Yes. No sign-up, no credit card. Free.ai gives every visitor 2,500 daily tokens — a single conversion costs about 200 tokens.
Drop your MP4 file on the upload box, click Convert to AAC, then download the result. The conversion runs server-side in seconds.
100 MB per upload. For larger files, sign up for an account and use our async queue — files up to 1 GB process in the background and get emailed when done.
Both MP4 and AAC are audio formats. ffmpeg re-encodes with sensible codec defaults — typically 192 kbps for AAC/MP3, lossless for WAV/FLAC.
Files are deleted from our server immediately after conversion. We do not retain, scan, or train on uploaded content. The download link is single-use and expires in 24 hours (7 days for signed-up users).
Yes. The conversion is a format change — we don't add a watermark, the output is yours to use anywhere, including commercial work.
No. Conversion runs entirely in your browser via our API — no software, no extensions, no plugins. Works on desktop, tablet, mobile.
Password-protected PDFs return a clear error pointing at /pdf/unlock/ — unlock there first, then re-upload here. Other format types don't support passwords.
Most conversions complete in 1-3 seconds. Large videos can take up to a minute. The progress bar updates in real-time.
Not on the public converter — but signed-up users can chain conversions in /workspace/ or write a 4-line script against our public API at api.free.ai/v1/convert/.
Yes — visit /convert/aac-to-mp4/. The reverse-direction page handles it.
Browse all MP4 converters under /convert/ — we support 350+ format pairs across image, audio, video, document, data, and subtitle categories.
