Frequently Asked Questions
Are my PDF files uploaded to any server?
No. All PDF merging executes 100% locally in your browser RAM using WebAssembly. Your files never leave your computer.
Is there a file size limit?
No server-imposed limit exists. Because processing runs in your device's memory, you can merge documents of any page count.
