FAQ
- Is my data uploaded to a server?
- No. All merging happens entirely in your browser using pdf-lib. Your PDF files never leave your device.
- How many PDF files can I merge at once?
- There is no hard limit imposed by this tool. However, very large files may be limited by the available memory in your browser tab.
- Does the merge preserve bookmarks and form fields?
- Pages are copied faithfully including their visual content. Interactive elements such as form fields and annotations are preserved as part of the page copy operation performed by pdf-lib.
