How many PDFs can I merge?
As many as you want, but if you're doing 50+ files it might take a while depending on your computer. For best results, try 10-20 at a time.
Will everything look the same?
Yep! All the formatting, fonts, images, and quality stay exactly the same. The merged PDF will look just like the originals, just stuck together.
Can I reorder them?
Yeah, use the up and down arrows to move files around. They'll merge in whatever order you see in the list.
Is it safe for confidential stuff?
Totally. Everything happens in your browser, so your PDFs never leave your computer. Perfect for sensitive documents.
