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.

Частые вопросы

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.
