Merge PDF
Combine PDFs in the order you want. Processed in your browser.
Merge PDF joins multiple PDF files into one document. Drag files in, reorder them, and download a single PDF. Everything runs on your device — we never upload your files.
Frequently Asked Questions
Do my PDFs get uploaded?
No. Merge PDF runs entirely in your browser. Files never leave your device.
How many files can I merge?
Free accounts can merge up to 3 PDFs totalling 25 MB. Pro lifts those limits.
Can I change the order of pages?
Use the arrows next to each file to reorder them before merging. Page order inside each file is preserved.
Why did a file fail?
Password-protected or damaged PDFs cannot be merged. Unlock them first, then try again.
