20 KB is small — plan for a resize
A full phone photo cannot reach 20 KB without looking rough. First scale the image down to the pixel size the form actually needs — often around 200 x 230 pixels for a passport-style photo — then compress. That combination reaches 20 KB while keeping the face clear.
Steps that work
- Crop to just the head and shoulders.
- Resize to the form's stated dimensions.
- Compress, check the size, and nudge the dimensions down again if you are still over.
Where 20 KB limits show up
Exam applications, recruitment forms and government services often ask for a photo between 10 and 50 KB and a signature between 10 and 20 KB, each with fixed pixel dimensions. Always follow the exact numbers in your form's instructions - they differ between portals.
Common reasons a photo is rejected
- Saved as PNG or HEIC instead of JPG/JPEG (JPG and JPEG are the same format).
- Correct KB size but wrong pixel dimensions.
- Too dark, blurred or cropped too tightly after heavy compression.
