Converting a PDF to PDF/A creates a version of the document compliant with the ISO standard for long-term archiving. The PDF/A format guarantees that the document is self-contained (fonts, colours and metadata embedded) and will remain readable in the future, regardless of the software available.
PDF/A is required by public bodies, digital archives, law firms and organisations that need to preserve documents for years or decades. OnlinePdfEditor produces PDF/A-1b files, the most common subset of the standard, compatible with most document management systems.
Conversion happens in the browser via pdf-lib, without transmitting the file to external servers.
PDF/A is an ISO standard (ISO 19005) for long-term archiving of electronic documents. It ensures the document can be read identically even decades from now, embedding all necessary elements (fonts, colors, metadata) in the file.
PDF/A-1 is the base standard (2005). PDF/A-2 (2011) adds JPEG2000 support and optional layers. PDF/A-3 (2012) allows attaching any file type. The tool generates PDF/A-2b, the most widely used profile.
No. The conversion happens entirely in the browser with pdf-lib. The file never leaves your device.
Yes. The PDF/A format is required by many electronic invoicing and document management systems (DMS) as an archiving standard.
PDF/A does not support encryption. If the PDF is protected, you must first remove the password with /sbloccare-pdf.
Possibly yes, because fonts are embedded and metadata is added. The size increase is generally modest (5-15%).
Free, in the browser, nothing to install. Upload your PDF and go.
