About Converting SUB to PDF
Converting a SUB (.sub) file to PDF turns MicroDVD's frame-numbered subtitles into a readable, printable transcript page: ready to print, archive, or share with anyone who doesn't have a subtitle editor.
What is MicroDVD (SUB)?
MicroDVD (.sub) is a frame-based subtitle format that times each line by frame number rather than by clock time. It is common with older desktop and DVD players.
What is a PDF Subtitle Transcript?
A PDF transcript export is a print-ready, shareable document version of a subtitle file (each cue's timestamp and text laid out as readable paragraphs, the way a script or transcript reads on paper. It is rendered as an image-based PDF (not selectable/searchable text) so every language's script) including Arabic, Thai, and Chinese/Japanese/Korean, displays correctly regardless of which fonts are installed on the reader's device.
About SUB to PDF Conversion
- One readable page per stretch of cues: timestamps and cue text are laid out as a document, not a data table, the same way a script or transcript reads on paper.
- Rendered as an image, not selectable text: every cue is drawn using your browser's own font rendering (so Arabic, Thai, Chinese, Japanese, and Korean subtitles all display correctly), which means the exported PDF is a print-ready image of the transcript, the text in it is not searchable or copy-pasteable the way it would be in a text-based PDF.
- A4 or Letter, your choice: pick the page size that matches how you'll print or read the document.
- Frame numbers converted to real timestamps first: MicroDVD's frame-based timing is converted to milliseconds using the detected or selected frame rate (23.976 by default) before the transcript is laid out, so the printed page shows real times, not raw frame counts.
Timecodes are converted to PDF timing precision with no loss of sync.
What You Lose vs What You Gain
What You Lose in Conversion
- Frame-number timing (tied to the video frame rate)
What You Gain in Conversion
- Formatted to print cleanly on A4 or Letter paper, ready to hand out or archive
- Displays correctly in any PDF viewer, on any device, in any of the site's 22 languages, no font installation needed
- A clean, readable document to share with a director, client, or translator who doesn't need a subtitle editor

Frequently Asked Questions
Can I edit the PDF and convert it back into a SUB file?
Not with this tool: PDF export is one-directional. It's meant for printing, archiving, or sharing a readable transcript, not as a round-trippable subtitle format. Keep your original .sub file if you need it back.
Why can't I search or select the text in the exported PDF?
The PDF is rendered as an image of each page rather than as selectable text. This is a deliberate trade-off: rendering as an image lets every subtitle in any of the site's 22 languages (including Arabic, Thai, and Chinese/Japanese/Korean) display with correct letterforms using your own browser's fonts, without needing to embed and ship extra font files. If you need searchable text, use the JSON or CSV export instead.
Will the timestamps on the PDF be accurate if my SUB file has no FPS marker?
Only if your file actually runs at the default 23.976 fps. MicroDVD stores frame numbers, not time, and this tool assumes 23.976 fps when the file's first line doesn't carry an explicit FPS marker. If your source video uses a different rate (25 fps for PAL is common), select it before converting or the printed timestamps will be off.
Tips for Converting SUB to PDF
PDF export is one-way: there is no PDF-to-SUB converter, since PDF here is a printable/shareable document format, not a subtitle format any player reads back.
Know your FPS! If the printed timestamps look off, your file likely uses a different frame rate than the 23.976 default, check with VLC (Tools → Media Information → Codec Details) or MediaInfo and select the correct rate before converting.
If you need to search or copy text from the transcript, keep the original SUB file (or use the JSON/CSV export instead), the PDF's text is rendered as an image for correct multi-script display, not as selectable text.
