PDF to
PDF/A.
Create a PDF/A archive copy when a document needs a longer-term preservation format instead of an everyday PDF.
Convert a regular PDF into an archive-oriented PDF/A copy.
It is useful for records, document retention, and archiving workflows where a preservation-focused version is preferred.
PDF/A-1a, 2a, 2u, 3a, and 3u are processed as best-effort server conversions. Exact compliance depends on the source PDF structure, fonts, and metadata.

When PDF/A is the smarter destination
This tool is useful when a document needs an archive-focused copy rather than an everyday working PDF. PDF/A is often chosen for longer-term storage and records handling.
The profile choice lets you decide which archive target fits the job best.
How to convert PDF to PDF/A
- Upload the PDF file you want to convert.
- Choose the PDF/A profile that best fits your archive needs.
- Start the conversion and let the process finish.
- Download the PDF/A result when it is ready.
PDF/A is designed for preservation, not ordinary compression
PDF/A profiles restrict features that may prevent reliable future rendering. They typically require embedded fonts, defined color information, and self-contained resources while prohibiting certain external or dynamic behavior. Converting to PDF/A does not guarantee that a document is historically important, accurate, or stored safely. It creates a file aimed at a preservation standard that must still be managed within an archive process.
Choose the profile required by the receiving institution rather than selecting the newest or strictest option by instinct. Different PDF/A parts and conformance levels support different features, and organizational policies may mandate one. If no requirement exists, ask the archive or records team. A valid file under the wrong profile can still be rejected by a repository.
Interactive forms, encryption, embedded media, JavaScript, and some transparency or attachment features may be flattened, removed, or disallowed. Digital signatures require special handling. The visible pages may survive while functionality changes. Keep the source PDF and any native authoring files so preservation decisions can be revisited when policy or technology evolves.
Validation is essential after archival conversion
Open the PDF/A result and inspect fonts, colors, transparency, annotations, and non-Latin characters. Compare page count and file size with the source. Visual review alone cannot confirm conformance, so formal archives should run an independent PDF/A validator and preserve its report. A metadata flag that claims compliance is not the same as a file that satisfies every rule.
Add or verify descriptive metadata through the archive workflow: title, creator, dates, language, rights, record identifier, and provenance. Use stable filenames and store checksums so later corruption or replacement can be detected. Redundant storage, backups, access control, and format monitoring matter as much as the initial conversion. PDF/A solves only the file-format portion of long-term preservation.
Do not discard originals after one successful validation. Some source features may have been intentionally omitted to meet conformance, and future archivists may need them. Record the tool and profile used, conversion date, validation outcome, and relationship to the source. A responsible archival package tells future readers not only what the pages look like but also how this preservation copy was produced.
