More DSS conversionsDSS to M4A is coming soon
We list every conversion we plan to support so you can find it later, but we only switch one on once it really works. APE, DSS and SHN can be read but not written.
M4A – MPEG-4 Audio
M4A is an MP4 container for audio, normally AAC. It is the default audio format for iTunes, iPhone voice memos and many podcasts.
More M4A conversionsHow this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
