How to PDF to PDF/A
- Upload your file — Click "Select PDF files" or drag and drop the document into the upload box. Multiple files are supported where it makes sense.

- Click "PDF to PDF/A" — PDFWix processes the file instantly in your browser. No upload progress bar, no waiting.
- Download the result — Save the new file to your device. The original file is never modified.
Tips for converting PDFs
- PDF/A-2b is the safe default — PDF/A-1 is older and stricter; PDF/A-3 allows attachments. PDF/A-2b is the modern standard for most archival needs.
- Embed all fonts — PDF/A requires every font to be embedded. We do this automatically — just expect a slight file-size bump.
- No encryption allowed — PDF/A explicitly forbids encryption. Don't try to combine with [Protect PDF](/protect-pdf) — they're mutually exclusive.
- Validate after converting — Use a PDF/A validator (e.g. veraPDF) for legal/government submissions. We produce compliant output, but auditors often want proof.
- Once archived, freeze the source — PDF/A is meant for the final, immutable version. Keep your editable source separately.
