How to use it
- Choose two or more PDFs.
- Use the arrows to set the order.
- Press Merge.
What is kept
Every page is copied with its text, images, fonts and links intact. Bookmarks (the outline sidebar) and fillable form fields from the source files are not carried over; flatten or fill forms before merging if you need their contents.
To merge only some pages of a file, split it first, then merge the parts.
Questions
Is there a limit on files or size?
No fixed limit. It depends on your device’s memory; a few hundred MB total is fine on most laptops.
Is my PDF uploaded?
No. Pages are copied between PDF files with pdf-lib inside your browser. Nothing is sent anywhere.
Does this reduce quality?
No. Pages are copied as they are, so text stays selectable and images keep their original quality.
Can I merge images and PDFs together?
Convert the images with JPG to PDF first, then merge the result with your other PDFs.
