Online Optical Character Recognition (OCR) tools traditionally process your documents on third-party servers. If you are handling passports, contracts, or financial statements, this is a major security risk. PDFlow implements WebAssembly ports of OCR engines that execute recognition algorithms in the browser. Your scan files remain 100% secure on your computer.
Frequently Asked Questions
