The Union Public Service Commission (UPSC) Online Recruitment Application (ORA) portal is infamous among candidates for its extremely sensitive image upload system. You may have the perfect photograph, but the moment you click "Upload," you are hit with red text stating "Invalid DPI" or "Resize Image - Dimensions must be 350x350."

Here is a complete breakdown of why these specific errors occur on the UPSC server and how to bypass them instantly.

1. Error: "Dimensions must be 350x350 pixels"

Unlike almost every other exam portal in India that requires rectangular passport photos, the UPSC requires a perfectly square image for both the photograph and the signature.

• The Rule: The width and height must be identical. The minimum allowed is 350 pixels by 350 pixels, and the maximum is 1000 pixels by 1000 pixels.
• The Fix: Never try to manually "stretch" a rectangular photo into a square, as it will distort your face and lead to rejection. Instead, use a cropping tool that locks the aspect ratio to 1:1.

2. Error: "Invalid DPI Detected"

This is the most frustrating error because "DPI" (Dots Per Inch) has nothing to do with file size or pixels. DPI is a print metadata tag embedded inside the JPEG file.

• The UPSC portal often strictly checks if the EXIF data of the image states the resolution is exactly 300 DPI.
• Mobile phone cameras save images at 72 DPI or 96 DPI by default. Even if the KB size is correct, the missing 300 DPI tag triggers the error.
• The Fix: Go to the Fix 200/300 DPI Tool on our homepage, select "300 DPI", and upload your photo. The tool will inject the correct metadata without altering the visual quality of your image.

3. Error: "Bit Depth must be 24-bit"

Occasionally, candidates scanning their signatures in "Grayscale" or "Black & White" mode on their home printers will receive a bit-depth error.

The UPSC portal requires a standard 24-bit RGB True Color image. If you scan in grayscale, the scanner outputs an 8-bit image. To fix this, always ensure your scanner settings are set to "Color" (even for a black ink signature), or run the image through our standard resizer, which automatically re-encodes all outputs to standard 24-bit RGB JPEGs.
