About this tool
Combining PDFs should not require uploading contracts to a stranger's server or installing a hundred-megabyte suite. This merger works entirely in your browser using pdf-lib: drop in two or more PDFs, drag the list into the order you want, press merge, and download a single combined document in seconds. Every page of every file is preserved exactly — vector text, images, and page sizes carry over untouched because pages are copied, not re-rendered. A live list shows each file's name, page count and size so you can catch a wrong file before merging, and one click removes any entry. There are no page limits, no watermarks, no daily caps, and no account. The privacy story is the point: bank statements, legal filings, medical records and unreleased manuscripts are exactly the documents people need to merge and exactly the ones that should never transit a third-party server. Here, the files never leave your machine — you can even disconnect from the internet after the page loads and merge away.

Frequently asked questions
Are my PDFs uploaded?
No. Merging runs entirely in your browser with pdf-lib. Files never leave your device — verifiable in your network inspector.
Is there a page or file limit?
No hard limit. Hundreds of pages merge fine; very large files are bounded only by your device's memory.
Are bookmarks or forms preserved?
Page content is preserved exactly. Interactive form fields and outlines may not survive the merge.
Can I merge password-protected PDFs?
Encrypted PDFs must be unlocked first; the tool will report which file could not be read.
