REFERENCE / FORMATS

Supported formats and practical limits

Format support depends on the media decoders built into your browser. Current Chrome, Edge, Firefox, and Safari versions give the best results.

Convert to MP3

The dedicated tools support browser-readable video files, MP4, MOV, M4A/AAC, WAV, and FLAC sources.

WAV and FLAC are the most predictable audio inputs.
MP4 and MOV work when their audio codec is supported by the browser.
Protected or DRM-controlled media cannot be converted.

Available converters

Dedicated pages accept browser-readable general video files, MP4, MOV, M4A/AAC, WAV, and FLAC sources and create MP3 output.

File size and device memory

Each selected file is limited to 100 MB, and a batch can contain up to 10 files. Conversion also uses device memory, so available capacity still varies by browser and device.

When a file does not open

Try an up-to-date browser or export the source with a standard codec. The original file is never changed by this site.
