How to Fix TNPSC "Invalid Photo Dimensions" & "File Size Exceeds 50KB" Errors (2026)
If you have ever filled an application form on the official Tamil Nadu Public Service Commission (TNPSC) portal (tnpsc.gov.in), you have probably encountered one of the frustrating red error popups right when you hit the upload button.
The One Time Registration (OTR) validation script is extremely strict. If your photo is even one pixel off from the required 275px X 354px aspect ratio, or if your file size is 51 KB instead of the maximum 50 KB, the system will immediately reject the upload.
In this practical troubleshooting guide, we explain exactly why these errors happen on smartphone cameras and how to fix them in 10 seconds without paying browsing center charges.
The 3 Most Common TNPSC Photo Upload Errors
Why it happens: Modern smartphone cameras take pictures in standard photographic ratios such as 4:3 or 16:9 (e.g., 3000px X 4000px). The TNPSC portal specifically checks for a 3.5cm X 4.5cm ratio (275px X 354px). If the aspect ratio does not match this calculation, the upload fails.
Why it happens: High-resolution mobile phone photos are usually 2MB to 6MB (2000KB - 6000KB). Uploading raw photos triggers an instant size rejection. Conversely, if you send an image over WhatsApp multiple times, it might drop below 20KB, which is also rejected for being too blurry.
Why it happens: iPhones save photos in HEIC format, while screenshots are saved as PNG files. The TNPSC OTR server only recognizes standard JPEG/JPG format.

Pre-Upload Final Checklist
Before submitting your application on the TNPSC website, double-check these 4 points:
- ✅ Background: Is it completely plain white? (Scenery, selfie angles, or blue backgrounds are rejected).
- ✅ Date Validity: Is the printed date within the last 3 months of the exam notification date?
- ✅ Signature Handwriting: Did you sign in natural running cursive handwriting? (Full capital letters like "K. ARUN" will result in application disqualification).
- ✅ File Name: Ensure your file name is simple without special characters (e.g.,
tnpsc_photo.jpginstead ofphoto#1(copy).jpg).
