Merge PDF
Combining contracts, scans, or chapter drafts into a single document takes seconds with the PDF Hub merger. Add two or more files, drag them into the exact order you want, then click Merge PDF. Each file is read straight from your device and stitched together in your browser tab, so confidential documents never touch a server. There is no file-count limit, no watermark, and no account to create. The result is one clean, sequential PDF that is ready to save, email, or print — usually in under a second, even for multi-megabyte scans.

Frequently asked questions
Is there a limit to how many PDFs I can merge?
No. You can merge as many PDF files as your device can hold in memory. Because merging runs locally in your browser, there are no server-side size caps, and every merge is free and unlimited.
Does merging reduce the quality of my PDF?
No. Pages are copied byte-for-byte into the new document, so vector text, images, and links keep their original quality. Nothing is re-rendered or recompressed during a merge.
