How many PDFs can I merge at once?

You can merge up to 20 PDF files at once, each up to 100 MB. Files are combined in the order they appear in the file list.

Will the merged PDF keep the original formatting?

Yes. Each page is copied exactly as it appears in the original document — fonts, images, links, and layout are all preserved.

Are my files uploaded to a server?

No. All merging happens entirely in your browser using client-side JavaScript. Your files never leave your device.

Can I reorder pages before merging?

The pages are merged in the order you add the files. To reorder, remove and re-add files in the desired sequence. For page-level reordering, use the PDF Split tool to extract specific pages.
