Conversion settings
Choose settings before adding files. The same settings apply to the whole batch.
Lossy conversion cannot restore detail missing from the source. Compression presets for lossless formats change file size and processing time, without reducing sound quality.

Extract AC3 audio from MPEG video
Convert the first audio stream to AC3 without video. This is lossy audio encoding, not a recovery of missing surround channels. AC3 playback is not supported by every browser: download it and check it in a compatible player.
Keep the original and choose a readable file.
Wait for the completed conversion, then download or preview the result.
