Why Use PDFHome?
Built to be faster, more private and more reliable than typical online PDF mergers.
100% private by design
Merging happens entirely in your browser using WebAssembly — your PDF files are never uploaded to any server, so there's nothing to leak and nothing to clean up.
No file size games
No forced downgrades, watermarks, or artificial page limits on the free tier. Merge as many PDFs as your device's memory allows.
Preserves quality perfectly
Pages are copied at the vector level, not rasterized — text stays sharp, selectable and searchable, and embedded fonts and images keep their original quality.
Works on any device
PDFHome runs in any modern browser on Windows, macOS, Linux, Chromebook, iPhone, iPad and Android — no app to install.
Instant, no waiting in a queue
Because there's no upload step, merging starts the moment you click the button — no server queue, no waiting for your turn.
Free, no account required
Merge PDF is completely free with no sign-up, no email address, and no hidden subscription upsell.
Frequently Asked Questions
Yes. Merge PDF processes your files entirely on your own device using your browser's built-in capabilities. The files are never transmitted over the internet, so confidential contracts, medical records or financial statements never leave your computer.
There is no hard-coded limit. In practice you're limited only by your device's available memory — most laptops and phones can comfortably merge dozens of typical PDF files in one go.
No. PDFHome copies each page's original content directly, so text remains crisp and selectable, images keep their original resolution, and nothing is re-compressed or rasterized during a merge.
Yes — use the up and down arrows next to each file in the queue to reorder them before merging. The files will appear in the final PDF in exactly that order.
PDFHome will attempt to open password-protected files, but if a PDF is encrypted with a user (open) password, you'll need to unlock it first using our Unlock PDF tool before it can be merged.
No. Merge PDF runs entirely in your web browser — there is nothing to download or install, and it works the same way on Windows, Mac, Linux, Chromebooks, and mobile devices.
