PDF only · two or more
How to use it
- Drop two or more PDFs onto the berth, or click to pick them.
- Put them in the order you want with the up and down controls.
- Merge. The combined file saves itself, and can go straight into another tool.
About this tool
- Original page visuals are preserved in the merged result.
- This tool merges complete files — it does not edit page content.
- Password-protected PDFs may need to be unlocked first.
- Very large merges can be slower on low-memory devices.
Common questions
Does Merge PDF send my files anywhere?
No. Merging runs locally in your browser. Your PDF files stay on your device.
Can I change the order before merging?
Yes. Each file has up and down controls in the list. Set the order first, then merge.
Will the merged PDF look the same as the originals?
Page visuals are typically preserved — pages are copied into a new PDF. File size may change slightly based on document structure.
Can I merge password-protected PDFs?
Usually not. Encrypted PDFs may fail to merge unless you unlock them first using the Unlock PDF tool.
How many files can I merge?
There is no hard limit in the interface, but very large batches may be slow or run out of memory on older devices.
