How to Scan and Resize Your Signature Using a Mobile Phone
You don't need a bulky desktop scanner to get a perfect signature. Follow these steps using your smartphone:
- Sign on White Paper: Use a thick black or dark blue pen. Ensure the paper has no lines (unruled).
- Scan or Photo: Open your phone camera, clean the lens, focus, and take a photo from directly above.
- Select Exam Presets: Click on "SSC" or "IBPS" to set exact dimensions.
- Enable Auto Clean: Check the "Auto Clean Background" option. This will turn the grey/yellowish paper background into pure white, making the ink pop.
- Download: The tool will auto-compress it below 20KB. Click download and upload it directly to your form!
Common Reasons for Signature Rejection
Thousands of applications are rejected every year due to invalid signature uploads. Avoid these common mistakes:
- Dark or Shadowy Backgrounds: Taking photos in a dark room makes the background grey. Always use the Auto Clean feature.
- Capital Letters: Signatures done entirely in block capital letters are strictly rejected by SSC and IBPS. Use running handwriting.
- Wrong Aspect Ratio: Forcing a square signature into a rectangular 140x60px box will stretch and squash it. Crop your signature closely around the ink before resizing.
- Blurry Images: Compressing an image too much (e.g., trying to force it under 2KB) ruins the quality.
Frequently Asked Questions
How to resize a signature for the SSC Form?
Just select the "SSC" preset from the dropdown above. It automatically sets the required dimensions (140x60 pixels) and restricts the output size to between 10KB and 20KB as per the official SSC guidelines.
How can I reduce my signature file size below 20KB without losing clarity?
Our tool uses an advanced compression algorithm specifically designed for document images. By keeping the target format as JPEG and checking the "Auto Clean Background" option, your signature stays sharp while dropping well below 20KB.
What is the signature requirement for UPSC Forms?
UPSC requires your signature to be at least 350x350 pixels (or a proportionate rectangle) with a file size ranging from 20KB to 300KB. You can use our UPSC preset to meet these guidelines easily.
Can I resize my signature in Centimeters (CM) instead of Pixels?
Yes! In the Custom Mode settings, simply change the "Target Format & Unit" dropdown from Pixels (px) to Centimeters (cm). For example, UP Police requires 3.5cm x 1.5cm.
Is it safe to upload my signature here?
Absolutely. SignatureResizerr processes all images locally inside your browser. We never upload, store, or see your signatures or personal data.
