Merge PDF — why it works this way
Merging is one of the most common everyday PDF tasks — combining scanned pages, invoices, or a contract with its signature page into one file. This tool loads each PDF's raw pages via pdf-lib and reassembles them locally in your browser, so your documents never touch a server.
Is my file uploaded? No. Everything happens locally in your browser using the Canvas/File APIs — your file is never sent anywhere.
FAQs
Are my PDFs uploaded anywhere?+
No. Merging happens entirely in your browser using pdf-lib — your files are never sent to a server.
How many PDFs can I merge?+
No fixed limit — add as many as you like. Very large batches will simply take a little longer since everything processes on your device.
Does merging affect quality?+
No — pages are copied as-is from each source PDF, so text, images, and formatting stay exactly as they were.
Can I change the page order?+
Yes — use the up/down arrows next to each file before merging to set the order.
