What is a PDF to PDF/A Converter?

A PDF to PDF/A converter is a dedicated archiving tool that transforms standard Adobe PDF documents into ISO-standardized PDF/A (Portable Document Format Archive) files. Standard PDFs can contain external fonts, links, video clips, Javascript, and encryption, which might render the file unreadable in future software. PDF/A ensures a file is completely self-contained and ready for archival storage.

Guaranteed Long-Term Readability: By embedding all fonts, styling data, and color spaces directly into the file, a PDF/A document will render exactly the same way decades from now, regardless of changes in operating systems or PDF viewers.

Removal of Dynamic Elements: To ensure archival integrity, our tool automatically strips out interactive widgets, scripts, audio-video links, and password protections, all of which are forbidden under strict PDF/A compliance standards.

Safe and Encrypted Archiving: All files processed by our tool use secure SSL connections. To respect your confidentiality, your uploaded files and generated PDF/A documents are permanently deleted from our servers shortly after processing.

Detailed Validation

Tips for best PDF/A archiving results

Encrypting files is forbidden under PDF/A specifications. If your PDF is locked, unlock it using our Unlock PDF tool before starting the conversion.

Ensure original text fonts are properly embedded. If fonts are missing, the converter might substitute them with standard system fonts, which could alter the layout slightly.

For scanned archives, ensure document images are crisp and readable. Use 300 DPI scans to retain details and layout sharpness in the final PDF/A document.

Dynamic elements like video clips, audio players, or form submit buttons will be removed or flattened during the archiving process to satisfy ISO standard limits.

For professional color-sensitive print documents, verify that CMYK or RGB color profile metadata is included so that colors look correct on future systems.

Standard compliance level (typically PDF/A-2b) ensures that the visual appearance of the file is preserved. Run compliance checkers to verify conformance.
