Merge PDF Files
Quick answer
To merge PDF files online, add up to 50 PDFs below, drag them into order and click Merge and Download. The tool copies every page, unchanged, into one PDF in your browser, so nothing is uploaded. Password-protected PDFs need their protection removed first.

How to use it
- 1 Click the upload area, or drag your PDF files onto it.
- 2 Drag the files into the order you want.
- 3 Click Merge and Download. The combined file saves as merged-file.pdf.
What to expect
- Every page is copied as it is: text, images, fonts and page sizes don't change.
- Encrypted or password-protected PDFs may fail to merge. Remove the protection in the app that created them, if you're allowed to.
- Very large files are limited by your device's memory, because merging happens in the browser.
Frequently asked questions
Is this PDF merger safe for private documents?
Yes. The PDFs never leave your device; your browser reads and combines them and saves the result to your downloads.
Does merging change the quality of my PDFs?
No. Pages are copied into the new file without re-rendering, so text stays selectable and images keep their resolution.
How do I combine Google Docs into one PDF?
Download each Doc as a PDF and merge them here, or use document tabs and File > Download > PDF with All Tabs.
Can I merge password-protected PDFs?
Usually not. Remove the password in the PDF app first (only if you have the right to), then merge.
Are bookmarks and links kept?
Page content, including links on the page, is copied. Bookmarks (the outline panel) from the original files may not carry over.
