Tips
- For government and exam forms, 300x100 or 400x150 are the most commonly asked signature sizes.
- Scan or photograph your signature on plain white paper, then crop it before uploading for the cleanest result.
- Use PNG format when you need a transparent background for documents; use JPG for a smaller file size.
- Resizing down always looks sharp; avoid resizing a tiny image up too far or it will look blurry.
