Getting rejected on the SSC portal for a photo upload error is one of the most avoidable failures in any exam application. The requirements are specific, consistent across most SSC exams, and published clearly in each notification. This guide covers the exact specifications for every major SSC exam, common rejection reasons, and a step-by-step compression process.
Always verify against the official notification at ssc.gov.in before submitting — requirements can change each cycle.
SSC Photo and Signature Requirements — Exam by Exam
| Exam | Photo Size | Signature Size | Dimensions | Format |
|---|---|---|---|---|
| SSC CGL | 20–50KB | 10–20KB | ~200×230 px (passport) | JPG/JPEG |
| SSC CHSL | 20–50KB | 10–20KB | ~200×230 px | JPG/JPEG |
| SSC MTS | 20–50KB | 10–20KB | Passport size | JPG/JPEG |
| SSC GD Constable | 10–20KB | 10–20KB | Passport size | JPG/JPEG |
| SSC CPO | 20–50KB | 10–20KB | Passport size | JPG/JPEG |
| SSC JE | 20–50KB | 10–20KB | Passport size | JPG/JPEG |
| SSC Steno | 20–50KB | 10–20KB | Passport size | JPG/JPEG |
Most SSC exams share the same 20–50KB photo range and 10–20KB signature range. SSC GD Constable is the exception — it requires a tighter 10–20KB photo limit.
What the Photo Must Look Like
Beyond file size, SSC photos are reviewed manually during Document Verification (DV). A photo that passes the portal upload check can still be rejected weeks later by a human reviewer. Common reasons:
- Coloured or dark background. SSC requires a plain white or very light background. Studio photos on grey gradients or blue backdrops are frequently flagged. A plain white wall works fine.
- Sunglasses, cap, or face partially covered. The full face must be unobstructed. Even a slight angle where one eye is in shadow can cause rejection at DV.
- Glasses. SSC notifications from 2023–24 onwards have progressively restricted photos with spectacles. Check the specific notification for your exam cycle.
- Photo taken more than 6 months ago. SSC requires a recent photograph. Old passport photos — even if they look the same — are rejected at in-person verification.
- Low resolution or pixelated face. Compressing a 200×200 pixel selfie to 20KB produces an unreadable face. Use a high-resolution original and compress down — never start from an already-small image.
- Printed and re-photographed. Taking a photo of a printed photo with your phone creates a low-quality, often moiré-patterned image. Always use the original digital file.
How to Compress Your Photo for SSC
For all SSC exams except GD Constable, target 48–50KB — the maximum allowed. A 48KB face photo is sharper than a 20KB one, and the difference is visible to anyone reviewing your application. Only target 20KB if the portal specifically rejects files above that size.
- Use the original photo from your phone's camera roll or a flatbed scan — not a WhatsApp forward, not a screenshot, not a phone photo of a printout.
- Open the Compress to 50KB tool on PhotoSizeTool. For SSC GD Constable, use the Compress to 20KB tool and target 18–19KB.
- Upload your photo. Wait for the preview to load.
- Check the preview: Are both eyes clearly visible? Is the background light and uniform? Is there any visible blurring around the face or hair?
- If the preview looks blurry, your source image is too large in pixel dimensions for the KB target. Use the 200×230 px resizer to crop and resize first, then compress.
- Download the file. Right-click → Properties (Windows) or Get Info (Mac) to verify the file size is between 20KB and 50KB before uploading.
SSC Signature Requirements
SSC requires a separate signature upload alongside the photo. The rules are strict and consistently enforced:
- File size: 10–20KB in JPG format
- Sign on plain white paper with a black or dark blue ballpoint pen — not a gel pen, not a felt tip
- No ruled lines, no coloured paper, no graph paper — the portal detects background patterns and will reject them
- Use your full signature, not initials or a printed name
- Photograph or scan with even lighting — no shadows across the signature
The single most common signature rejection: signing on lined notebook paper. The horizontal lines appear clearly in the JPG and the portal rejects it. Use a blank A4 sheet, sign in the centre, and photograph it against a flat surface in daylight.
To compress your signature to 10–20KB, use the Signature Resizer tool — it is preset for SSC and IBPS signature dimensions.
Common SSC Portal Error Messages and Fixes
The SSC OTRP (One Time Registration Portal) shows specific error messages when an upload fails. Here is what each means and how to fix it:
- "File size exceeds maximum limit" — Your photo is above 50KB (or above 20KB for GD Constable). Re-compress targeting 48KB using the 50KB compressor.
- "File size is below minimum limit" — Your photo is below 20KB (or below 10KB for GD). This happens when you start from an already-small source image. Use a higher-resolution original from your camera.
- "Invalid file format" — You uploaded a PNG, HEIC, or WebP file. Convert to JPG first — use the HEIC to JPG converter if you are on iPhone, then compress.
- "Image dimensions do not match" — Some SSC registration steps require exactly 200×230 pixels. Use the 200×230 px resizer, download, then compress.
- "Please upload a valid photograph" — Usually triggered by a corrupted file or an unsupported PNG with transparency. Re-export the photo as a plain JPG with no transparency layer.

Frequently Asked Questions
Can I use a mobile selfie for SSC registration?
Only if it meets all requirements: plain light background, full face visible, no shadows, not blurry. A selfie taken in good natural light against a white wall can work. A selfie taken indoors in dim light with a cluttered background will be rejected at Document Verification even if the portal accepts the upload file.
My photo passed the portal upload but got rejected at DV — why?
Document Verification is a manual check. A staff member compares your photo against your appearance and the visual requirements in the notification. File size passing the portal check does not guarantee DV success. Ensure your photo has a plain background, full face visible, and was taken recently.
Do I need a new photo for each SSC exam?
Not always. SSC's One Time Registration (OTR) stores your photo centrally. Once registered, the same photo is used for all SSC exams until you choose to update it in your OTR profile.
What is the photo size for SSC GD Constable specifically?
SSC GD Constable requires a tighter 10–20KB limit compared to the 20–50KB range for CGL, CHSL, and MTS. Use the Compress to 20KB tool and target 18–19KB for GD Constable.
Does it matter if my photo is in colour or black and white?
SSC requires a colour photograph. Black and white photos are rejected at document verification.
