PDF to Audiobook
Free to start. No card needed.
A scanned PDF is rejected with no OCR fallback. Upload a text-based PDF instead — headers and page numbers get stripped, then export M4B, MP3 or WAV.
“VocalLab AI nailed the process, and the output is better. Way better. I love the ability to steer voices and ease of adding emotions/ sighs/ coughs.”
“I can upload a Word document, select automatic casting, click a button, and out comes a fully dramatised audiobook with different voices and performances.”

A PDF exported from a word processor or ebook tool carries a text layer that analysis can read directly.Cast, generate and export
Assign voices, generate the book or selected chapters, and download an M4B with chapter markers, one merged MP3 or WAV, with a combined SRT, once the run finishes.

Heading styles and a table of contents, where present, guide where chapters break.Per-chapter export
Download individual chapters separately, useful once a book runs past a few thousand lines.M4B, MP3 or WAV output

What Can You Create with PDF to Audiobook?
From TikTok to podcasts — here's where creators use this tool most.
Manuscripts exported to PDF
A manuscript saved as PDF from a word processor keeps its text layer and narrates cleanly, headers and footers stripped.Reports with a table of contents
A formatted report PDF with heading styles gives chapter detection something to split on.Print-ready book files
A print-layout PDF prepared for a printer can double as the source for an audio edition, provided the text wasn't flattened to an image.Rescuing an old text file

About this tool
Everything you need to know about PDF to Audiobook
A PDF converts to audiobook only if the text is selectable — a scanned page, with no underlying text layer, is rejected outright with a message asking for a text-based file instead (EPUB, DOCX and a text-based PDF all work, among 10 supported formats); there's no OCR step to fall back on. Once a text PDF is in, headers, footers and page numbers get stripped from the reading so they don't interrupt the narration, and the rest runs through the same chapter detection, casting and export as any other file.

My PDF was rejected — what does that mean?
It means no selectable text was found in the file, which almost always means it's a scan of physical pages; upload a text-based file instead — an EPUB, DOCX, a text-based PDF or another of the 10 supported formats.
Is there an OCR option for scanned pages?
No, there's no OCR step here — a scanned PDF needs to be converted to real text elsewhere before it can be uploaded.
Will page numbers and headers get read aloud?
No, running headers, footers and page numbers are stripped out before narration so they don't interrupt the text.
How do I know if my PDF has real text?
Open it in any PDF reader and try to select a line — if the cursor highlights actual words, the file has a text layer and will upload fine.
Can citations or footnotes in a PDF be skipped?
Text is read from the file as it appears, so trimming footnotes or citation blocks out of the source document before upload keeps them out of the narration.
