Open Opus on Phone

OPUS files usually store Opus audio in an Ogg container.

• Phone file apps often treat this format as unknown or hand it to a heavy desktop-style app.
• The useful first step is confirming file type, metadata, or readable content safely on the phone.
• A local browser preview avoids uploading private files to random converters.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
