About this tool
Merge PDF combines two or more PDF files into a single document — handy for putting together invoices, assignments, or scanned documents into one file before sharing. Just add your files, drag to reorder them, and merge. Everything runs in your browser, so your files aren't uploaded anywhere.
How to use it
- Click to upload or drag and drop two or more PDF files.
- Drag the files to reorder them if needed.
- Click Merge to combine them into a single PDF and download it.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
You can merge as many PDF files as you need in one go — there's no artificial cap, though very large files may take a little longer to process in your browser.
Are my PDF files uploaded to a server?
No, the merging happens entirely in your browser using JavaScript, so your files never leave your device.
Can I change the order of pages before merging?
Yes, drag and drop the uploaded files into the order you want before merging — the final PDF follows that order.
