Merge PDF
Combine two or more PDFs into a single PDF, in the order you choose them.
Private by design: this tool runs 100% in your browser. Your files and text never leave your device, are never uploaded, and are never stored by Crazlee.
How to use
- Choose two or more PDF files in the order you want them merged.
- Click Merge PDFs.
- Download the combined PDF.
Worked example
You have Chapter1.pdf and Chapter2.pdf. Choose Chapter1 first, then Chapter2, click Merge PDFs, and you get one PDF with Chapter 1 followed by Chapter 2.
Frequently asked questions
Is Merge PDF really free?
Yes. It runs in your browser with no signup and no file upload.
Will my PDFs be uploaded?
No. The merge happens on your device. Nothing is sent to a server.
Can I merge scanned PDFs?
Yes, if they are valid PDF files. Scanned pages are kept as images inside the merged PDF.
What if a PDF is password-protected?
Password-protected or encrypted PDFs may not merge. Unlock your own file first, if you have the right to do so.
Is there a file size limit?
There is no Crazlee server limit, but very large files may be slow on older phones or computers because all work happens in the browser.
