Read the full guide with screenshotsWhat is M4A?
M4A is AAC audio in an MPEG-4 container, used by Apple Music, iTunes, Voice Memos and many phone recorders.
What is OGG?
OGG is an open audio container, usually holding Vorbis or Opus audio. It is used by games, Android, Discord and WhatsApp voice notes, but Apple devices and many players can’t open it.
Is it private?
Yes. Unlike upload-based converters, ZapMorph processes files inside your browser tab, so the file stays on your device. It is never transmitted, stored or logged — close the tab and it’s gone.
Frequently asked questions
Is the m4a to ogg converter free?
Yes, once a day. Convert one file up to 25 MB a day without an account. A free account gets one run a day on any Pro tool with files up to 50 MB; Pro and Lifetime plans are unlimited.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.
What is the maximum file size?
Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.
Can I convert multiple M4A files at once?
Yes. Select several M4A files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.
Does it work on Mac, Windows, iPhone and Android?
Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
