Merge PDF
Need to combine several PDFs into a single document? This tool makes it easy to merge multiple PDF files directly in your browser, without installing additional software. Whether you're bringing together reports, combining scanned documents, or organising paperwork into one convenient file, you can arrange your PDFs in the order you want before merging them.
Simply add your PDF files, drag them into the desired order or use the arrows to rearrange them, then merge everything into a single document. All processing takes place on your own device, with no files uploaded to a server, keeping your documents private and under your control.

Good to know
Nothing is uploaded
Your PDFs are read and combined entirely in your browser — they're never sent to a server.
Most encrypted PDFs still work
A PDF that's encrypted but doesn't ask for a password to open (for example, one with only an owner/edit-restriction password) merges fine — its pages are added as flattened images rather than copied directly, so text on those specific pages won't be selectable afterward. A PDF that actually needs a password to open can't be read in the browser and will show an error instead of a page count.
Pages keep their original order
Merging only changes the order of the files — the pages within each file stay in their original order.
Frequently asked questions
How many PDFs can I merge at once?
There's no fixed limit from the tool itself — it's mainly limited by your browser's available memory, since everything happens locally. A handful of typical-sized PDFs merges without any trouble.
Can I change the page order, not just the file order?
Not on this page — merging only reorders whole files, and each file's own pages stay as they were. If you need to reorder, rotate, or delete individual pages, use the Rotate and Reorder PDF Pages tool, either before or after merging.
Does merging reduce quality or file size?
No. Merging copies each page as-is into the new document without re-rendering or recompressing anything, so there's no quality loss. The combined file size is roughly the sum of the originals.
Is my PDF uploaded anywhere?
No. Everything happens in your browser using a JavaScript PDF library — your files are never sent to a server.
