Frequently Asked Questions
Is it safe to merge confidential bank statements or contracts here?
Yes! Unlike traditional online PDF tools that upload your files to remote servers, DIY Toolkit runs pdf-lib completely inside your local Web Browser. Your sensitive files never leave your computer.
Is there a file size limit for merging PDFs?
Since processing uses your computer's RAM rather than cloud limits, you can process large PDF files limited only by your device hardware capacity.
