Invalid image dimensions error on exam portal — fixed
"Invalid image dimensions" means your photo is the wrong pixel size. Each exam has specific width×height requirements. Cropping or scaling on your phone won't match exactly — use the resize tool.
Step-by-step fix
Find the required dimensions
Check the requirements table on your exam's page (link below). SSC requires 200×230px, RRB NTPC requires 320×240px, and so on.
Use the resize tool with exam preset
Select your exam — dimensions are auto-applied. Upload your photo and download the correctly sized output.
Verify before uploading
The download filename shows the dimensions (e.g. photo_ssc_200x230.jpg). This confirms the file is the right size.
Common causes and fixes
Photo is wider/taller than required
Tool auto-crops the center of your photo to match the target ratio, then resizes to exact px.
Photo is smaller than required
Tool upscales to the target dimensions. For best quality, use a photo that is at least as large as the requirement.
Aspect ratio mismatch (e.g. square vs portrait)
Tool handles this — it center-crops to the correct ratio before resizing.
Frequently asked questions
What does "invalid image dimensions" mean on an exam form?
It means the portal checked the pixel width and height of your uploaded photo and found they don't match the requirement. For example, you uploaded 400×500px but the form needs 200×230px.
How do I resize a photo to exactly 200×230px?
Use the SSC exam preset in the photo resize tool. It automatically resizes to 200×230px and compresses to 20–50KB.
