Making PDF tools simple & free
SemPDF was built with one goal: give everyone access to professional-grade PDF tools without the complexity, subscriptions, or data privacy concerns of traditional software.
Our Mission
We believe working with PDFs shouldn't require expensive desktop software or uploading sensitive documents to unknown servers. SemPDF provides fast, secure, and easy-to-use PDF tools that run right in your browser — with zero data stored on our servers.
What We Stand For
Privacy First
Your files are processed and deleted immediately. We never store, read, or share your documents.
Fast & Free
Core tools are free forever. No signup needed. Convert, merge, split, and edit PDFs in seconds.
For Everyone
Accessible worldwide with a simple interface. Works on any device, any browser, any platform.
