Tips for a good result

What this tool does not do
- It does not produce certified PDF/A: that requires validation (ICC, XMP) done by server-side tools such as Ghostscript or VeraPDF.
- It does not change the visual content.
Frequently asked questions
- Does this generate PDF/A?
- No. WebFaz rewrites the structure, but does not declare or validate PDF/A conformance. If an agency requires PDF/A, use a specific validator.
- Does it reduce the size?
- That is not the goal. To reduce it, use Compress PDF.
