Drop your PDF file into our secure client-side sandbox. The engine immediately reads the structural layout into the browser's memory without uploading it to any external server. Your sensitive legal and financial reports stay 100% local.
The compiler scans every character and graphic to ensure all fonts and exact ICC color profiles are forcibly embedded inside the file. This guarantees that 50 years from now, the document will look exactly as it does today.
We strip out all non-compliant elements such as encryption, audio, and hidden 3D objects that violate archiving standards. Standard XML-based metadata (XMP) is injected to establish the document's ISO conformance level.
Once compiled, the fully compliant PDF/A file is delivered instantly. Pro users also receive an ISO Validation Report certifying that the document meets strict archival requirements for government or judicial submissions.
A normal PDF may rely on external fonts or link to external content that could break over time. PDF/A is an ISO-standardized version that embeds ALL necessary information (fonts, color profiles) strictly inside the file, ensuring it can be opened and read perfectly even decades from now.
Courts and government archives use the PDF/A-1b standard to ensure long-term reproducibility. Our free tier strictly complies with this standard by normalizing color profiles and locking the visual appearance of your contract or filing.
PDF/A-3b allows for the embedding of entirely different file formats (like an Excel sheet or XML data) inside the PDF. This is widely used in European e-invoicing (ZUGFeRD) where machine-readable XML data is hidden inside the visual invoice. This is available in the PRO tier.
Absolutely not. FixAPDF operates entirely on your device's browser. We do not upload your PDFs to process the archiving, making this tool ideal for strictly confidential documents and NDAs.
