How many PDFs can I merge at once?

You can merge as many PDFs as you need in a single operation. Upload them all together and they'll be combined in the order you arrange them.

Can I change the order of pages before merging?

Yes. After uploading, you can drag the files to reorder them before starting the merge. The pages appear in file order.

Will the merged PDF keep the original formatting?

Yes. Merging copies the pages from each PDF as-is — fonts, images, layouts, and page sizes are all preserved.

Can I merge password-protected PDFs?

We attempt to include encrypted PDFs in the merge. If a PDF has a strong access restriction, you may need to remove the password first.

Is there a file size limit?

Each individual PDF can be up to 100MB. For very large files you may need to compress them first.
