Merge PDF — combine files in one document
Upload multiple PDFs, drag them into the right order, then merge into a single downloadable file.
Whether you are assembling reports, combining scans, or stitching chapters, you control the sequence first. Drag and drop rows to reorder; the merge uses that order top to bottom.
Merging runs on our servers after you click the button—the combined PDF downloads to your device. Check limits below before uploading very large sets.

What you can do here
Combine PDFs with a clear order you set yourself—no desktop software required.
Add many PDFs at once (within limits), remove mistakes, and merge when you are ready.
Download a single merged PDF with every page in sequence.
Straightforward size caps keep the tool responsive—see the hint under the toolbar.
Nothing merges until you click the button, so you can fix the order first.
How to use it
Click Add PDFs and select your documents. They appear in the merge list.
Drag rows by the handle to put files in the order you want in the final PDF.
Click Merge & download to combine them on the server and save merged.pdf.
What to expect
Password-protected or corrupted PDFs may fail to merge—unlock or repair them first. Very complex files can hit processing limits; try fewer files per request. Always open the downloaded PDF before sharing.

Quick question
Are my PDFs uploaded to merge them?
Yes. Merging runs on our servers so the combined file can be built and sent back to you. Do not upload sensitive documents unless you accept that tradeoff.
