About the Signature Resizer Tool
The MyExamPhoto Signature Resizer is a dedicated utility built to help candidates resize, crop, and compress their handwritten signatures to meet the exact guidelines of Indian competitive exams. Using high-performance local canvas rendering, this tool ensures your file is compressed under strict kilobyte limits (like 20KB or 50KB) without turning blurry or pixelated.
For security, the tool performs all operations 100% locally in your browser. No files are uploaded to any remote server. It is completely free, does not insert watermarks, requires no registrations, and runs on both mobile and desktop screens.
Having a clean, compliant signature is critical. Portals like NTA, UPSC, and state PSCs use automated scrapers to validate upload assets. If the pixels do not match the exact ratio, the form will reject the image instantly.

How to Use this Tool

- Upload File: Drag and drop your image or click to browse. The image will load instantly.
- Adjust Crop: Use the crop handles to frame the signature signature tightly, eliminating unnecessary margins.
- Set Presets: Choose your target exam preset (e.g. SSC, Kerala PSC) to auto-lock the required dimension ratio, or input custom pixels.
- Adjust Compression: Set the Target KB slider to your required limit (typically 20KB).
- Download: Click 'Download Signature' to save the compiled JPG file locally.
Troubleshooting & Helpful Tips
Blurred signature: If the output signature looks blurry, ensure the original photo was captured in high resolution under good lighting. Do not use close-up digital zooms as they add noise.
Incorrect file size: If the size exceeds the target, slide the Compression slider to the left and click download again. The browser will re-render the image with higher JPEG compression.
Form rejection: Ensure you did not write the signature in capitalized block letters, as banking portals (like IBPS) explicitly prohibit block letter signatures.
