Official Photo & Signature Guidelines
Compare what your form demands with what this tool produces by default:
| Parameter | This tool (default preset) | Official requirement |
|---|---|---|
| Dimensions | 140 × 60 px | Exact pixel dimensions per notification — commonly 140 × 60 px |
| File size | Target 15 KB slider (adjustable) | Must stay inside the notification's KB window — most forms prefer 20–50 KB |
| Format | JPG / JPEG | JPG / JPEG only |
| Name & Date stamp | OFF — toggle anytime | Not required for this document type |
- Sign in black or blue ink on plain white paper with a thick, dark pen.
- Scan or photograph the signature and crop only the signature area — no paper edges.
- Most exam forms require 140 × 60 pixels (or a similar aspect ratio) between 10 KB and 20 KB in JPG format.
- The signature must not be in capital letters — write it exactly the way you normally sign.
- Do not sign with a pencil, park the pen above/below the ruled line, or fold the paper.
- The signature must match the one you produce during document verification.

Frequently Asked Questions
Why do exam forms reject signatures above 20 KB?
Application portals impose strict file-size limits to keep their servers fast and enforce standard dimensions. A signature over the limit fails the upload check instantly, so compressing to 10–20 KB before uploading saves you from failed attempts.
My signature becomes blurry when I compress it to 10–20 KB. How do I fix it?
Blur usually happens when the tool just lowers JPEG quality. This tool instead starts from correct pixel dimensions and finds the highest possible JPEG quality that still fits under your target, then upscales slightly if needed — so strokes stay as dark and sharp as possible.
Which pixel size should I use for my signature?
The most common exam/Government spec is 140 × 60 pixels with a 10–20 KB file size. Always check your specific notification — some boards, like IBPS, ask for different dimensions — and use the Custom Dimensions field here for anything else.
Can I compress a photo of my signature taken with my phone?
Yes. Photograph your signature on white paper in good light, then upload it here. For best results, crop tightly around the signature before compressing and make sure the background is as white as possible.
Tip: if your form also requires a photo with name & date, use the SSC Photo Maker.
