Cut, rearrange, and merge video clips without uploading a single frame.

Most video editing tasks don't need a full desktop application. Trimming a clip, removing a shaky intro, or rearranging two scenes are quick jobs — but traditional editors require installation, account sign-up, and sometimes hefty subscription fees. Online services that do offer this work often upload your file to a remote server, raising obvious privacy concerns for footage that might include people, locations, or sensitive content.

Handytool's video editor solves both problems. It runs directly in your browser using FFmpeg compiled to WebAssembly, which means the full power of FFmpeg is available entirely offline — no server ever sees your file. Editing is frame-precise: scrub to any frame, make a cut, delete what you don't need, and reorder the remaining clips. The output is stitched back together using stream-copy mode, so there's no quality loss and no waiting for a slow re-encode.

Privacy is the core design principle here. Every cut, deletion, and reorder operation runs inside your browser tab using FFmpeg WebAssembly. No file is sent over the network, no account is required, and nothing is logged. You can disconnect from the internet entirely and the tool still works.

This matters for footage that includes family members, clients, medical procedures, or any other content you'd rather not hand to a third-party cloud service. With Handytool, the only copy of your video is the one on your hard drive.
