Frequently Asked Questions

Are external CSS styles and Google Fonts rendered?

Yes. DocScalar utilizes a standards compliant headless rendering engine that accurately interprets CSS Paged Media, flexbox, grid, SVG graphics, and web fonts with full fidelity.

Are my HTML source code, proprietary templates, and invoice markup kept private?

Yes. HTML files and pasted markup are rendered in ephemeral memory sandboxes via TLS 1.3 and wiped instantly upon export with zero permanent storage, logging, or caching.

What is the file size limit for converting HTML to PDF?

DocScalar supports files up to 10 MB in instant guest mode with zero registration required, 15 MB for registered free accounts, and up to 1 GB for Pro tier users. All processing executes in isolated memory buffers with zero data retention.
