Drop in any video file. One file at a time keeps the output predictable, and the convert button stays disabled until a file is in place.
The result comes back as a watermarked video. Then choose your logo image below.
Most online converters work the same way: you upload a file, it lands on somebody's server, gets written to a temporary folder, and is deleted afterwards. That is fine right up until the day you are converting an unreleased product mockup, a signed contract, or a client's bank statement — because all you get is a promise, not a fact.
This converter never sends your file anywhere. The work happens with JavaScript inside the page you are already looking at, so the bytes never leave your device. That is why there is no upload bar, no "file too large" ceiling, and nothing left behind on a server to delete.
There is no account to create and no watermark to remove. It also keeps working offline once loaded, which matters on a train or a patchy office Wi-Fi. If you are converting the same kind of file constantly, an automated pipeline is the better route — that is what our software solutions are for.
The clip is re-encoded end to end. A JPG logo appears as a solid block — use a transparent PNG.
Keep the original file until you have checked the output. If the result is not what you expected, try one of the related tools below rather than converting the same file repeatedly.
These tools cover one-off jobs. If you need a converter built into your app, a pipeline that handles thousands of files, or a team set up with the right tooling, that is a build job — and we do those.
