Merge PDF
Merge PDF online free without handing your documents to a stranger's server. Select two or more PDFs, press Merge, and download one combined file. The files are joined inside your browser in the order you selected them.
🔒 Your files never leave your device.
How to use
- Select all the PDF files you want to combine.
- Check the file names shown — pages will be added in that order.
- Press Merge PDFs and download the combined file.
How it works
When you press Merge, a small open-source PDF library (pdf-lib) is loaded on demand and runs entirely in your browser tab. Each source PDF's pages are copied into one new document. Nothing is uploaded, stored or tracked.
Worked example: Example: combine a CNIC scan PDF, a degrees PDF and an experience letter PDF into one file for a job application portal that accepts a single upload.
Frequently asked questions
Is it safe to merge private documents here?
Yes — the merging happens on your device. Your PDFs are never uploaded to a server, so bank statements, ID documents and certificates stay private.
In what order are the PDFs merged?
In the order the files are listed after selection. On most phones and computers that is the order you tapped them.
Is there a limit on file size or pages?
Only your device's memory. Typical application documents (a few MB each) merge quickly.
Why did merging fail?
A file may be corrupted, password-protected, or the PDF library could not load because of a connection problem. You will see a clear message — fix the file or connection and try again.
