Frequently Asked Questions
What is the maximum number of files I can merge?
There's no strict limit, but performance depends on your device and total file size. For best results, keep total pages under 500.
Can I change the order of files?
Yes! The files are merged in the order they appear in the list. Currently, you can remove and re-add files to change order. Future updates will include drag-and-drop reordering.
Is my data safe?
Absolutely. All merging happens in your browser using JavaScript. No files are uploaded to any server, so your documents remain private.
Does merging affect PDF quality?
No, the original quality of each page is preserved. We use pdf-lib to copy pages exactly as they are.
