Digital Signature Converter

Convert your handwritten signature or logo into a transparent digital image.

How to Use
  • Upload Your Signature Image: Click the "Upload your handwritten signature image:" field and select an image file (PNG, JPG, etc.) of your handwritten signature or logo on a background you wish to remove. Your image will appear on the canvas.
  • Set Background Color to Remove: Use the "Background Color to Remove:" picker to select the exact color of the background you want to make transparent. For white paper, this is usually white (`#FFFFFF`). For colored backgrounds, pick the dominant background color.
  • Adjust Color Tolerance: Use the "Color Tolerance:" slider to fine-tune how strictly colors must match the chosen background color to become transparent. Hover over the "Threshold:" text for a tooltip explaining its effect.
  • Choose Signature Color: Use the "Signature Color:" picker to select the desired color for your digital signature or logo. All non-transparent parts of the image will be recolored to this chosen color.
  • Convert the Signature: Click the "Convert Signature" button. The processed digital signature with a transparent background will be displayed on the canvas. A loading spinner will appear briefly during processing.
  • Set Download File Name (Optional): Enter your preferred file name (e.g., `my_signature`) in the "Download File Name (optional):" text box. If left blank, the file will be named `digital_signature.png`.
  • Download Your Digital Signature: Click the "Download Signature" button to save the transparent PNG file to your device.
  • Reset to Original: If you've made changes and want to revert to the original uploaded image and default settings, click the "Reset" button.
