Why Use a PDF Merger?
Managing multiple PDF files can be chaotic. Sending five separate attachments in an email looks unprofessional and is annoying for the recipient. By using a PDF Merger, you can create a single, cohesive document that is easier to share, print, and archive.
This tool is perfect for students submitting assignments, professionals seeking to organize reports, or anyone needing to consolidate scanned documents. It replaces the need for expensive software like Adobe Acrobat for basic merging tasks.
Frequently Asked Questions
Is this tool safe to use?
Absolutely. Unlike other online tools that upload your files to a cloud server, our tool processes everything locally on your device. Your sensitive documents never leave your computer.
Can I merge PDF files offline?
Yes! Because our app runs client-side code, once the page is loaded, you can disconnect from the internet and continue merging files securely.
Is there a limit to the file size?
The only limit is your device's memory. Since we don't upload files, you can merge very large documents that would typically be rejected by server-based converters.
Does this work on Mac and Windows?
Yes, our Merge PDF tool works on any operating system (Windows, Mac, Linux) and any modern browser (Chrome, Firefox, Safari, Edge). It also works perfectly on mobile devices.
Can I merge password-protected PDFs?
You will need to unlock password-protected PDF files before merging them. You can use our Remove PDF Password tool to unlock them first, and then merge them here.
