One of the leading causes of online application rejections for competitive exams (SSC CGL, CHSL, GD, UPSC IAS/CDS, IBPS PO, and State PSCs) is improper image formatting.
Recruitment servers enforce strict automated image validation scripts:
- If your photograph is 51 KB instead of under 50 KB, the server rejects it.
- If your signature image is 9 KB instead of the required 10 KB – 20 KB window, submission fails.
- If you compress an image carelessly, the signature becomes pixelated and illegible, risking disqualification during document scrutiny.
Here is the complete specification cheat sheet and a step-by-step guide to resizing your photograph and signature to exact dimensions directly in your browser.

How to Resize Photo and Signature Online (Step-by-Step)
- Open the Resizer Tool: Navigate to PDFTools4U Image Resizer & Compressor.
- Upload Your Image: Drag and drop your raw passport photo or a clear scan/photo of your handwritten signature.
- Crop Out Extra Margins: Use the crop box to remove shadows and blank paper margins around your signature.
- Set Exact Target Dimensions & KB:
- For SSC/IBPS Photo: Set dimensions to 200 x 230 px and target file size to 35 KB (safely between 20KB and 50KB).
- For SSC/IBPS Signature: Set dimensions to 140 x 60 px and target file size to 15 KB (safely between 10KB and 20KB).
- Convert & Download: Choose JPG / JPEG format and click Resize & Download. The browser-based engine compresses the file locally without compromising contrast or clarity.
4 Common Mistakes That Cause Image Rejection
- Signing in Capital Letters: Banking portals (IBPS/SBI) and SSC explicitly reject signatures written entirely in block capital letters. Always sign in your natural running handwriting.
- Using Blue Ink Instead of Black: Most exam notifications mandate black ink on plain white paper. Black ink provides high contrast for automated scanning systems.
- Taking Blurry Photos of Old Passport Pictures: Capturing a photo of a physical printed passport picture causes glare and graininess. Take a fresh selfie against a well-lit white wall in natural light.
- Wrong Aspect Ratio (Stretched Faces): Forcing arbitrary pixel dimensions without maintaining the original aspect ratio distorts facial proportions. Crop your image to passport proportions (3.5 : 4.5) first before resizing.
Why In-Browser Processing is Essential for Identity Documents
Photos, signatures, and biometric identity proofs are personal identifiers. Uploading your raw signatures to cloud-based image converters creates unnecessary risk.
