How to use Merge PDF

Drop two or more PDFs. Drag to reorder. Merge writes a new file that contains every page in sequence. Bookmarks from the originals are not copied, which keeps the result simple and widely compatible.

Combine contracts, scans, and statements into a single PDF. Reorder files before merging. Everything happens locally with pdf-lib.

Questions

Does merge change quality?

Pages are copied, not re-rasterized, so vector text stays sharp.

Can I merge encrypted PDFs?

Only unlocked files. Remove security first.

Is there a cap?

Browser memory is the limit. Hundreds of light pages are fine; huge scanned books may need splitting.
