Learn about this tool
The tool to convert PDF to PDF/A creates PDF/A-1, PDF/A-2b, or PDF/A-3b files from a PDF file up to 256 MB. You can enable strict compliance mode if the process requires tighter controls. PDF/A is designed to preserve electronic documents, but successful conversion does not mean the record meets all organizational archiving regulations.
Some PDF files with fonts, colors, encryption, interactive content, or structures may be difficult to convert to the chosen PDF/A profile. Strict mode may reject files that do not meet requirements instead of producing an approximate result. After conversion, use an independent PDF/A validator suitable for the target profile and compare the result with your archiving policy. Legal or business requirements may go beyond the format specifications.

Frequently asked questions
Choose according to the recipient's regulations or storage policy, rather than just selecting the newer version. PDF/A-1 has stricter technical limitations. PDF/A-2b is based on newer PDF capabilities, while PDF/A-3b allows attachments within the standard. If the requirements are unclear, ask the storage unit and verify the types of documents they accept.
No. This is not a certification. In strict mode, the tool will reject the file if it cannot meet the set conversion conditions, so the task may fail. Even if the file is generated, you still need to use an independent PDF/A validator and check the business, legal, or metadata rules of the archive.
The source file may contain non-embedded fonts, incompatible color spaces, encoding, JavaScript, multimedia content, attachments, or structures that cannot be corrected according to the selected profile. These issues are more likely to cause the file to be rejected when using strict mode. Clean the source file if necessary, choose the appropriate profile, and validate again after each conversion.
