Frequently asked questions
Can I convert video files to MP3?
Yes. Drop any video file (MP4, MOV, AVI, MKV, WebM) and the tool will extract the audio track and convert it to your chosen format — WAV, MP3, µ-law or A-law.
Is there a file limit?
No. You can convert as many files as you like in a single session. All processing happens locally in your browser.
What sample rates and bit depths are supported?
You can resample to any standard rate (8 kHz to 96 kHz) and output in 16-bit. The original sample rate is preserved by default.
Are my files uploaded anywhere?
No. AudioQC processes everything in your browser using the Web Audio API. No files leave your machine.
