When M4A isn't enough
Instagram serves audio as M4A, and most modern apps play it fine. But car stereos, older editors, WhatsApp-status makers and sample libraries often want a real .mp3 — so this tool actually re-encodes, instead of renaming the file and hoping.
FastDL's audio USP, done better
Competitors advertise “MP3 download” and hand you an M4A with a changed extension. Ours is the genuine article: decoded, re-encoded at 192 kbps, with a live progress bar — all client-side, all free.
