Frequently asked questions
Can I cut an M4A file from my iPhone?
Yes. Voice Memos and most recorder apps save M4A files, which open here directly. Save the result as MP3 for sharing, or WAV for editing.
Is there a file size limit?
Files up to about 1.5 GB can be opened. There are no daily limits.
Do I need to install anything?
No. It works in Chrome, Safari, Edge and Firefox on computers and phones.
