Why are remote resources disabled?

Remote resource fetching is disabled to protect your privacy and prevent potential security risks like SSRF. Only content within the HTML file itself is rendered. Processing is entirely local.

Can I use CSS in my HTML file?

Yes, inline styles and embedded CSS are fully supported. External stylesheets referenced via URL are not fetched. All rendering happens on your self-hosted SnapOtter server.

What page sizes are supported?

You can configure the output page size and orientation to match your needs, including standard sizes like A4 and Letter. Everything processes locally on your own infrastructure.
