OCR FAQs
What is OCR?
Optical character recognition turns scanned images or image-PDFs into selectable text using Tesseract in your browser.
Is OCR private?
Yes. OCR runs locally — scans are not uploaded.
Which languages work?
Depends on the Tesseract language data loaded in the tool; English is the common default.
Do you upload my files?
No. GroundPDF processes files entirely in your browser with WebAssembly. Files never leave your device — nothing is uploaded to a server.
Is it free?
Yes. Free to use with no account and no daily limits.
Which devices and browsers work?
Any modern browser with WebAssembly support: Chrome, Firefox, Safari, and Edge on desktop or mobile.
How is this different from iLovePDF or Smallpdf?
Those tools upload your files to the cloud. GroundPDF runs on your device (on the ground, not in the cloud), so your documents stay private by design.
