Merge PDF files
Join multiple PDF files into a single document — drag to reorder, then download. Everything happens in your browser; nothing is uploaded.
What does merging do?
Merging stitches the pages of two or more PDFs into one continuous file, keeping the original page order within each document. It's the fastest way to turn scattered attachments, chapters, or scans into a single deliverable.
Why merge in the browser?
Uploading confidential contracts or medical records to a random website is a real risk. This tool assembles the combined PDF entirely on your device using the pages' own structure, so nothing ever leaves your computer.
Quality & fidelity notes
Pages are copied, not re-rendered, so text stays selectable, fonts stay embedded, and image quality is untouched. The result is byte-for-byte the same content, just in one file.
