Frequently asked questions
Is Vidverter really free?
Yes. Convert, compress and trim up to 3 files at a time, up to 250 MB each, without sign-up or watermarks. Pro is for heavy users: unlimited batches, files up to 2 GB and ZIP downloads.
Are my files uploaded to a server?
No. Vidverter runs entirely in your browser and uses your device's own video encoders. Files never leave your computer or phone, so it is safe for private recordings, and there is no upload or download wait.
Which formats are supported?
Video: MP4, MOV (including iPhone HEVC), WebM and MKV. Audio: MP3, WAV, M4A/AAC, OGG and FLAC. You can save as MP4, WebM, MOV, MP3, WAV or M4A.
Why is it so fast?
Vidverter uses the video encoders built into your browser and graphics chip (WebCodecs), and skips uploading and downloading entirely. When only the container changes, the video is copied without re-encoding.
