Questions about OPUS to OGG

Is converting OPUS to OGG free?
Yes, one file at a time: the converter on this page runs in your browser, files up to 100 MB, no sign-up. The Filoshi desktop app ($29 once, for Windows) converts many files at once and has no size limit.
Does converting OPUS to OGG lose quality?
Yes, a little. OGG is a lossy format, so some detail is thrown away when the file is saved. Filoshi uses a high-quality setting by default, and you can choose the bitrate in the file viewer. OPUS is lossy too, so this is a second round of compression; convert from the original, not from earlier conversions.
Is my OPUS file uploaded anywhere?
No. The converter on this page runs in your browser with FFmpeg compiled to WebAssembly; your OPUS file is read and converted on your device and never sent to a server. The desktop app works the same way, offline.
Has OPUS to OGG been tested?
Yes. OPUS to OGG is one of the 1,841 conversions that passed Filoshi's automated test matrix on Windows 11.
Can I convert many OPUS files at once?
Yes, in the desktop app. Drop as many OPUS files as you like on the window, pick OGG once for all of them, and each file shows its own progress. The new files appear next to the originals, which are never changed.
