The Secure Way to Merge PDFs
Why use a local merger?
Traditional online PDF tools require you to upload your files to their servers. This is a massive security risk for sensitive documents like contracts or financial statements. Our tool processes everything on your own CPU.
Fast and Reliable
Since there are no uploads or downloads to a remote server, the merging process is nearly instantaneous. Your only limit is your computer's memory and processor speed.
Works Everywhere
Whether you're on a Mac, PC, or mobile device, our tool works in any modern web browser. No software installation or browser extensions are required.
Frequently Asked Questions
Is there a file limit?
There is no strict limit on the number of files, but very large PDFs (hundreds of megabytes) may cause your browser tab to slow down depending on your device's RAM.
Does it support password-protected PDFs?
Currently, our tool only supports standard, unencrypted PDF files. Encrypted files must be unlocked before they can be merged.
Will it change the quality?
No. Our tool uses pdf-lib to perform a lossless merge. Your images, text, and vector data will remain exactly as they were in the original files.
