Frequently Asked Questions
PDF/A is an ISO-standardized version of PDF specialized for long-term document preservation and archival. Unlike regular PDFs, PDF/A embeds all fonts, color profiles, and resources needed to display the document identically for decades. It's required for legal documents, government records, and corporate archives.
PDF/A-1b: Based on PDF 1.4, most restrictive but widest compatibility (basic conformance). PDF/A-2b: Based on PDF 1.7, supports JPEG 2000 compression, layers, and transparency (recommended for most users). PDF/A-3b: Allows embedded file attachments like invoices, source data, or XML (useful for ZUGFeRD invoicing).
RGB: Recommended for digital archival and screen viewing (smaller file size, device-independent sRGB profile). CMYK: Use for documents intended for professional printing (subtractive color model). Most archives prefer RGB as it's device-independent and future-proof.
No, metadata (title, author, keywords) is optional but highly recommended for archival purposes. It helps with document discovery, cataloging, and compliance. Many organizations require specific metadata for their archival systems.
Yes, completely safe. All processing happens in your browser using WebAssembly. No files are uploaded to servers. Original files are never modified. The conversion creates new PDF/A-compliant files without affecting originals. All fonts and color profiles are embedded for guaranteed preservation.
