Flatten Annotations

Annotation flattening refers to converting editable annotations into non-editable, non-modifiable static images or plain text forms. When the annotations are flattened, all editable elements of the entire document (including comments and forms) will be flattened, so the annotation flattening is also known as document flattening.

This example shows how to flatten annotations:

const savePath = 'file:///storage/emulated/0/Download/flatten.pdf';
// or use Uri on the Android Platform.
const savePath = await ComPDFKit.createUri('flatten_test.pdf', 'compdfkit', 'application/pdf');
const fontSubset = true;
const result = await pdfReaderRef.current?._pdfDocument.flattenAllPages(savePath, fontSubset);
