Best use cases for a 15KB image
15KB is tiny, so the page should guide users toward realistic output and cleaner source images.
Strict Upload Limits:
Use this page when a portal specifically rejects anything above 15KB.
Better for Small Images:
Signatures, headshots, icons, and small ID photos work better than large detailed photos at this limit.
Crop Before Compressing:
Remove blank space first so the remaining subject gets more of the available file size.
Private Processing:
Your file is compressed on your device, which helps protect personal document images.
