Frequently Asked Questions
Is this a real PDF/A converter?expand_more
No. Producing valid PDF/A requires bundling an ICC color profile and writing OutputIntent and XMP metadata, which we can't do reliably from the browser. This tool sanitizes a PDF for long-term storage by flattening annotations, subsetting fonts, and removing JavaScript. Useful but not strict PDF/A. For verified PDF/A output use a server-side tool like veraPDF or Acrobat.
What does the tool actually do?expand_more
It bakes annotations into the page content, subsets the embedded fonts so the file is self-contained, and removes JavaScript so the document can't execute code. The result is smaller and more portable but still a regular PDF.
Why not produce real PDF/A?expand_more
PDF/A requires an embedded ICC color profile, an OutputIntent dictionary, and XMP metadata declaring the conformance level. Producing all of that locally in a browser without bundling a color profile is non-trivial. We chose honest sanitization over fake compliance.
Will the visual appearance change?expand_more
The document should look identical. The changes are all under the hood to keep the file self-contained.
