Audio inputs and Apple-focused outputs
Common inputs include MP3, WAV, M4A, AAC, FLAC, and OGG, subject to browser decoding support. This page exports M4A and M4R. Renaming an MP3 file to .m4r does not convert the audio.
Local files and network imports
Files selected from your device are decoded, edited, and rendered in your browser. Dropbox, Google Drive, and public-link imports involve network requests. The encoder may need to download before the first export.
Keep the original recording
Large source files can use substantial memory even when the selected clip is short. Start with a manageable recording, keep the original, and download the result before closing the page.
Setup depends on the device
The guide below the tool follows Apple’s GarageBand workflow. App availability and menus depend on your iPhone and software version. This page does not promise automatic installation or identical sharing options on every iOS version.
