Frequently Asked Questions
What video formats can I convert to MP3?
MP4, MOV, AVI, WebM, MKV, and other common video formats. The tool extracts the audio track and encodes it as MP3.
Can I choose the MP3 bitrate?
Yes. Choose 128, 192, or 320 kbps with optional title/artist tags. Free extractions are limited to 3 per day (Pro unlimited); files up to 250 MB each.
Does the conversion reduce audio quality?
Quality depends on the bitrate you choose. 320kbps produces near-original quality. Lower bitrates reduce file size but may introduce audible artifacts.
Is there a maximum video file size?
Files up to 250 MB each — larger uploads are refused before processing starts. Files near the cap still need plenty of free RAM and may process slowly on older devices.
Can I convert videos offline?
Yes. After the initial page load, the converter uses FFmpeg WASM running locally. No internet connection needed during conversion.
