About QuickAudioConvert
A free tool for converting audio files between common formats. No account required. No software to install. Files deleted automatically after 30 minutes.
What it does
QuickAudioConvert converts audio and video files between formats. Upload a file — MP4, WAV, FLAC, M4A, MP3, AAC, OGG, OPUS, WMA, or AIFF — choose an output format, and download the result. Conversion runs server-side using FFmpeg, so nothing is processed in your browser and nothing installs on your device.
Output formats are MP3, WAV, M4A, FLAC, AAC, OGG, and OPUS. The converter shows which outputs are available for the file you upload — not every combination is offered (FLAC output, for instance, is only shown for uncompressed sources like WAV and AIFF). Files up to 200 MB are supported.
Why it exists
Most audio converters online are not really converters — they are download funnels, ad networks, or subscription prompts that happen to convert files on the side. The ones that do work tend to be cluttered, slow to load, or vague about what happens to your files after you upload them.
This tool exists to be the straightforward alternative: no account wall before you can use it, no upsell after you do, and no ambiguity about data handling. You upload a file, get a converted file back, and that is the entire interaction.
That same reasoning shapes the rest of the site. The guides and learn articles exist because a lot of people converting files are also trying to understand what format to convert to, why their file sounds different after, or what bitrate actually means. It seemed worth explaining that clearly rather than leaving people to piece it together from forum posts.
Who it is for
Anyone who needs to convert an audio file without signing up for a service or installing software. Common use cases:
- —Extracting audio from a video file (MP4 to MP3)
- —Compressing a large WAV file for sharing or uploading
- —Converting a FLAC or M4A file so it plays on a device that does not support it
- —Getting an MP3 into WAV format for use in audio editing software
- —Converting a voice recording, podcast file, or downloaded video clip
How files are handled
Files are uploaded to our server only to perform the conversion. Both the original and the converted output are automatically deleted within 30 minutes — whether you download them or not. We do not read, analyse, share, or retain your files beyond what is needed to process your request.
Files are stored using randomised identifiers that are not publicly guessable. No account is created, no email is collected, and no file metadata is logged permanently. For full details, see the Privacy Policy.
Limitations
These are real constraints, not hedging. Worth knowing before you upload:
- —Maximum file size is 200 MB per upload.
- —FLAC output is only available when converting from an uncompressed or lossless source (WAV, AIFF). Converting a lossy file like MP3 to FLAC produces a large file with unchanged lossy quality — so that option is not offered.
- —Converting from an already-compressed format (e.g. MP3 to WAV) does not restore quality lost during the original compression. The file will be larger, not better.
- —Files must be downloaded within 30 minutes of conversion. After that, they are permanently deleted.
- —Rate limiting applies: up to 10 requests per minute per IP address.

QuickAudioConvert is an actively maintained project. The format pages, guides, and learn articles are updated when formats change or something turns out to be unclear. If a conversion is not working as described, the Contact page is the fastest way to flag it.
