About the AC3 format
AC3 (Dolby Digital) is the surround format of the DVD era and still the standard audio track on Blu-rays and broadcast TV. It carries 5.1 channels at 384–640 kbps — built to make home theatre rumble. Extracted from discs or remuxed downloads, .ac3 files are common on everyone's drive.
Phones and most editors do not decode it. The practical move is conversion: MP3 for listening, WAV when the audio is destined for editing. Both keep the mix you know — just in a format every device handles.
+ Strengths
- ✓True 5.1 surround from disc sources
- ✓The DVD/Blu-ray audio standard
! Limitations
- −Almost no mobile or web support
- −Lossy — downmixing loses the surround image

Frequently asked questions
Is this PAF to AC3 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for PAF to AC3?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I convert a whole folder of PAF files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
Will converting PAF to AC3 reduce audio quality?
If AC3 is lossless, the output contains everything the PAF file contains — no further loss is added. If AC3 is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
