Why Signature Size Matters for Government Exam Forms
Government exam portals (SSC, UPSC, IBPS, Railway) have strict upload validators that reject signature images outside the specified pixel dimensions or file size. A signature that is 141×60px instead of 140×60px will fail validation. Getting the exact dimensions right on the first try saves you from re-scanning or re-photographing your signature.
This tool resizes your signature image to any pixel dimension you enter — and keeps the file in your browser with no server upload. After resizing to the correct dimensions, use the Resize Image in KB tool if the portal also requires a specific file size limit (e.g., under 20KB).
Signature Size Requirements by Exam Portal
| Exam / Portal | Signature dimensions | Max file size | Format |
|---|---|---|---|
| SSC CGL / CHSL / MTS | 140×60 px | 10–20 KB | JPEG |
| UPSC Civil Services | 300×100 px | 20 KB | JPEG |
| IBPS PO / Clerk / SO | 800×300 px | 50 KB | JPEG |
| RRB NTPC / Group D | 140×60 px | 20 KB | JPEG |
| SBI PO / Clerk | 800×300 px | 50 KB | JPEG |
| NDA / CDS (UPSC) | 300×100 px | 20 KB | JPEG |
| GATE / JAM (IIT) | 160×100 px | 30 KB | JPEG |
| NEET / JEE (NTA) | 160×100 px | 30 KB | JPEG |
Requirements change per notification cycle — always verify against the official exam advertisement before uploading.
Common Signature Upload Problems
Signature rejected — wrong dimensions
The portal checks exact pixel dimensions. Even 1px over the limit triggers a rejection. Use this tool to set the exact width and height required — disable the aspect ratio lock to enter them independently.
Signature too large in KB
Resizing to smaller pixel dimensions reduces file size significantly. If it is still over the KB limit after resizing, use the Resize Image in KB tool to compress it to exactly 10KB or 20KB.
Signature looks blurry after resize
Blurriness happens when upscaling a small signature image to large dimensions. Always start with the highest-resolution scan or photo of your signature. Downscaling preserves quality; upscaling loses it.
Wrong format — portal needs JPEG
If your signature is saved as PNG, the output after resizing here stays PNG. To convert to JPEG, use the PNG to JPG tool first, then re-upload and resize to the required dimensions.

Frequently Asked Questions
What size should my signature be for SSC CGL?▼
SSC CGL requires the signature image to be 140×60 pixels in JPEG format with a file size under 20KB. Enter 140 as width and 60 as height in this tool, disable the aspect ratio lock, click Resize Image, then download. If the output exceeds 20KB, use the Resize Image in KB tool to reduce it.
What are the UPSC signature dimensions?▼
UPSC Civil Services requires the signature to be 300×100 pixels in JPEG format with a maximum file size of 20KB. Set width to 300 and height to 100 (disable aspect lock), resize, and check the output size. Use Resize Image in KB if the file needs further reduction.
How do I resize a signature for IBPS PO or Clerk?▼
IBPS requires the signature at 800×300 pixels in JPEG format with a file size between 10KB and 50KB. This is wider than most portals — set width 800, height 300 with aspect lock disabled, and resize. The output will typically be well within the 50KB limit at this size.
Can I resize both photo and signature with this tool?▼
Yes. This tool resizes any image including both passport photos and signature images. For photo requirements, check the specific dimensions for your exam (e.g., SSC photo is 100×120px, UPSC photo is 300×400px). Process each image separately.
Does resizing the signature change its quality?▼
Downscaling (making smaller) preserves visual quality well. If you start with a clear, high-resolution scan of your signature, the resized output will remain legible. Avoid upscaling a small or low-resolution image — it will appear blurry.
Is my signature image uploaded to a server?▼
No. All resizing happens entirely in your browser using the Canvas API. Your signature file is never sent to any server — it stays on your device throughout the process.
