What this tool does
This tool prepares a photo or scan of your handwritten signature for online forms. It can trim away the white margins around the signature, make the white background transparent, and scale the result to common form sizes or a size you enter.
The output is a clean PNG (with transparency) or JPG, sized to what exam forms, job applications and other portals typically ask for.
How to use it
- Choose a photo or scan of your signature (a dark pen on white paper works best).
- Keep “Trim white margins” on so the signature fills the image neatly.
- Keep “Transparent background” on for a PNG you can place on any form.
- Pick a common size (140×60, 200×70 or 300×100 px) or enter a custom size in pixels.
- Press “Resize signature”, preview, and download the result.
Supported formats
- Input: JPG / JPEG, PNG, WebP, GIF (first frame), BMP
- Output: PNG (transparent) or JPG
Limitations
- Transparency works by turning near-white pixels invisible — very faint grey pencil marks may also fade. Write with a dark pen on plain white paper for best results.
- The output fits inside the chosen size while preserving the signature's own aspect ratio; it does not force exact width AND height at the same time (that would distort your signature).
- Check the pixel size your form requests and pick the matching preset or custom size.
Frequently asked questions
What size should my signature image be?
It depends on the form. Common requirements in India are around 140×60 or 200×70 pixels for exam and job applications. Check the form's instructions and choose the preset or custom size that matches.
Why does my signature look faded after removing the background?
The tool makes near-white pixels transparent. If your pen strokes are light grey, parts of them can fade too. Use a darker pen, or turn the transparent-background option off and use the JPG output.
Is it safe to upload my signature here?
This tool never uploads anything — your signature is processed in your browser and stays on your device. Nothing is stored or sent anywhere.
