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.
An optional Download instantly – $2.99 upgrade uses Stripe Checkout for a one-time payment (for example after merge when a delay applies, or when the site requires payment to download) — still no user accounts.
