FAQ
How many PDFs can I merge?
There is no hard limit. You can combine dozens of files as long as the total size stays within your browser's memory. Each file can be up to 100 MB.
Can I reorder the files?
Yes. Use the arrow buttons next to each file to move it up in the list before merging.
Are my files uploaded to a server?
No. Merging happens entirely in your browser using pdf-lib. Your files stay on your device.
Will the merged PDF keep bookmarks and links?
Basic page content is preserved. Some interactive features like bookmarks or form fields may not carry over.
