Frequently asked questions

Are formula results kept in an old .xls?

The values shown in the table (the calculated results) go into the PDF as they are. Since a PDF is a document, the formulas themselves are not kept — only the results.

Is there a file size limit?

No. Because nothing is uploaded to a server there is no upload cap; the only limit is your device memory.

Why is the first run slow?

The office engine is downloaded once the first time. After that it starts right away — you are downloading the engine, not sending your document.

Does my file go to a server?

No. A real office engine runs inside your browser to make the PDF, so contracts and HR files stay on your device.
