Free PDF to podcast
Turn a PDF into audio free — with the extraction checked first.
Upload a PDF up to 20 MB, review the text that survived extraction, edit the script, then generate narration or a two-host conversation. New accounts get 50 trial credits valid for 30 days.
What the trial covers
One PDF, start to finished MP3.
The trial is an allowance of credits rather than a limited demo, so a focused document can go all the way to a downloadable episode.
50 credits, 30 days
Enough for one focused PDF episode: extract, outline, edit, and generate. The allowance does not renew, so choose the PDF that matters most.
PDF, DOCX, TXT, Markdown
Export the chapter you need rather than uploading a whole book. A 20 MB limit applies per file, and a cleaned text file usually extracts better than a designed PDF.
Narration or conversation
Produce a single-narrator reading or a two-host discussion from the same source. Up to four speakers are supported if you want a panel.
Editable before synthesis
Nothing is generated until you approve the script. This matters more for PDFs than for any other source, because layout-driven content is where extraction breaks.
PDF-specific checks
Four things PDFs break that other sources do not.
A PDF stores layout, not reading order. These are the failure points to inspect before you spend credits on audio.
Scanned pages
OCR may be attempted when very little text is recovered, but it is not guaranteed. If a page is an image, run OCR in your document tool and upload a searchable PDF.
Tables and charts
Column relationships disappear in plain text. State figures and units explicitly in the script, and check that a conclusion still reads correctly without the table on screen.
Footnotes and references
Citations usually do not survive a conversion. Keep the source list beside your script and read important attributions aloud instead of pointing to a footnote number.
Two-column layouts
Text can interleave across columns during extraction. Read the first paragraph of each section to confirm the reading order before generating audio.
How it works
From PDF pages to a downloadable episode.
- 1
Upload the PDF
Up to 20 MB, with DOCX, TXT, and Markdown accepted as alternates. Selectable text extracts most reliably; scanned pages may need OCR outside VocalVia first.
- 2
Check what was extracted
Headings, tables, and figures are the weak points of any PDF-to-audio pipeline. Compare the extracted text with the page before you trust the script.
- 3
Edit the script
Rewrite phrases that reference the layout — "as shown in the table" becomes the actual numbers a listener needs. This step is included in the trial.
- 4
Generate and download
Assign a narrator or two hosts, synthesize the episode, then download the MP3. The trial covers about 8 minutes 20 seconds of standard audio.
Frequently asked questions
Can I convert a PDF to a podcast for free?
Yes, with a fixed trial allowance. A new account gets 50 credits valid for 30 days — about 8 minutes 20 seconds of standard audio — and the full PDF workflow, including script editing, is available. After the trial, the Standard plan is $12 per month for 500 credits, roughly 83 minutes of audio.
Does it work with scanned PDFs?
Partially. OCR can be attempted when extraction recovers very little text, but results vary and image-only pages may be missed, especially in files that mix selectable text and scans. The reliable path is to run OCR in your PDF tool first, verify the text, then upload a searchable file or a plain text version.
How long can the resulting episode be?
There is no fixed minute cap; the limit is your credit balance. A trial of 50 credits suits a short episode of roughly 8 minutes of standard audio. Longer PDFs need either a tighter script focused on the key sections or a paid plan with more credits.
Will the PDF figures and tables be read correctly?
Do not assume that. Visual relationships are lost in plain text, so numbers can end up without units or a table can read as a list of loose values. Compare the script with the page, rewrite chart references as spoken sentences, and keep the caveats attached to each conclusion.
Can a PDF become a two-host episode instead of narration?
Yes. Choose a multi-speaker format, review the generated roles, and assign a different voice to each host. A conversational format often works better for reports with several findings, because one host can raise the objection the document answers later.
What happens if my PDF has no selectable text at all?
Extraction returns almost nothing, so there is little for the script stage to work with. Convert the file with an OCR tool first, check that headings and paragraphs came through in the right order, and upload the result as a searchable PDF or a text file.
