MP3 till FLAC Vanliga frågor om konvertering
How do I convert MP3 to FLAC audio?
+
Upload your MP3 file and PDF.to re-encodes it into a FLAC container with sensible default bitrate and sample-rate. The FLAC download is ready in seconds.
Is MP3 to FLAC a lossy or lossless conversion?
+
If both MP3 and FLAC are lossless (WAV, FLAC, AIFF), no quality is lost. If FLAC 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 FLAC output use?
+
192 kbps by default for FLAC 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 MP3 to FLAC?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when FLAC supports it.
Will sample-rate and bit-depth survive the MP3 to FLAC 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 MP3 to mono FLAC?
+
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) MP3 files?
+
Yes for FLAC 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 MP3 files to FLAC?
+
Yes. Drop a whole folder of MP3 files; each becomes a separate FLAC and all are zipped for download.
Is the MP3 to FLAC converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
Does the converter remove DRM from MP3 files?
+
Nej. PDF.to försöker inte ta bort DRM. Konverteringar lyckas bara på oskyddade källfiler.
Will the FLAC I download play on iPhone, Android, and desktop?
+
Yes. FLAC is supported natively across all major platforms or via universally available codecs. We default to the most-compatible FLAC profile.
Are my MP3 files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the MP3 and FLAC files are deleted within an hour.
