One private converter for every format

Most online video converters work the same way: you upload your file to a server, wait in a queue, accept a cap on the free file size, and often end up with a watermark stamped across the result. VidShift does none of that. Every converter listed above runs entirely inside your browser using WebAssembly and WebCodecs, so your videos never leave your device. There is nothing to install, no account to create, and no limit on file size beyond your own device's memory.

Because the work happens on your machine, two things follow. First, it is genuinely private: a wedding video, a confidential recording or a personal clip is never transmitted anywhere. Second, there is no upload wait, so for many conversions the tool starts working the instant you drop the file in, rather than after a multi-gigabyte transfer.

Where the codecs allow it, such as MOV to MP4 or MKV to MP4, VidShift simply repackages the existing streams into the new container. This is a lossless remux that keeps the original quality bit for bit and usually finishes in seconds. When a true re-encode is unavoidable, like MP4 to WebM or turning a GIF into an MP4, it happens locally at the quality you choose, with a progress bar and time estimate so you always know where you stand.

This hub is where every format pair lives, and it is the first place new ones appear. If the conversion you need is not listed yet, the general-purpose video converter handles a wide range of inputs and outputs directly. Bookmark this page as your home for free, private, in-browser video conversion.
