also means nothing about your work is replicable from outside your machine.

Why build this way when the big incumbents upload everything. A few reasons. Privacy-sensitive footage (unreleased product demos, patient recordings, internal training, investigation clips) should not be sitting on a third-party server. Creators who picked CapCut for its price tend to re-evaluate every time its Pro plan doubles. And an editor that runs in any browser has no app-store dependency, which removes a category of platform-risk that mobile-first tools carry. Running in the browser, with no upload, is a small choice that sidesteps each of those separate concerns at once.

What this editor does

Multi-track timeline

Video and audio tracks stack independently. Drop B-roll onto a second track, cross-fade audio, and trim individual clips without touching the rest of the timeline.

Frame-accurate seek

WebCodecs decodes individual frames on demand. Scrubbing is precise, not approximate, so edit-in and edit-out points land where you set them.

Source monitor

Review raw footage before placing it on the timeline. Mark in and out points, then drop only the selected range into the edit.

Transforms and text

Per-clip scale, position, and rotation. Text overlays with keyframable position and opacity so titles and lower-thirds animate in and out.

Runs in your browser

Chrome, Edge, Firefox, Safari. No installer, no admin rights, no IT ticket. The page itself is the application.

Export to MP4

Final output is H.264 video and AAC audio in an MP4 container, the combination every social platform transcodes cleanly.

How to Edit a Video in Your Browser

1 Open the editor

Click New Project. The page initialises a fresh timeline inside your browser tab.

2 Drop in your footage

Drag a video file onto the source bin. The file is read locally; nothing is uploaded.

3 Edit the timeline

Cut clips, arrange tracks, add transforms and text. Scrub with frame-accurate seek to find the right frames.

4 Export to MP4

Click Export. The final render runs in a Worker using FFmpeg WASM and saves an MP4 to your device.

Frequently asked questions

Is this video editor free?

Yes, fully free. No trial, no credit card, no watermark on exports. Future features for regulated industries may sit behind a paid tier, but the core editing flow described on this page stays free.

Do my videos get uploaded anywhere?

No. Files open locally through the browser file picker, move into a Worker for processing, and the final export is written back to your device. Open the browser DevTools Network tab during an export if you want to verify that no upload request is made.

Do I need an account?

No account, no email, no signup. The page loads and the editor is ready. Projects persist in your browser via IndexedDB, so returning to the page on the same device and browser profile shows what you left off on.

What video formats work?

MP4, MOV, MKV, WebM, AVI, and most other containers that FFmpeg recognises. Output is always MP4 with H.264 video and AAC audio, which plays on every modern device and uploads cleanly to every social platform.

Does this work offline?

The page needs an internet connection on first load to pull down the application code and the FFmpeg WASM binary. After that, the tab keeps working if your connection drops, because no part of the editing flow makes a network request.

Is there a file size limit?

No arbitrary cap, but the practical limit is your device RAM. Chrome and Edge can usually handle clips up to about two hours at 1080p on a modern laptop. Compress or trim beforehand if you hit a memory ceiling.

How does this compare to CapCut?

CapCut has more AI effects and a broader template library. VidStudio runs in the browser without uploading your footage, has no account requirement, has no app-store dependency, and does not grant any rights over your content. Pick based on whether AI features or content ownership matters more for the specific edit.

Your video never leaves your device

All processing happens locally in your browser, and your files never leave your device. The editor reads your video file through a standard browser file input, holds the bytes in memory, processes them in a Web Worker against WebCodecs and FFmpeg WASM, and writes the final MP4 back to your disk. No upload, no cloud rendering, no external copy.

You can verify this yourself. Open DevTools, switch to the Network panel, filter to XHR and fetch requests, drop a file in and hit Export. You will see the initial page load and the one-time pull of the FFmpeg WASM binary. You will not see your video going anywhere. The same check works against any editor that claims to be browser-local.
