About PDFMerger
PDFMerger combines multiple PDFs into one file in your browser using pdf-lib. Your files are not uploaded to our servers for merging. Optional analytics (Plausible) and ads (Google AdSense) may load third-party scripts when enabled by the site owner; see the privacy implications on your deployment.
A one-time payment to download the merged file uses Stripe Checkout (typically after the merge is complete) — no user accounts.
