About this tool
This free online PDF merger combines several PDF files into one document — right in your browser, with no upload and no watermark. Add as many PDFs as you like, drag them into the order you want with the up and down arrows, and download a single merged file. Because the merge happens on your device, your documents stay completely private.
How to use
- Choose or drag in two or more PDF files.
- Reorder them with the up and down arrows until the sequence is right.
- Click Merge to combine them into one PDF.
- Download the merged file.
Why browser-based
Combining PDFs on-device means no upload wait and no server storing your files — ideal for contracts, invoices, scanned documents, and anything confidential. Pages are copied without re-compression, so the merged PDF keeps the original text and image quality.
Other PDF tasks
Merging is one step of organizing a document. You can also split a file into parts, extract specific pages, rotate a sideways scan, or reduce the file size to fit an email limit — all in your browser. Our guide to merging, splitting, and organizing PDFs walks through the whole workflow.
Frequently asked questions
Is this PDF merger free?
Yes — it's a completely free online tool to combine PDF files, with no sign-up, no watermark, and no limits on how many PDFs you merge.
Are my PDF files uploaded to a server?
No. This is a no-upload PDF merger — your files are combined entirely in your browser, so they never leave your device. It's safe for contracts, statements, and other private documents.
How do I change the order of the PDFs?
Use the up and down arrows next to each file to reorder them. The PDFs are merged from top to bottom in exactly the order shown.
Is there a limit on file size or number of files?
There's no fixed limit. Because everything runs locally, very large or numerous files depend on your device's memory, but typical documents merge quickly.
Does merging reduce the quality of my PDFs?
No. Pages are copied as-is into the combined file, so text stays selectable and images keep their original resolution.
Can it merge password-protected PDFs?
It can often open and merge PDFs that only have basic restrictions, but files locked with an open password may not load. Remove the password first if a file fails to load.
Does it work on mobile?
Yes. The tool is fully responsive and runs locally, so you can combine PDFs on a phone or tablet without installing an app.
