Free video and audio tools that never upload your files

Video files are large and often personal: a family clip, a recorded meeting, a lecture, a voice note from your phone. Many online converters ask you to upload the whole file to their server before you get anything back. The tool on this page works differently. The conversion code runs inside your browser, so the file never leaves your phone or computer.

Today there is one tool here, the Video to MP3 converter. It takes a video or audio file you already have and saves its sound as an MP3 or an uncompressed WAV. You can choose the MP3 bitrate, switch to mono, trim the start and end, and convert several files in one go with a single ZIP download. Common formats such as MP4, MOV, M4A and WAV open in every browser, and a few more depend on the browser you use. More tools may be added over time.

It is also worth knowing what it does not do. It works only with files on your device, so it cannot download audio from YouTube, TikTok or other links, and protected files such as purchased movies will not open. It produces audio only, not video. It is free, has no daily limit, adds no watermark and needs no account.
