Scanned PDF to text

Give it PDF links and get the text of every page, with a status and confidence score per page.

Run it on the Apify Store

The job

Each PDF page is rendered at the resolution you choose (pdfDpi, default 200) and read with Tesseract, so scanned documents without a text layer become text. You get one row per page with status (ok, no_text, unreadable, too_big or fetch_failed), Tesseract's mean word confidence and the text; optional lines and markdown output.

Example input

{
  "files": ["https://example.com/scan.pdf"],
  "languages": ["eng"],
  "minConfidence": 0.5,
  "maxPages": 200,
  "pdfDpi": 200
}

Example output

{
  "source": "https://example.com/scan.pdf",
  "page": 1,
  "status": "ok",
  "confidence": 0.93,
  "language": "eng",
  "text": "..."
}

Good to know

• Every PDF page is rendered and read as an image; an existing text layer is not used, so for PDFs that already contain text a text extractor is quicker and exact.
• Confidence is Tesseract's own estimate, not a measure of accuracy. Handwriting and low-resolution scans read poorly; no tables or layout analysis.
• About 2.5 seconds per page on the platform, so 200 pages take about 8 minutes.
