PDF to PDF/A — Convert to Archival Format
Convert standard PDFs to PDF/A for long-term preservation and compliance. Choose a conformance level, and the tool embeds a color profile, sets the output intent, and writes the PDF/A metadata. Everything runs in your browser.
Key Features
Multiple Conformance Levels
Choose PDF/A-1b, PDF/A-2b, or PDF/A-3b depending on the compatibility and features you need.
Embedded Color Profile
An sRGB ICC color profile is embedded and registered as the document output intent, as PDF/A requires.
PDF/A Metadata
The correct PDF/A conformance metadata (part and conformance) is written into the document's XMP information.
Batch Conversion
Convert up to 10 PDFs at once and download them individually or as a single ZIP archive.
100% Private
All processing happens locally in your browser. Your files are never uploaded to any server.
No Install, Free

What Is PDF/A?
PDF/A is an ISO-standardized format for the long-term preservation of electronic documents. Unlike a regular PDF, a PDF/A file guarantees that the document can be reproduced identically decades from now, regardless of the software or system used to open it. It achieves this by embedding all fonts and color profiles, setting a clear output intent, and storing descriptive metadata. PDF/A is widely required by archives, government agencies, courts, and businesses for records that must be kept for years. This tool converts a standard PDF into a PDF/A document by embedding an sRGB color profile, adding the output intent, and writing the PDF/A conformance metadata — all locally in your browser.
How to Convert a PDF to PDF/A
Converting to PDF/A takes just a few steps. Everything runs in your browser.
Upload the PDFs
Drag and drop up to 10 PDF files, or click the upload area to select them.
Choose a conformance level
Select PDF/A-1b, PDF/A-2b, or PDF/A-3b. PDF/A-2b is recommended for most documents.
Convert the files
Click Convert to PDF/A. Each file is processed and the PDF/A metadata and color profile are written.
Download the results
Download each converted file individually, or download all of them as one ZIP archive.
Good to Know
PDF/A forbids encryption and JavaScript, so password-protected PDFs must be unlocked first and cannot be converted as-is. This browser-based conversion embeds an sRGB color profile, sets the output intent, and writes the PDF/A conformance metadata. Font embedding is preserved from the source document; for strict archival validation (for example veraPDF), verify the result with a validation tool and use a desktop converter for documents that must pass certification.
