How to merge PDF files

Why merge PDFs in a browser?

Most free PDF mergers are desktop apps with installers, or websites that upload your files to a server. Browser-based merging using pdf-lib keeps everything local: no upload queue, no file retention policy to trust, no hourly limits. You can merge 2 files or 20 — the only constraint is your device's RAM.
