Extract Text From a Scanned PDF
OCR PDF to Text recognizes the text on scanned pages in the languages you choose and returns a plain .txt file. Pages that already contain text are copied as they are, and you can add a heading before each page.

OCR PDF to Text reads the pages of a PDF and returns a plain .txt file. Pages that have no usable text layer are rendered and recognized with Tesseract in the languages you pick; pages that already contain text are copied from the file, so a mixed document is not recognized twice.
Pick up to four languages that appear on the pages, choose whether each page gets a heading line such as --- Page 3 ---, and optionally restrict the run to a page range. Force OCR recognizes every selected page instead of trusting the existing text layer.
Limits are stated up front: up to 50 pages that need OCR per request on this site, counted after skipping pages that already have text, and files up to 500 MB. Layout is not preserved: columns and tables come out as running text, so use the table tool when the structure matters.

Questions fréquentes
- Why does my text look jumbled?
- OCR reads pages line by line. Multi-column layouts, tables and sidebars can interleave. Use a page range for single-column pages, or the table tool for tabular data.
- Is text that is already in the PDF copied or recognized again?
- Copied. In Normal mode a page with a usable text layer is taken as it is; only image-only pages are recognized.
- Can I get Markdown instead?
- Yes. OCR PDF with the Markdown result returns a .md file that keeps headings and lists where it can detect them.
- What happens with a very long scan?
- A request that needs more than the page limit is rejected with a clear message. Enter a page range and run the document in parts.
