Quick answer: To convert RA to AC3, add the RA file to the iHateFiles RA to AC3 converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. RA is a format most software has stopped opening. AC3 is not.
Should you convert RA to AC3?
A safe conversion: RA and AC3 are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
RA and AC3 are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the RA. These recordings were made for modems. Converting keeps them alive but cannot make them sound better than they were captured.
About the AC3. Playing a 5.1 AC3 track on stereo speakers can leave dialogue almost inaudible, because the centre channel carrying it is not being mixed in. Downmixing to stereo during conversion fixes that.
How to convert RA to AC3
- Add your RA file. It is read from your disk and stays there.
- Check the settings. The output format is already set to AC3.
- Press convert and the AC3 file is saved back to your device.
Questions
How do I convert RA to AC3?
Open this page, add your RA file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this RA to AC3 converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to AC3 lose quality?
AC3 is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several RA files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
