PDF Tools
Merge, split, compress, edit and sign PDFs. 35 free tools.
Free PDF tools that work on any device
These tools cover the jobs people do with PDFs every week: putting files together with Merge PDF, pulling pages out with Split PDF, fixing the order in Organize PDF and turning a phone photo into a document with JPG to PDF.
If a portal rejects your file for being too large, Compress PDF shrinks it, and the fixed targets such as 100 KB or 1 MB aim for a specific limit. To change what is on the page, use the PDF Editor, Fill PDF Form or Add Page Numbers.
Where your files are processed
Most PDF tools run inside your browser, so the file stays on your device. Strong compression, OCR, PDF/A, repair and password tools need server software; those files are sent over HTTPS, processed and deleted automatically. Unlock PDF only removes a password you already know. It never guesses or cracks passwords.
