Pro export FAQs

How are exports kept spec-conformant?+

Each exporter validates against the format spec before download — VTT cue ordering, SRT line numbering, ASS section structure, JSON schema.

Are character encodings handled correctly?+

UTF-8 for everything that isn't DOCX (DOCX uses its own native encoding). BOM is omitted from SRT to stay player-compatible.

Can I export multiple formats in one click?+

Yes. Select any subset and Pxlify bundles them as a zip.

Is the export tool free?+

Yes. Exports are free; Pxlify Pro lifts the file-size and length caps on the underlying transcription.
