Is the PDF Viewer free?
Yes — completely free with no daily limit and no account. ZapMorph’s viewers and developer tools are unmetered.

No. The file is opened by your browser and displayed on this page. It is never uploaded, stored or logged — close the tab and it’s gone.
Does it work on my phone?
