Merge PDF Files
Frequently Asked Questions
How do I merge multiple PDF files?
Upload two or more PDF files. Drag and drop the thumbnails to set the correct order, then click the 'Merge' button to download the combined document.
Is there a limit to the file size for merging?
Since it happens in your browser, it depends on your RAM. Most users can easily merge files up to a combined 200MB without issues.
Can I merge only specific pages from each PDF?
To do this more precisely, use our 'Split' tool first to extract the pages you need, and then use the 'Merge' tool to combine them.
Will merging lose the hyperlinks in my PDF?
Our merging process preserves interactive elements like hyperlinks, bookmarks, and internal document links in almost all cases.
Do the merged PDFs have a watermark?
No. The resulting merged file is clean and free from any third-party branding or watermarks.
Can I merge PDF files that have different page sizes?
Yes. You can merge an A4 document with a Letter-sized one. The final PDF will simply contain pages of varying dimensions as per the source files.
How long does it take to merge 10 files?
Merging is very fast. It typically takes less than 3 seconds for 10 average-sized PDF documents.
Can I merge encrypted (password protected) PDFs?
You must remove the protection from the source files before you can merge them. Our tool cannot 'look inside' protected files.
What is the best browser for merging large PDFs?
Chrome, Edge, or Brave (Chromium-based browsers) generally have the best memory management for local PDF processing.
Is the merged file the same quality as the originals?
Yes. Merging is a structural operation; we don't re-compress or degrade the quality of the content during the merge.
