About Merge PDF
Merging PDFs is one of the most common document jobs: joining scanned pages, combining reports, or putting an application form and its attachments into a single file. This tool joins as many PDFs as you pick, in the order you pick them, and downloads one combined PDF.
Everything happens in your browser, so sensitive documents are never uploaded to a server. There is no account, no watermark and no page limit beyond what your device memory can handle.
How to use it
- Choose two or more PDF files in the order you want them merged.
- Press Merge & Download.
- Your single combined PDF downloads straight to your device.
Frequently asked questions
How many PDFs can I merge at once?
There is no fixed limit, but every file is held in your browser memory, so merging dozens of very large PDFs can slow down a tab. For everyday documents, ten or twenty files work fine.
Can I change the order of the PDFs?
Yes - the merged file follows the order in which you select the files. To reorder, just select them again in the order you want.
Are my PDFs uploaded?
No. Merging runs entirely in your browser. Your files never leave your device.
