What the Resize Signature Image helps you do
Crop, resize, and compress signature images for official forms. Use it to remove excess whitespace and set a signature image to requested pixel dimensions. A readable signature matters more than forcing an unnecessarily tiny file.
How to use this tool
- Step 1: Choose a clear signature image with good contrast.
- Step 2: Crop close to the written signature without cutting strokes.
- Step 3: Enter the width, height and target size shown by the portal.
- Step 4: Download and reopen the result to check that thin lines remain visible.
Checks before you submit
- Prefer a clean white or transparent-looking background when allowed.
- Do not stretch the signature out of proportion.
- Compare both dimensions and KB size with the official instructions.
