How accurate is the OCR?

Clear, straight scans of printed text are usually recognised almost perfectly. Accuracy drops with blurry photos, handwriting, very small print or decorative fonts.

Choose "High" accuracy for small print, and straighten crooked scans with Deskew PDF first. The recognised text can also be downloaded as a .txt file to check it.

Tip: Scanning a document to OCR? 300 DPI in black and white or grey gives the best results.

Your files stay on your device

Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.

Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.
