Merge PDF
"Combine multiple PDF documents into a single professional-grade file quickly and securely."
01What is Merge PDF?
Our Merge PDF tool is built for security-conscious professionals who need to join multiple documents together without relying on third-party cloud servers. Traditional online PDF mergers require you to upload your files, exposing sensitive tax documents, contracts, or personal records to external servers. This tool changes that by running entirely within your web browser. Using advanced web technologies, it runs a localized PDF parser that merges your files locally in your system's memory. Whether you have two PDFs or twenty, you can combine them instantly and download the final combined document without any data leakage.
02How to use Merge PDF
Drag and drop your PDF files into the secure upload zone, or click to choose them from your files.
Check the preview cards to see each file's size, page count, and order.
Use the up and down arrow buttons on the preview cards to reorder your documents into the correct sequence.
Click the 'Merge PDFs & Download' button to combine the files locally in your browser.
Watch the success animation, and find your newly merged PDF downloaded automatically to your device.
