Turn the visible page appearance into non-interactive image content.
PDF.js renders each visible page locally, then a fresh image-based PDF is created. Visible form values and annotations become non-interactive; selectable text, links, and hidden layer states are not retained.
This tool performs full visual flattening: PDF.js renders the currently visible appearance of each page, including visible form widgets and annotations, and rebuilds the document from those page images. The resulting pages no longer contain interactive fields, links, or selectable text.
Only the currently visible optional-content state is rendered; hidden layer states are discarded rather than merged. Processing happens locally in your browser with no file upload.
