Add at least 2 PDF files to merge.
Merging happens entirely on your device using the open-source pdf-lib engine loaded in your browser. Nothing is sent anywhere. Works on phone and desktop.
Why merge PDFs?
Job applications: combine your CV, cover letter and certificates into one file.
School & office: join scanned pages or reports into a single document.
Less clutter: one file is easier to email, upload and archive than five.
Private by design
Most free PDF mergers upload your files to their servers. This tool does the opposite: the merge runs inside your browser, so sensitive documents — IDs, contracts, payslips — never touch the internet beyond loading this page.
