How it works
Select your pen color and thickness
Choose official Black ink for Indian government forms or legal documents, or Blue ink for formal contracts. Adjust pen thickness between fine, medium, or bold.
Draw your signature on the canvas
Use your finger or stylus on mobile/tablet, or click and drag with your mouse/trackpad. Use the Undo button if you need to fix a stroke.
Download in your preferred format
Choose 'Download Transparent PNG' for inserting into digital contracts and Word docs, or download the compact JPG and verify its dimensions and file-size range against the active portal notice.
Frequently asked questions
Can I use this signature for official Indian exam forms?
You can create a signature image here, but recruitment portals can require different dimensions, formats, file-size ranges, or a handwritten signature. Use the portal-specific Signature Resizer preset and compare the final file with the active official notice before submitting.
How do I insert the transparent PNG into Microsoft Word or Google Docs?
Download the 'Transparent PNG' file. In Microsoft Word or Google Docs, go to Insert > Image, select your downloaded PNG file, and set the text wrapping to 'In Front of Text' to freely position it above your signature line without blocking text.
Does this tool upload or save my handwritten signature on any server?
The drawing and image generation run in your browser, and the signature data is not uploaded by this tool. Normal page assets may still be requested while the page loads.
How does the stroke smoothing work?
Instead of connecting discrete mouse points with rigid straight lines, our drawing engine calculates quadratic Bézier curves between midpoints of your pointer movement, delivering natural pen-on-paper physics.
The Modern Way to Create a Clean Digital Signature
Traditionally, preparing a digital signature meant finding a clean sheet of white paper, signing with a pen, taking a smartphone photo under imperfect room lighting, transferring the image to a computer, and trying to edit out the grey shadows.
Our Draw Signature Online tool eliminates that entire friction point. By signing directly on your screen, you eliminate shadows, paper texture, uneven lighting, and camera tilt. The result is a transparent graphic or compact white-background JPG that should still be checked against the destination portal's active rules.
Transparent PNG vs. Compact JPG: Which Should You Use?
1. Transparent PNG (For Digital Documents & Contracts)
If you are signing a lease agreement, employment offer letter, invoice, or NDA in Microsoft Word, Google Docs, or a PDF reader, choose Transparent PNG. The alpha channel ensures that only the ink strokes appear on the document, without an unsightly white box covering underlying text or dotted signature lines.
2. Compact JPG (For Forms and Portal Preparation)
Recruitment portals may require JPG/JPEG files, a solid white background, exact dimensions, and a particular file-size range. The Compact JPG export provides a common starting image, but it is not a universal exam preset. Use the Signature Resizer hub and verify the current notice before uploading.
