Step-by-step: prepare your image
- Capture or scan clearly. Use natural daylight or soft indoor light. Avoid harsh shadows, coloured bulbs and heavy filters.
- Crop to the right framing. Your head and shoulders should be comfortably inside the frame with a little space above the head. For signatures, crop to just the handwriting on white paper.
- Open the main PhotoResizer.in tool. Use the quick links in the header or go directly to the image resizer page.
- Select a suitable target KB value. If your notification states 20–50KB, you can safely start with 40–45KB to maintain clarity, or pick a lower option if the portal is very strict.
- Keep aspect ratio locked. This protects your picture from looking stretched when reduced to exam dimensions.
- Download and zoom in to verify. Open the final file, zoom in on your face or signature, and make sure edges remain sharp and text is readable.
Practical tips before final submission
Once your image is ready, a few small checks can save you from last-minute technical issues:
- Test the upload once on a desktop browser and once on mobile, if possible.
- Keep both the original and resized images in a clearly named folder so you can reuse them for future forms.
- Avoid editing the file further in apps that may enlarge it again or change the format.
