คำถามที่พบบ่อย
Are my files uploaded to a server?+
No. Conversion happens entirely inside your browser and your file is never sent anywhere.
Can I convert back and forth repeatedly?+
Each lossy-to-lossy conversion loses a little quality. Convert once from your best source when possible.
Is there a file size limit?+
No server limits. Typical music files are effortless, and desktops handle files up to hundreds of MB.
Is it really free?+
Yes. No sign-up, no payment, no conversion limits and no watermark.
Can I pick a different output format?+
Yes — on the converter you can switch the output between MP3, WAV, FLAC, M4A and OGG.
คู่มือการใช้งาน
Why convert MP3 to OGG?
Compatibility. Some devices and apps simply won't open MP3 files — converting to OGG, with its near-universal support, fixes playback problems in most cases.
Typical cases: older MP3 players, car stereos and editors that can't read MP3.
What happens to quality and size?
Both MP3 and OGG are lossy formats, so re-encoding can introduce a tiny quality change. This tool re-encodes at a generous bitrate, keeping any difference practically inaudible.
File size stays in the same ballpark, depending on the bitrate you pick.
