About Open PDF Toolkit
Open PDF Toolkit is a set of free PDF tools: merge, split, rotate, sign, fill in forms, add page numbers, and more.
Every tool runs in your web browser. Your files are opened and changed on your device, so they are never uploaded, and there's no account and no waiting in a queue.
Big jobs use your device's own processor and memory. On a phone, very large files can take longer than on a computer; the tools tell you before you start.
Who runs it
Open PDF Toolkit is run by BookCricket Operations LLC and is free to use. Questions, corrections, or ideas: hello@openpdftoolkit.com.
