How to Resize Your Signature — Step by Step
- Upload your signature image. Tap the upload area and select a clear photo or scan of your handwritten signature on white paper. JPG, PNG, and WEBP formats are supported.
- Enter the required width and height in pixels. Check the official exam notification for exact dimensions. Common sizes are 140×60 px (IBPS, SSC GD) and 236×79 px (SSC CGL).
- Set your maximum file size. Choose 10KB, 20KB, 50KB, or enter a custom value. The tool will compress the image to stay within this limit.
- Select the output format. JPG (JPEG) is accepted by most portals. PNG is useful if your application specifically requests it or if you need a transparent background.
- Click "Resize Signature". The tool processes your image entirely in your browser using high-quality scaling algorithms and iterative compression.
- Review the preview and file size. Check that your signature is legible and the file size badge shows the correct KB value. If the signature looks blurry, try uploading a sharper original.
- Download the optimized image. Click "Download Signature" to save the resized file. The filename includes the dimensions for easy identification.
- Verify before submission. Open the downloaded file on your computer or phone to confirm it displays correctly before uploading to the exam portal.

Detailed Signature Size Requirements for SSC, RRB, IBPS & UPSC Exams
SSC Signature Size Requirements (CGL, CHSL, GD, MTS, CPO, JE)
The Staff Selection Commission (SSC) conducts multiple recruitment exams every year, and each exam has specific signature dimension requirements. For SSC CGL 2026 (Combined Graduate Level), the prescribed signature size is 236 × 79 pixels with a file size between 10 KB and 20 KB in JPEG/JPG format. At 96 DPI, this translates to approximately 6.0 cm × 2.0 cm. The CGL portal automatically validates these parameters, and any deviation results in an immediate upload rejection.
For other SSC exams such as SSC GD (General Duty), SSC MTS (Multi-Tasking Staff), SSC CPO (Central Police Organisations), and SSC JE (Junior Engineer), the signature requirement is typically 140 × 60 pixels with a 10-20 KB file size. However, candidates must always verify the specific dimensions from the official notification, as requirements can change between recruitment cycles.
Important SSC note: SSC portals explicitly require signatures in running handwriting. Signatures submitted in BLOCK or capital letters will be rejected. Your signature must be in your natural cursive/writing style on plain white paper with black or blue ink. This requirement is strictly enforced across all SSC recruitment portals.
Pro tip: Before resizing your signature for any SSC exam, download the detailed notification PDF and look for the "Scan/Upload of Signature" section. The exact pixel dimensions and KB limits are always mentioned there. Bookmark this page for quick reference, and use our tool to resize your signature to the exact specifications.
IBPS & Banking Signature Size Requirements
The Institute of Banking Personnel Selection (IBPS) conducts recruitment for IBPS PO (Probationary Officers), IBPS Clerk, IBPS RRB (Regional Rural Banks), and IBPS SO (Specialist Officers). All these exams require a signature with standard dimensions of 140 × 60 pixels in JPG/JPEG format with a file size between 10 KB and 20 KB. The signature must be in black or blue ink on a white background.
SBI PO and SBI Clerk (State Bank of India) follow the same signature requirements as IBPS: 140 × 60 pixels, 10-20 KB, JPEG format. RBI Assistant and RBI Grade B officer exams also use similar specifications. For banking applications, ensure your signature strokes are bold and clear — thin or light signatures often become illegible when compressed to 10-20 KB.
Banking tip: Many banking portals require you to upload your signature and photograph in a single session. Have both files ready in the correct dimensions before you start the application. Our Signature Resizer can help you prepare compliant signature files for all major banking exams in under a minute.
RRB (Railway Recruitment Board) Signature Requirements
The Railway Recruitment Board (RRB) conducts exams for various technical and non-technical positions. RRB applications typically require a signature of 140 × 60 pixels in JPG format with a file size between 10 KB and 40 KB. However, candidates should note that RRB NTPC (Non-Technical Popular Categories) recruitments such as CEN-06/2025 and CEN-07/2025 may have slightly different specifications depending on the notification.
RRB ALP (Assistant Loco Pilot), RRB Technician, RRB JE (Junior Engineer), and RRB Group D recruitments all require a clear handwritten signature scan. The signature must be in running handwriting, not in block letters. A common reason for RRB application rejection is uploading a signature that appears stamped or computer-generated. Ensure your signature looks naturally handwritten when viewed at 100% zoom.
UPSC Signature Requirements
The Union Public Service Commission (UPSC) has unique signature requirements that differ from SSC and banking exams. For the UPSC One Time Registration (OTR), candidates need to upload a square signature image with dimensions between 350 and 500 pixels on each side. The file format is JPEG, and the size should be between 10 KB and 100 KB. This is a square format, unlike the rectangular signatures required by other exams.
For the UPSC DAF (Detailed Application Form) stage — which comes after clearing the Civil Services Preliminary exam — candidates must upload 3 separate signatures at different stages of the form. Each signature must meet the dimensions specified in the DAF notification. UPSC also requires a declaration that the signature uploaded is your own handwritten signature. Using our signature resizer, you can quickly prepare all required signature files for each UPSC stage.
