Frequently Asked Questions

What is the benefit of PDF/A over standard PDF?

PDF/A is an ISO standardized subset that embeds all fonts, defines device independent color spaces (ICC profiles), and bans external references, guaranteeing readability decades into the future across any reader or operating system.

How does DocScalar secure legal and archival documents during conversion?

Archival processing takes place in encrypted TLS 1.3 transient memory environments with automated zero storage memory purging immediately upon download without server persistence or logging.

What is the maximum file size limit for PDF/A conversion?

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.

Are color spaces standardized during conversion?

Yes. DeviceRGB and DeviceCMYK color definitions are anchored with standard embedded ICC output intent profiles to guarantee deterministic rendering across commercial printing presses and electronic displays.
