Overview
Description

OCRmyPDF adds an OCR text layer to scanned PDF files, making them searchable. The original page images are kept intact and the recognised text is placed underneath them, so the document looks unchanged while its contents can be searched, selected and copied. It runs from the command line using the Tesseract OCR engine.

Sejda is a browser-based and desktop PDF toolkit offering more than 30 tools for editing, merging, splitting, compressing, and converting PDF documents without installing heavy software. It supports fill-and-sign workflows, password protection, OCR for scanned files, and batch operations like Bates numbering.
