How to Resize a Signature to 10KB – 20KB?

SSC Signature Resizer: Resizing a signature for the Staff Selection Commission (SSC) portal requires balancing two things: physical dimensions and file weight. To get your signature between 10KB and 20KB, follow these steps:

1. Use an Online Resizer: Standard image editors often strip quality too much or keep it too high. Our tool is preset to target the 10-20KB range.
2. Adjust the Quality: If your file is above 20 KB, reduce the JPEG quality to 80%. If it’s below 10KB, increase the quality to 95%.
3. Check Dimensions: Ensure the width is 3 times the height (e.g., 140×60 pixels). Incorrect ratios lead to “stretching,” which causes rejection.

Different government exams have slightly different requirements. Use this table as your master guide for 2026 applications:

Exam Authority	Dimensions (Width x Height)	File Size (KB)	Format
SSC (CGL, CHSL, MTS)	6.0 cm x 2.0 cm	10 KB – 20 KB	JPG/JPEG
UPSC (IAS/IFS)	3.5 cm x 1.5 cm	20 KB – 300 KB	JPG/JPEG
IBPS (Banking)	140 x 60 Pixels	10 KB – 20 KB	JPG/JPEG
RRB (Railways)	3.5 cm x 1.5 cm	10 KB – 40 KB	JPG/JPEG
State PSCs	Varies (Usually 3.5×1.5)	10 KB – 50 KB	JPG/JPEG

Why use PhotoKB for signatures?

Using a specialized tool like ours (often referred to as a PhotoKB converter) is better than using basic Paint or Photoshop for several reasons:

• Speed: It takes less than 3 seconds to process.
• Privacy: Since our tool uses JavaScript, your signature is never uploaded to a cloud server. It stays on your phone/PC.
• Compliance: It is hard-coded with the SSC 2026 logic, meaning you don’t have to remember pixel counts or CM-to-pixel conversion formulas.
• Mobile-friendly: You can take a photo of your signature on your phone and resize it immediately without transferring files to a laptop.

Why Was My Signature Rejected?

If you have faced rejection in the past, it is likely due to one of these common mistakes:

1. Faint Ink: Using a light blue or thin-tip pen can cause the signature to disappear under compression.
2. Blurred Image: Shaky hands while taking the photo make the signature unreadable.
3. Capital Letters: Signing in ALL CAPITAL LETTERS is a violation of SSC rules.
4. Shadows/Background: If the background isn’t pure white (e.g., it looks grey or yellowish), the automated scanner fails to recognize the ink.
5. Wrong Size: Uploading a 25KB file when the limit is 20KB.

How to Create a Perfect SSC Signature (Step-by-Step)

Step 1: The Setup

Take a fresh, unruled white A4 sheet. Avoid using notebooks with lines or squares. Use a bold black gel pen for the best results.

Step 2: Sign Naturally

Sign your name in your usual running handwriting. Do not try to make it extra large or extra small. Ensure it fits within a conceptual box of 6cm x 2cm.

Step 3: Capture the Shot

Place the paper on a flat surface near a window for natural light. Hold your phone directly above the signature (parallel to the paper) to avoid perspective distortion.

Step 4: Use the SSC Resizer

Upload your photo to our tool. It will automatically crop the edges and compress the file to sit comfortably between 10KB and 20KB.

Step 5: Verify & Upload

Open the downloaded file. If you can read your name clearly, it is ready for the SSC portal.
