Merge PDF
A PDF merger combines several PDF files into a single document, preserving every page's text, vectors, and images, and does it entirely in your browser so the files are never uploaded to a server.

About Merge PDF
Add as many PDFs as you like, drag them into the order you want, and download one merged file. The pages are copied byte-faithfully with pdf-lib — text stays selectable, vectors stay sharp, and nothing is rasterized or re-compressed. Because it all runs in the tab, you can merge signed contracts, invoices, or scans without handing them to a third-party PDF site.

Smallpdf and iLovePDF alternatives that never upload your files

If you'd rather your file never leave your device at all, the strongest alternative is a set of in-browser PDF tools that do the work locally. Here's an honest comparison of when each approach wins.
