$ cat FAQ.md
Is my data sent to a server?▶
No. The entire merge process happens in your browser using pdf-lib. Your PDF files never leave your device — there is no upload, no server processing, and no data collection.
Is there a limit on the number of files I can merge?▶
There is no hard limit. You can merge as many PDF files as your browser's memory allows. For very large files (hundreds of megabytes), you may experience slower performance.
Can I reorder the pages before merging?▶
You can reorder the PDF files using the up/down arrows before merging. The pages from each file will appear in the merged output in the order you arrange them. Individual page reordering within a file is not supported.
Does this preserve bookmarks, links, and form fields?▶
The merge preserves page content, annotations, and embedded fonts. However, cross-document bookmarks, form fields, and some interactive elements may not carry over due to limitations of client-side PDF processing.
