Frequently asked questions
Is my FLAC file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open a FLAC file without installing software?
Drop the .flac file on this page. It opens straight away in the Audio Waveform & Spectrogram, on Windows, macOS, Linux, Android and iPhone alike.
What if my FLAC file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really a FLAC file, you'll see an error or can switch to the hex view to look at the raw bytes.
Can I convert FLAC to another format?
Yes. The free file converter turns FLAC files into other formats in your browser as well, without uploading them.
