How long does a conversion take?

Can I merge several PDF files into one?
Yes. Open the PDF Merger tool, add two or more PDF files in the order you want, and combine them into a single PDF you can download right away.
Will my formatting be kept?
Our conversion engine works hard to preserve your layout, text, and images as closely as possible. Results can vary with very complex documents, so it is always worth checking the finished file.
