All-in-One Signature Resizer for All Indian Government & Competitive Exams
Whether you are filling out an application form for India Post (GDS), IBPS Bank PO/Clerk, SSC (CGL, CHSL, GD, MTS), Railway RRB, PAN Card (NSDL/UTI), NTA NEET/JEE, or UPSC, an incorrect signature file size or dimension is the #1 reason for form rejection. Our Photocopywale Signature Resizer Pro is specifically tuned to rotate sideways signatures, crop unnecessary background space, adjust DPI density (72 to 300 DPI), downsample high-resolution scanner files cleanly, boost pen stroke contrast, and pad the output to hit exact target limits like 20KB - 100KB.
100% Secure & Client-Side: All operations are performed strictly within your browser via HTML5 Canvas. Your signature image is never uploaded to any server or third party.

Frequently Asked Questions (FAQs)
1. What is the signature size requirement for India Post (GDS)?
For India Post GDS applications, the signature must be exactly 300x120 pixels, in JPG format, with a file size strictly between 20 KB and 100 KB, and the DPI must be between 72 and 150. Our exact preset handles all these rules instantly.
2. What is the standard signature size for IBPS banking forms?
For IBPS Bank PO, Clerk, and RRB exams, the signature dimensions must be 140x60 pixels, and the file size must be between 10 KB and 20 KB.
3. How do I fix a vertical or sideways signature?
Use the 'Rotate Left (90°)' or 'Rotate Right (90°)' button in the top action bar. The canvas will immediately reorient the image horizontally without losing any sharpness.
4. Why do resized signatures appear faint or broken?
When shrinking high-resolution images to small dimensions like 140x60 px, thin pen strokes tend to blur. Our tool utilizes progressive bicubic downsampling combined with an Ink Darkness filter to keep pen marks bold and legible.
5. How can I crop out extra background from my signature?
Simply upload your image and click the 'Crop' button in the top menu. A professional crop workspace will open, allowing you to easily cut out unwanted white space in HD quality before resizing.
6. How does this tool achieve an exact file size (e.g., 95 KB)?
Our precision engine compresses the JPEG image dynamically and uses non-destructive COM metadata padding to hit exactly your target KB, ensuring exam portals never reject the file for being under or over the limit.
7. How does the DPI feature work?
DPI (Dots Per Inch) determines print density. For forms asking for 72 to 150 DPI, select the desired value from the DPI dropdown. Our code injects the exact DPI marker directly into the JPG JFIF header without degrading image pixels.
8. What are the signature guidelines for SSC and Railway (RRB) exams?
SSC exams strictly require a 140x60 px signature between 10 KB and 20 KB. Railway RRB requires 140x60 px dimensions as well but allows a slightly more flexible file size of 10 KB to 40 KB.
9. Will this tool remove paper shadows and scanner tint?
Yes! The 'Pure White Background' toggle feature cleans up yellowish or grayish paper tints automatically while preserving dark signature strokes.
10. Is it safe to upload my signature on Photocopywale?
Absolutely. All operations (resizing, cropping, rotating, DPI tagging, and padding) are performed locally inside your browser via HTML5 Canvas. We do not store or upload your sensitive signature images to any cloud servers.
