Typical size requirements
Photo: 20 kb to 50 kb, JPG, passport-size, light background.
Signature: 10 kb to 20 kb, JPG, signed on white paper with a black or blue pen.
Some forms ask for specific pixel dimensions (e.g. 200×230 for photo).
How to resize
Crop the photo or signature so there is no extra white space around it.
Reduce the dimensions and JPG quality until the file fits the kb range.
Check the final file size before uploading — re-do if it is outside the range.
