WEBM to MP3 FAQs
Is my WEBM file uploaded anywhere?
No. Conversion happens entirely in your browser. Your file never leaves your device.
What about audio-only WEBM files?
They work too. If your WEBM contains only audio (like a voice recording), we’ll convert it to MP3 just the same.
Which quality should I choose?
192 kbps is the best all-rounder for music. Use 128 kbps for voice to keep files tiny, or 320 kbps if you want the highest quality.
What’s the maximum file size?
200 MB. For the smoothest experience, keep files under 100 MB.
