Frequently asked questions
Which MP3 quality should I choose?
192 kbps is a great balance for music and voice. Choose 320 kbps for maximum quality or 128 kbps for a smaller file.
Is there a file size limit?
No limit is imposed. For videos over 500 MB a computer is recommended because conversion uses your device's memory.
Can I convert a YouTube video?
The tool converts files stored on your device; it does not download videos from YouTube.
What is the maximum size?
There is no fixed limit; videos over 1 GB may be slow on older phones.
Is this tool really free?
Yes, 100% free, with no sign-up, no watermark and no usage limit.
Are my files safe?
Yes. Processing happens directly in your browser: your files are never uploaded to a server or stored.
