Simple and focused

OCR PDF without installing software

Recognize English text in scanned documents while keeping unselected pages in the output. Processing can take time on large PDFs, so the tool shows page progress and an estimated time left.

Use OCR when English words are visible in a scan but cannot be selected or found with search. It creates a text layer so other tools can extract recognized words. A scan that is already searchable may not need another OCR pass.

Before you start

Rotate sideways pages first and check that the source is legible. Test one representative page before committing to a long document. Choose page positions such as 2, 5-7; unselected pages remain in the output.

Built for everyday PDFs

What this tool gives you

  • ✓English OCR with page-range selection
  • ✓Live page progress and estimated time left

Practical example

Try recognition on a non-private scan

  1. Download the English scan practice file from Guides.
  2. Run OCR on page 1 and wait for the final PDF, not just the recognition percentage.
  3. Open the output and search for BLUE FOLDER, then copy the sentence containing the number 4827.
What to expect

The output should allow searching and copying the printed English text. Compare the recognized number with the visible scan; OCR can make mistakes.

Capabilities and limits

  • Recognition supports English only. The site's interface language does not change the OCR language.
  • Handwriting, skew, blur, tiny type, columns, or complex tables can produce errors. OCR is not guaranteed transcription.
  • Processing time depends on page images and device performance. The estimate updates from completed work and can change; the final PDF still needs to be built.

When the result is unexpected

It stays in preparation for a while

First use downloads the recognition engine and English language data. Check connectivity and allow the tab to remain open.

A large file takes too long

Try a smaller page range on the original. Close memory-heavy tabs and avoid starting several OCR jobs at once.

Check the downloaded file

Search an unusual phrase and inspect copied dates, amounts, and reference numbers. Keep the scan as the visual source of truth and correct extracted text before relying on it.
