Frequently Asked Questions
How do I convert audio files online?
Pick the converter you need (for example MP3 to WAV), drop in your audio file, and download the result. Conversion runs on our server inside a locked-down, network-isolated sandbox and finishes in seconds - there is nothing to install.
Is my audio kept private?
Yes. Every conversion runs ffmpeg inside a hardened bubblewrap sandbox with no network access at all, so your audio can never leave the server. Files are processed in memory, all tags and metadata are stripped, and everything is deleted the instant your download is ready.
Which audio formats are supported?
We support the most common formats - MP3, WAV, FLAC, AAC, M4A, OGG and WMA - in the most-requested directions. Lossless options (WAV, FLAC) are great for editing and archiving; compressed options (MP3, AAC, OGG) keep files small.
Will converting between formats reduce quality?
Converting to a lossless format (WAV/FLAC) preserves exactly what is in the source. Converting to a compressed format (MP3/AAC/OGG) re-encodes at a high-quality setting that is virtually indistinguishable for normal listening. For the best results, start from the highest-quality source you have.
Is there a file size limit?
You can convert audio files up to 250 MB - plenty for long recordings, full albums and podcasts. Everything is processed privately in memory and deleted the moment your download is ready.
