How long does a conversion take?
Most conversions finish in just a few seconds. Larger or more complex files may take a little longer depending on your connection and the file itself.
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.
