PDF/A is an ISO-standardized version of PDF specialized for long-term preservation of electronic documents. Unlike regular PDFs, PDF/A files are self-contained with all fonts embedded, metadata standardized, and features that might prevent long-term accessibility removed. This ensures documents remain readable and visually identical for decades, regardless of software changes.
Key differences: 1) Fonts - PDF/A requires all fonts to be embedded; 2) Self-containment - PDF/A files include all resources; 3) Metadata - Standardized XMP metadata; 4) Features - PDF/A restricts features that hinder long-term access (like encryption, JavaScript); 5) Colors - Device-independent color spaces required; 6) Compression - Only lossless compression allowed for text/vector data.
PDF/A-1b: Most compatible, best for basic documents. PDF/A-2b: Enhanced features, supports JPEG2000 and layers. PDF/A-3b: Can embed other files (like XML data). PDF/A-2u: Best for multilingual documents with Unicode support. For most users, PDF/A-2b offers the best balance of compatibility and features.
No, the visual appearance should be identical. PDF/A preserves all visual elements while ensuring long-term accessibility. The conversion process embeds fonts, standardizes colors, and removes non-archival features without changing the visible content. You can preview the result before downloading to verify appearance.
PDF/A files are typically read-only for archival purposes. Forms are flattened, annotations are embedded, and the file is optimized for preservation rather than editing. If you need to edit the content, you should keep the original PDF and create a new PDF/A version after editing. Some PDF software can convert PDF/A back to editable PDF if needed.
Yes, our tool supports PDFs up to 100MB and 500 pages maximum. These limits ensure reliable browser-based processing. For larger documents, consider using desktop software or splitting the PDF into multiple files. Note that PDF/A files may be slightly larger than originals due to font embedding.
Yes, PDF/A is widely accepted by government agencies, courts, and legal systems worldwide. It meets international standards for document preservation (ISO 19005) and is often required for official records, court filings, and archival submissions. Many countries have adopted PDF/A as their standard for long-term document preservation.
PDFs with: 1) Password protection/encryption; 2) Embedded JavaScript; 3) External font dependencies that can't be embedded; 4) Certain types of multimedia content; 5) Advanced transparency effects (in PDF/A-1); 6) LZW compression (in PDF/A-1). Our tool will detect and warn about these issues during conversion.
