FLAC till Opus Vanliga frågor om konvertering
How do I convert FLAC to Opus audio?
+
Upload your FLAC file and PDF.to re-encodes it into a Opus container with sensible default bitrate and sample-rate. The Opus download is ready in seconds.
Is FLAC to Opus a lossy or lossless conversion?
+
If both FLAC and Opus are lossless (WAV, FLAC, AIFF), no quality is lost. If Opus is lossy (MP3, AAC, OGG, Opus), audio is re-encoded; we default to a high bitrate (192-320 kbps) for near-transparent quality.
What bitrate does the Opus output use?
+
192 kbps by default for Opus where applicable. Use the options panel to pick 96, 128, 192, 256, or 320 kbps depending on whether you want smaller files or higher fidelity.
Are tags (artist, title, album) preserved when converting FLAC to Opus?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when Opus supports it.
Will sample-rate and bit-depth survive the FLAC to Opus conversion?
+
Ja som standard. Vi lägger inte ner sample eller dither om du inte ber om det i alternativpanelen. För röst kan du välja 22 kHz mono för att krympa filstorleken.
Can I convert a stereo FLAC to mono Opus?
+
Ja — Växla alternativet force mono. Det är användbart för podcasts och röstmemos för att ungefär halvera filstorleken.
Does PDF.to support multi-channel (5.1, 7.1) FLAC files?
+
Yes for Opus formats that support multi-channel (AC3, FLAC, Opus). For stereo-only targets, multi-channel audio is downmixed using a perceptually weighted mix.
Can I batch-convert FLAC files to Opus?
+
Yes. Drop a whole folder of FLAC files; each becomes a separate Opus and all are zipped for download.
Is the FLAC to Opus converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
Does the converter remove DRM from FLAC files?
+
Nej. PDF.to försöker inte ta bort DRM. Konverteringar lyckas bara på oskyddade källfiler.
Will the Opus I download play on iPhone, Android, and desktop?
+
Yes. Opus is supported natively across all major platforms or via universally available codecs. We default to the most-compatible Opus profile.
Are my FLAC files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the FLAC and Opus files are deleted within an hour.
