Step 2: Access Background Tools:

Click the Edit dropdown menu at the top of the interface and select Smart Background Removal.

Step 3: Auto-Remove the Background

In the right-side panel, under "Auto Remove Background", choose the Products preset to automatically detect and remove the background from your signature image.

Step 4: Refine the Selection Manually

• Click Brush Manually to switch between "Paint" and "Erase" modes, adjusting the brush size to refine the edges of your signature.

Step 5: Customization

Under "Change Background", select the Solid tab and pick a color to ensure your signature blends cleanly with document backgrounds.

Click to Add Image,and upload your target document. Adjust the position and size of your transparent signature to fit the sign field.

Extra Tips

Manual Refinement: If the AI misses small details in a complex signature, use the Brush Manually or Smart Select tools to fine-tune the edges.

Format Compatibility: The tool supports standard web formats including .jpg, .jpeg, and .png files under 10 MB for optimal processing speed.
