FAQ
Everything you need to know.
Is my sensitive data secure?
Yes! Unlike most online PDF mergers that force you to upload your confidential documents to their servers, our tool uses WebAssembly to merge the files entirely inside your web browser. Your files never leave your computer.
Is there a file size limit?
Because everything runs locally on your device, there are no artificial file size limits. You are only limited by your device's memory.
Can I merge PDFs on my phone?
Absolutely. Our local browser-based processor works perfectly on iOS and Android devices without needing to download an app.
