Is there a limit on how many PDFs I can merge?

No. There is no cap on the number of files or their size, and your first merge works the same as your hundredth. Because the work happens in your browser, the practical limit for very large documents is your device's memory rather than a server quota.

Will merging lower the quality of my pages?

No. Pages are copied into the new file unchanged, so text stays sharp and selectable and images are not compressed a second time. The merged file is roughly the size of the originals added together.

Can I merge a PDF that needs a password to open?

Unlock it first with Unlock PDF, using the password you already have, then merge the unlocked copy. Nopload never tries to guess or break passwords.

Can I reorder single pages instead of whole files?

Merge PDF works with whole files. To move, rotate or delete individual pages across several PDFs, use Organise PDF, which shows every page as a thumbnail you can drag into place.

What are the bookmarks for?

With the option on, the merged PDF gets an outline with one entry per original file, named after it. Most PDF readers show the outline in a side panel, so readers can jump straight to the start of each part.

How to use Merge PDF

01Select the PDFs you want to combine, or drop them onto the page. You can add more files later, as many as you like.
02Put the files in order by moving them up or down, or sort them by name. Leave “Add a bookmark for each file” on to get an outline entry per file.
03Press Merge PDFs. The combined document is put together on your device and downloads as a single PDF, ready to share or to pass to another tool.

About Merge PDF

Merge PDF joins two or more PDF files into a single document. Pages keep their size, orientation and quality, because they are copied across as they are rather than redrawn. Links inside each file keep working, and an optional bookmark marks where each original file starts, so a long combined report stays easy to find your way around.

Why your files stay private

Merging happens entirely inside this browser tab. Your PDFs are read from your disk into memory, combined by code running on your own device and handed back as a download. No copy is sent to Nopload or to anyone else, which you can confirm in your browser's network panel while the merge runs.
