Frequently Asked Questions
Are my documents secure when merging?
Absolutely. BrowserKits processes everything locally in your browser using WebAssembly technology. Your PDFs are never uploaded to any server, making this the most secure option for merging confidential documents like contracts, financial reports, or legal files.
Is there a limit on how many PDFs I can merge?
Since processing happens in your browser, there are no server-imposed limits. You can merge as many PDFs as your device can handle. Very large collections may take longer depending on your device's performance.
Will merging affect the quality of my PDFs?
No, the quality remains identical. We combine PDFs without re-compressing or modifying the content. All text, images, formatting, and even interactive elements stay exactly as they were in the original files.
