PDF Merger

Combining several PDFs into one (scanned receipts, a multi-part report, several signed contract pages) usually means finding software that isn't already installed, or fighting with an OS's built-in preview tool that wasn't really built for this. This merges any number of PDFs in the order you choose, with simple drag-to-reorder before you download the result.

What happens to bookmarks, links, and form fields when merging

Merging tools vary in how well they preserve a source PDF's internal structure. Bookmarks and internal links can end up pointing to the wrong page after merging if the tool doesn't remap them, and interactive form fields with identical names across two source files can conflict. If your merged document needs bookmarks or forms to keep working exactly as intended, check the merged result carefully rather than assuming it transferred perfectly. This is one of the more common gaps in simple merge tools generally, not unique to any one implementation.

Frequently asked questions

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

No hard limit on count, though very large combined file sizes will naturally take longer to process in-browser.

Can I reorder the pages after merging, or only before?

Reorder the source files before merging by dragging them into your preferred order. The merge follows that order directly, so get it right before combining rather than after.

Does merging reduce quality or compress the files?

No. Merging concatenates the original PDF content without re-compressing it, so quality is unchanged from the source files. Use the PDF Compressor separately if you also want to reduce file size.
