Handwritten Signature in Blazor SfPdfViewer Component
12 Feb 20261 minute to read
The SfPdfViewer component supports adding handwritten signatures to PDF documents. Handwritten signatures reduce paperwork during review and enable digital verification within the document.
Adding a handwritten signature to the PDF document
Add a handwritten signature using the annotation toolbar.
- Click the Edit Annotation button in the SfPdfViewer toolbar to open the annotation toolbar.
- Select the Handwritten Signature tool to open the signature panel.
- Draw the signature in the signature panel using a mouse or touch input.
- Click Create, then move and place the signature at the desired location on the page.
The added signature becomes part of the PDF annotations and is preserved when saving or exporting the document.
Editing the properties of handwritten signature
Stroke color, thickness, and opacity can be adjusted using the annotation toolbar’s property editors. Select the signature on the page to enable these editors. After placement, the signature can be moved, resized, or removed like other annotations.
