- When you convert two or more files, the results are bundled into a single ZIP so you download everything in one click.

Frequently asked questions
Is my AAC file uploaded when I convert it to OGG?＋
No. The conversion runs entirely in your browser using your device, so your file is never sent to any server.
Will the quality drop when I convert AAC to OGG?＋
Both AAC and OGG are lossy formats, so re-encoding may slightly reduce quality.
Can I convert several AAC files to OGG at once?＋
Yes. Add multiple files and they are converted one by one in your browser. A single file downloads directly; two or more are packed into one ZIP. If one file fails, the others still convert.
Is it free? Do I need to sign up?＋
Yes, it is completely free — no sign-up, no install and no watermark.
Is there a file size limit?＋
You can convert files up to 100 MB. Everything is processed on your device, so very large files depend on your available memory.
Can I convert the other way, from OGG back to AAC?＋
That direction is not available right now. AAC can still be converted to several other formats.
