Frequently asked questions
Which format should I choose?
MP3 to play anywhere; M4A (AAC) for Apple devices; WAV for a lossless file to edit in software; OGG (Opus) for the smallest file at the same quality.
Can I convert an iPhone voice memo?
Yes: voice memos are M4A files. They convert to MP3 in every browser that can read AAC (Chrome, Edge, Safari).
Are my files uploaded?
No, the conversion happens in your browser.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
