Compress Audio for scanned documents specifically
Scanned audio files come out unnecessarily huge by default. Compress Audio brings them down dramatically without losing the text.
If you've ended up here, you have a audio file and a specific job: scanned document. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.
Launch the tool: Compress Audio — Browser-only. Nothing is sent to a server.
Why scanned document needs different settings
A audio file for scanned document optimises for things the original audio file doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.

- Drop the audio file on the input area.
- Choose settings appropriate for scanned document — see the recommendations in the next section.
- Run the processing. It happens locally in your browser tab.
- Download and verify. Quick visual check before you send.
Recommended settings for scanned document
Scanned audio files are notorious for size bloat. The right move is to keep the text crisp while aggressively compressing the surrounding white space and the embedded thumbnail. Compress Audio handles both in a single pass.
Run it in your browser
Everything happens locally in your browser — your file never leaves your device.
What to verify before sending
Quick check-list once Compress Audio finishes:
- Open the result. Make sure it looks right at the size the recipient will actually see it.
- Check the file size. Match it against the limit you're targeting.
- Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects
.jpgwon't necessarily accept.jpeg. - Send a test to yourself first. Open the test on the same device the recipient will use, if you can.
Frequently asked questions
Can I undo the compression later?
No — compression is one-way. Always keep the original audio file archived somewhere, and treat the compressed version as a send-only copy.
Will Compress Audio work for a batch of audio files?
Yes — drop multiple files at once. All of them get the same scanned document settings applied, then downloaded as a folder.
Is Compress Audio safe for sensitive audio files like a resume or visa documents?
Yes — every step happens locally in your browser. The audio file never leaves your device because there is no server in the loop.
What if the recipient asks for the original?
Keep the original. Compress Audio produces a copy; the source file you dragged in is never modified.
