Open source library and command-line tool for verifying and converting PDF documents to PDF/A-1b format with industry-compliant validation.
The story so far
gopdfrab is a pure-Go library and CLI for PDF/A-1b verification and conversion. It validates PDF documents against the PDF/A-1b standard with 159 checks across 11 groups, passing all tests in the Isartor and veraPDF test suites. The tool can convert non-compliant PDFs to PDF/A-1b format using pre-emptive fixups and a verify-fix loop with raster fallback. It offers both a Go package and a standalone command-line binary, supports encrypted PDFs with RC4 and AES decryption, includes damage recovery for broken documents, and runs as WebAssembly in browsers. The library has zero runtime dependencies and is cross-platform, running anywhere Go runs.
