An offline alternative to online PDF tools (merge, compress, password)

Merge, split, compress, rotate, watermark and password-protect PDFs without uploading contracts or bank statements to a website.

Free · no account · 3 free uses of every tool · also for Mac (Intel), Windows, Linux

Online PDF sites like iLovePDF and Smallpdf are convenient — but you upload the document to do anything with it. For contracts, payslips, medical letters or anything with an ID number, that is an unnecessary risk, and many sites limit how many files or tasks you get for free.

What you can do offline

• Merge several PDFs in the order you choose.
• Compress a PDF before emailing it or uploading it to a portal.
• Add or remove a password (AES-256).
• Split, extract pages, rotate scans and watermark (“DRAFT”, “CONFIDENTIAL”).

Or ask your AI
