How to turn scanned pages into text you can actually search

Scanned PDFpages = pictures, no text layerOCR PDFruns in your browserSearchable textcopy · search · paste300 DPI · straight · high contrast

If you can't select text in a PDF, there is no text — the pages are photographs. Search, copy and screen readers all come up empty. OCR adds the missing text back.

Step 1 — Confirm what you have

Drop the file on OCR PDF. The inspection card samples the pages: "looks scanned" confirms there is no text layer to extract, so plain PDF to TXT would return an empty file. (If the card says the file has a text layer, stop — PDF to TXT will get you perfect text in a second, no OCR needed.)

Step 2 — Run OCR, in the browser

Convert. The OCR engine (Tesseract) downloads to your browser on first use — around 19 MB, cached afterwards — and reads each page. Your scan never leaves the tab. Expect a few seconds per page; the per-page progress is shown live.

Step 3 — Proofread the three classics

Modern OCR is excellent but not clairvoyant. Before trusting the output, check the places it actually fails: numbers (0/O, 1/l, 5/S), names, and columns/tables (reading order can jumble them). One quick pass catches what matters.

What drives accuracy — honestly

  • Resolution: 300 DPI scans read dramatically better than 150 DPI phone snaps.
  • Skew: a tilted page multiplies errors — flatten and re-shoot if you can.
  • Contrast: gray-on-gray fades; crisp black-on-white shines.
  • Language: choose the English or Turkish model before recognition; text in other languages may be misread.

Photographs of single pages work too — Image to Text is the same engine for JPG/PNG/screenshot input.
