What is PDF.dk?
PDF.dk is a collection of over 40 free tools for working with PDF files, all hosted on servers in Denmark with privacy as a core principle. The toolset covers common PDF tasks: merging, splitting, compressing, converting to and from other formats, adding watermarks, and extracting text or images. There are no account requirements for basic use, and files are not stored on servers longer than necessary. This makes it suitable for users who need occasional PDF work without signing up for accounts or paying subscription fees. The Danish hosting means your files benefit from GDPR compliance and strong data protection standards by default.