Common Signature Rejection Reasons & Solutions
| # | Rejection Reason | Solution |
|---|---|---|
| 1 | File size exceeds limit | Use our tool to compress to exact KB |
| 2 | Wrong dimensions | Enter exact pixel dimensions from notification |
| 3 | Wrong format (PNG instead of JPG) | Select "JPG (Standard)" in format dropdown |
| 4 | Signature is blurred/not legible | Re-photograph with better lighting; use thick pen |
| 5 | Signature uses BLOCK/CAPITAL letters | Re-sign in running/writing style handwriting |
| 6 | Signature has colored background | Ensure white paper background |
| 7 | Signature cut off or incomplete | Leave margin around signature, crop tightly |
| 8 | Signature too small/miniature | Sign larger (cover ~5 cm width) before resizing |
| 9 | Signature contains smudges or marks | Use fresh ink on clean paper |
| 10 | Wrong file name or extension | Save as `signature.jpg` (not .png) |
Expert Tips for a Successful Signature Upload
- Always verify from the official notification. Exam requirements change yearly.
- Keep a digital copy with the exam name in the filename.
- Test your signature on the portal preview before final submission.
- Don't reuse the same file for different exams. SSC CGL needs 236×79; IBPS needs 140×60.
- Make strokes bold and clear. Thin signatures become illegible at 10-20KB compression.
- Apply during non-peak hours. Portals get overloaded on deadline days.
Our free Signature Resizer allows you to resize signatures to 10KB, 20KB, 50KB, and custom dimensions within seconds — all entirely in your browser. Whether you are applying for SSC, RRB, IBPS, SBI, UPSC, NTA, State PSC, or other competitive examinations, you can quickly create a compliant signature image that is ready for online submission.
How can I resize my signature to 20KB?
Upload your signature, enter the required dimensions, set the maximum file size to 20KB, and click Resize. The tool automatically optimizes the image while maintaining clarity.
What is the SSC signature size requirement?
Most SSC applications require a signature image of 140 × 60 pixels with a file size between 10KB and 20KB. Always verify the latest notification before submitting your application.
How do I reduce signature size without losing quality?
Our Signature Resizer uses high-quality image scaling and compression techniques to keep your handwriting sharp while reducing the file size.
Can I resize a signature on my phone?
Yes. The tool is fully mobile-friendly and works on Android, iPhone, tablets, and desktop browsers.
Which image format should I use for online applications?
JPG and JPEG are accepted by most government and banking recruitment portals. PNG is also supported for many online forms.
Is my signature uploaded to a server?
No. All image processing is performed directly in your browser using secure client-side technology. Your signature image is not uploaded to our servers.
What is the RRB signature size requirement?
Most RRB applications require a clear JPG signature that follows the dimensions and file size specified in the latest recruitment notification.
How do I resize my signature to 10KB?
Upload your signature image, enter the required dimensions, set the maximum file size to 10KB, and click Resize. The tool automatically compresses the image quality until the file size is at or under 10KB while preserving as much clarity as possible. For best results at 10KB, use a high-contrast signature with bold strokes.
Can I resize signature to 50KB?
Yes. Simply set the max file size to 50KB in the tool. Our Signature Resizer will optimize your signature to stay within that limit while maximizing image quality. This is useful for portals that accept larger file sizes or for UPSC applications where the limit can go up to 100KB.
What is the signature size in cm?
At standard 96 DPI screen resolution, the most common signature sizes convert as follows: SSC CGL 236 × 79 px ≈ 6.0 cm × 2.0 cm; SSC GD/IBPS 140 × 60 px ≈ 3.7 cm × 1.6 cm. For physical measurement, your handwritten signature on paper should cover approximately 4-5 cm in width before being scanned and resized.
Which format is better — JPG or PNG?
JPG (JPEG) is the preferred format for most government exam applications because it offers significantly smaller file sizes at acceptable image quality — essential for the 10-20 KB limits. PNG is useful if the portal explicitly requests it or if you need to preserve fine details in the signature. Our tool supports both formats.
Why is my signature getting rejected even after resizing?
Common rejection reasons include: using BLOCK/CAPITAL letters instead of running handwriting, uploading a photograph with a colored background, the signature being too faint or blurry after compression, incorrect file extension (.png instead of .jpg), or the file being just slightly above the KB limit. Check our Common Signature Rejection Reasons table above for a complete list of solutions.
Can I resize photo and signature together?
This tool is specifically designed for signature resizing. Photographs have different dimension and resolution requirements and should be resized using a dedicated photo resizer tool. Most exam portals require photographs in square dimensions (e.g., 200×230 px), which are different from signature dimensions.
What if my exam is not listed in the table?
If your exam is not listed in the requirements guide above, refer to the official recruitment notification for that exam. Most portal requirements fall within standard ranges: 140×60 px or 236×79 px dimensions, JPG format, and 10-50 KB file size. You can enter custom dimensions in our tool to match any specification from your notification.
What is the UPSC signature requirement?
For UPSC One Time Registration (OTR), you need a square signature image between 350 and 500 pixels with a file size of 10-100 KB in JPEG format. For the UPSC DAF (Detailed Application Form) stage, you need to upload 3 separate signatures at different steps of the form. Always check the latest UPSC notification for exact specifications as requirements may vary by recruitment.
