Are my files uploaded to a server?

No. 7minti runs entirely in your browser. Your MP4 never leaves your device unless you copy the exported MP3 yourself.

What file formats does 7minti support?

Input: MP4, M4A, and M4V. Output: MP3 at 320 kbps stereo or 192 kbps mono, matching the source channel layout.

Can I trim audio before converting to MP3?

Yes. Select a queued file, set in and out points on the waveform, then convert only that time range.

Is there a file size limit?

Yes. Each file can be up to 5 GB. Very large files may require a desktop browser with enough RAM.

Will the MP3 sound exactly like the MP4?

MP3 is lossy, so it is not bit-identical. 7minti avoids loudness compression and passes decoded audio through to keep voice and music close to the source.

Which browsers work best?

Chromium-based desktop browsers (Chrome, Edge, Brave) with Web Codecs and the File System Access API provide the full streaming save path.

Does 7minti cost money?

No. 7minti is free to use. There is no account, subscription, or per-file fee.

Creators, editors, podcasters, and anyone who needs MP3 exports from MP4 without cloud uploads or privacy risk.
