WebM to FLAC: extract audio
Pull the soundtrack out of a WebM video and save it as FLAC. Your video stays on your device: nothing is uploaded.
How to convert WebM to FLAC
- Add your WebM files. Drop one or more .webm files on the box above, or tap it to pick them from your device.
- Let it convert. The first video you convert loads the converter once (about 31 MB, then cached). After that it runs on your device; a progress bar shows how far along it is.
- Download the FLAC. Press Download next to each file. Nothing was sent to a server, so close the tab and it's gone.
What is a WebM file?
WebM is an open video format made for the web, usually VP8 or VP9 video with Vorbis or Opus sound. Screen recorders and browsers often save WebM.
What is FLAC?
FLAC is lossless compressed audio: the same sound as a CD or studio master at roughly half the size of WAV.
Why convert WebM to FLAC?
WebM is great for web pages and open-source players, but iPhones, many editors, WhatsApp and some social networks don't accept WebM. FLAC is the better choice for hi-fi music libraries and archiving; keep in mind files are large and many phones, cars and apps don't play FLAC.
Will I lose quality?
No. FLAC is lossless, so every pixel that WebM gave us is kept exactly.
Private by design
Most online converters upload your file to their servers. This one doesn't: the converter itself is loaded into your browser and works offline from there, so your videos never leave your phone or computer.
Questions
Is this WebM to FLAC converter free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
Are my WebM files uploaded?
No. The conversion happens inside your browser on your own device. Nothing is sent to us or anyone else.
Can I convert WebM to FLAC on iPhone or Android?
Yes, in a modern browser. Phones are slower than computers for video, and very long videos can run out of memory on older phones.
Can I convert several files at once?
Yes. Drop as many as you like; they are converted one after another and each gets its own download button.
Is there a file size limit?
No fixed limit, but your browser has to hold the whole file in memory, so files over about 2 GB may fail.
