Private PDF tools that don't upload your files
Every time you upload a document to an online PDF service, a copy sits on someone else's server — for minutes, hours or longer, under rules you never read. For passports, payslips, medical letters and contracts, that's a real risk.
ShamsPDF takes a different approach. Most of our tools run entirely in your browser: merge, split, compress, rotate, organize, sign, watermark, page numbers, edit, fill forms, compare, extract pages and many more. The file is processed on your own device and never sent anywhere. The tool you see below is Merge PDF — try it and check your browser's network activity: there's no upload.
A few conversions, such as Word to PDF and OCR, genuinely need a server. Those are clearly marked Secure server, and for them: files are encrypted, deleted right after download, and never kept longer than 10 minutes. We never look at, share or keep copies of your files.
No sign-up, no watermarks, and nothing to install.
The options for this task are already set. You can still change them after adding your file. Open the full Merge PDF tool
