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

There is no hard limit. Most browsers can comfortably merge dozens of PDFs as long as the total size stays below a few hundred megabytes.

Will the merged PDF keep the original page sizes?

Yes. Each source PDF is appended with its original page dimensions preserved. Mixed page sizes (letter, A4, legal) all work correctly.

Are bookmarks and links preserved?

Basic page content is always preserved. Some advanced features like nested bookmarks may not transfer, but links visible on pages are kept.

Can I reorder pages after merging?

Reordering happens before merging in the upload list. For page-level reordering, use a dedicated PDF page organizer.

About Merge PDF

Merge PDF lets you combine two or more PDF files into a single document, perfect for assembling reports, contracts, course materials, or any project where multiple sources need to live as one file. The merger preserves bookmarks, links, and form fields where possible, and runs entirely in your browser using the open-source pdf-lib library. You can drag files into the upload area, reorder them by dragging, remove ones you added by mistake, and download the combined PDF without any watermark or sign-up. The output PDF is a standard, universally readable file that opens in every PDF viewer.

Privacy

Merging happens entirely in your browser. Your PDFs are not uploaded to any server and are not stored anywhere after you leave the page.

Limitations

Total combined size should ideally stay below 500 MB for stable browser performance. Encrypted PDFs must be unlocked before merging.
