What does the AC3 to MP4 converter do?
+
It converts a AC3 file into MP4 format.
Will the data inside my AC3 be preserved when converting to MP4?
+
Yes — the content is mapped to the MP4 equivalent. Format-specific extras that MP4 does not represent natively are omitted rather than corrupted.
Is the AC3 to MP4 conversion reversible?
+
You can convert the MP4 back to AC3 on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
What output quality should I expect from AC3 to MP4?
+
Default settings target broadcast / web quality — visually identical to the source for most viewers. For archival use, pick the highest quality option in the converter settings.
Is there a file-size limit when converting AC3 to MP4?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several AC3 files to MP4 at once?
+
Yes. Drop or pick multiple AC3 files in one upload — the converter processes them in parallel and returns a ZIP of the MP4 results. There is no need to repeat the upload step per file.
What happens to my AC3 files after the conversion?
+
Uploaded files and MP4 outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
Will my MP4 play on phones, tablets, and TVs?
+
Yes — MP4 uses modern codecs that play natively on iOS, Android, Smart TVs, game consoles, and every modern browser.
Do I need to install software to convert AC3 to MP4?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert AC3 to MP4?
+
No. AC3 to MP4 conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
Is there an API for AC3 to MP4 conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. AC3 to MP4 is one of the supported pairs.
What if my AC3 fails to convert to MP4?
+
Failures are usually caused by corrupted source files or unsupported AC3 variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
