Free PDF OCR Tool – Extract Text from Scanned PDFs

OCR stands for Optical Character Recognition. It is technology that reads text from images and scanned documents by analyzing the shapes of letters and matching them to characters, converting a picture of text into machine-readable, editable, and searchable text that you can copy or save.

The OCR supports English, Hindi, and many other languages, so it works on a wide range of documents. Accuracy depends on the scan quality and how clearly the characters are printed. For the best results with any language, use a sharp, high-resolution, evenly lit scan of the page.

For clear, high-resolution scans with straight, evenly lit printed text, accuracy is typically above 95%. Accuracy drops on blurry photos, faint print, skewed pages, or unusual fonts. It is good practice to proofread the output, especially names and numbers, where a single misread character can matter.

Scan or photograph the page at a higher resolution, keep it flat and square, and use even lighting without shadows or glare. Clean, sharp, well-aligned text recognizes far better than blurry or skewed images. Standard printed fonts also work better than decorative fonts or handwriting.

OCR is designed for printed and typed text, where it performs best. Handwriting recognition is much harder and results are usually unreliable, especially with cursive or inconsistent writing. For handwritten notes, expect to do significant manual correction, and treat the output as a rough starting point rather than a finished transcription.

Yes. The OCR runs entirely in your browser, so your scanned documents are never uploaded to a server and nothing is stored online. This is important for sensitive scans like IDs, contracts, and financial records, which remain on your own device throughout the process.

Regular text extraction copies an existing text layer from digital PDFs and fails on scans because there is no text layer to read. OCR instead recognizes characters from the image itself, so it can pull text out of scanned or photographed pages that plain extraction cannot handle at all.

Yes. The tool works in mobile browsers on Android and iPhone, so you can photograph a document, convert it to a PDF, and extract its text on the same device. This is handy for digitizing receipts or notes on the go, though clear, well-lit photos still give the best accuracy.
