Audio Converter
Convert audio to MP3, WAV, AAC, FLAC, OGG or OPUS, or take the soundtrack from a video.
The audio converter turns MP3, WAV, M4A, AAC, FLAC, OGG, OPUS, WMA and AIFF files into MP3, WAV, AAC, FLAC, OGG or OPUS, and takes the soundtrack out of videos too. MP3 is picked for you, since practically everything plays it.
Almost any file
Images, vector art, video, audio, documents, spreadsheets, slides, ebooks and archives: more than 400 conversions. Before anything runs, Filebender says what a conversion will lose and estimates the size of video, audio and many pictures; other files show their size once converted. It compresses PDFs, pictures and videos to the size you choose.
No ads, no watermarks
With a free account: 20 files a day, 2 of them videos, each up to 500 MB. No plan has ads, and nothing is stamped on your files. A pass is one payment that never renews, and one you haven't used can be refunded in full.
Private by default
Files are deleted an hour after converting, or at once when you ask, and photo location is removed unless you choose to keep it. Photos converted to JPG, PNG or WebP are done on your device when your browser can, so they never leave it. They still need your account and count towards your plan.
How to use the Audio Converter
- Create a free account with Google or your email address, or sign in.
- Choose your files: drop them on the box, pick them from your computer, open them from Google Drive, or paste a link.
- Pick the format each file should become. The gear button has size, quality and other settings.
- Press “Convert”, then download each file, or all of them in one ZIP.
Lossless and lossy
WAV and FLAC keep every detail of the sound: WAV uncompressed and large, FLAC packed to roughly half that with nothing lost. MP3, AAC, OGG and OPUS leave out what's hard to hear, to make much smaller files. Converting a lossy file to a lossless format can't bring detail back; it only makes the file bigger.
Bitrate
Lossy formats are saved at the audio bitrate you choose in the settings, from 64 to 320 kbps, 128 kbps unless you change it. That suits speech and casual listening; 192 to 320 kbps suits music you care about. OPUS sounds good at lower bitrates than MP3, which makes it a fit for voice recordings. WAV comes out as 16-bit, like a CD.
Tags and cover art
Details such as the title, artist and album are removed by default, as a photo's details are. Tick “Keep photo details” in the settings to keep them. Cover art isn't carried into the new file.
Audio is converted on Filebender's servers and deleted an hour after converting.

Questions
Can I get an M4A out?
Not as M4A: choose AAC, the same kind of sound in a plain .aac file that most players open. When the original is already AAC and you don't trim it or set a size, the sound is copied across as it is, with no loss.
Does converting audio count as a video?
No. Audio conversions are ordinary files, even when the sound comes from a video. With a free account you get 20 files a day, each up to 500 MB.
Can I cut a recording at the same time?
Yes. Press Trim on the file and choose the part to keep; only that part is converted.
Is Filebender free?
Yes, with a free account: 20 files every day (up to 2 of them videos), each up to 500 MB, with no watermark and no ads. Make the account with Google or your email address. Files converted on your device count the same way as the rest. If you need more, a Day, Week or Month Pass is one payment that never renews; see the Pricing page.
What happens to my files?
It depends on the file. Pictures your browser can convert itself, and everything you do with the PDF tools, from merging and splitting PDFs to putting photos into one, are handled on your device and never leave it, unless you choose to send a file to Filebender's servers. They still need your account: Filebender receives only their type and size, to count them against your plan like any other file. Everything else is converted on Filebender's servers on Google Cloud and deleted an hour after the conversion finishes, or straight away when you press “Delete files now”. Nobody looks at your files, and they're never used for anything else.
