About Resize a Signature Image
Resize a signature and remove its light background. Set the dimensions, format and file size.
How it works
- Choose a photo or signature image.
- Set dimensions, units, DPI, output format and file-size requirements. Crop or adjust the image if needed.
- Create a preview, verify the measured result and download the image.
Before you download
Use the dimensions and file-size limits required by your application. Presets can be adjusted.
Common questions
Can I remove the paper background?
Yes. Background cleanup works best with dark ink on light paper. Inspect the transparent preview so thin strokes are not lost.
Can I set an exact signature file size?
Yes. Choose an exact target and enable automatic fitting. Review the output dimensions and format because strict size limits can require resizing.
Can I compress a signature to 10 KB, 20 KB or 50 KB?
Yes. Enter the required file-size rule and use automatic fitting. Review the resulting width and height so a smaller file still meets your application’s dimension limits.
How do I create a transparent PNG signature?
Use a clear photo of dark ink on light paper, crop to the signature, adjust paper-background removal and choose PNG with a transparent background. This cleanup targets light paper, not arbitrary photographic backgrounds.
Should I save a signature as JPG or PNG?
Use PNG when you need a transparent signature background. JPG/JPEG uses an opaque background. Check which format your application accepts, then verify the preview and exact output file size.
