123 PDF Editor PRO for Windows

Edit text on PDF documents, sign, protect, compress and create PDF file

123 PDF Editor PRO is a complete PDF workspace that runs directly on your Windows computer. Edit text and images, build and fill forms, run OCR, sign, organize pages, protect and compress — all without a single file ever leaving your machine. No account, no cloud, no uploads.

Unlike online PDF tools that send your documents to a server you can't see, 123 PDF Editor PRO performs every operation locally on your PC. Contracts, IDs and financial documents stay confidential by design, and the app works even with no internet connection at all.

Everything a PDF needs, in one application:

• Edit text in place — click any paragraph and type; the editor auto-matches the original font, size and colour, with 13 bundled fonts and full formatting.

• Replace and reposition images — move, resize, swap or remove any picture, and insert new images, tables and signatures.

• Local OCR — turn scanned pages into editable text in 10 languages, entirely offline, with automatic detection.

• Forms — fill existing forms or create text fields, checkboxes, dropdowns and buttons.

• Page organizer — reorder, rotate, duplicate, crop and resize pages by dragging.

• Merge & split — combine multiple PDFs or extract pages any way you like.

• Signatures — add image signatures or apply a certificate-based digital signature.

• Annotations & comments — sticky notes, highlights, shapes and review marks that stay editable.

• Watermarks & decoration — headers, footers, page numbers, watermarks and backgrounds.

• Protection & privacy — AES-256 or RC4 encryption with user and owner passwords, fine-grained permissions, and one-click removal of metadata, JavaScript and hidden data.

• Compress — shrink file size with Web, Email or Print profiles, locally.

• Templates, tables & search-and-replace — start from 16 editable page templates and find/replace text across the whole document in one pass.

Try everything, upgrade once. Every tool works in the free version — PRO simply removes the usage limits (unlimited clean downloads and saved projects, OCR export without the Free banner) for a single one-time payment. No subscription.
