What is WebM?
WebM is an open, royalty-free format designed for the web. It streams efficiently in browsers but is less common as a download.
What is FLAC?
FLAC compresses audio losslessly, cutting file size by roughly half while keeping every detail of the original. It is the usual choice for archiving music.
Questions
Is the WebM to FLAC converter free?
Yes, it is free with no sign-up and no watermark. There is no cap on how many files you can convert, and nothing to install.
Do my files get uploaded to a server?
No. The conversion runs entirely in your browser using code that loads onto your device, so the file is read, converted, and downloaded locally. It never reaches us or anyone else.
Will converting improve the quality?
No. FLAC is lossless, but it can only preserve what is already in the WebM; it cannot restore detail that lossy compression has already discarded. The file may also be larger.
