What Is PDF Merging?
PDF merging combines two or more PDF documents into a single file while preserving the original formatting, bookmarks, and page layout of each source document. This is useful when you need to consolidate reports, bundle invoices, or assemble chapters into one cohesive document. Our browser-based merger handles the entire process locally on your device, meaning your files are never uploaded to a server and your data stays completely private.

Why Use Our PDF Merger?
Frequently Asked Questions
Can I reorder pages before merging PDFs?
Yes. After uploading your files, you can drag and drop individual pages or entire documents to rearrange them in any order before merging.
Is there a limit on how many PDFs I can merge at once?
There is no hard limit set by the tool. The practical limit depends on your device's available memory, but most users can comfortably merge dozens of documents.
Will the merged PDF keep hyperlinks and bookmarks?
Yes. Internal links, bookmarks, and other interactive elements from the original documents are preserved in the merged output.
Do my PDF files get sent to a server during merging?
No. The entire merge operation happens locally in your browser using JavaScript. Your files never leave your device.
