m4a to text, straight from the file
m4a is what iPhones, voice recorders, and messaging apps hand you — and most converters want you to convert it again first. Upload it as-is and get text in seconds.
m4a is the default recording format everywhere: iPhone voice memos, iPad screen notes, most Android recorders, WhatsApp voice messages. It's compact and great for storage — and useless for search, quoting, or skimming.
Drop the file here as-is. No re-encoding, no software to install, and the transcript keeps the punctuation and paragraphing that make text readable.
