Which forms need a file under 10 KB

None of the exams we list asks for exactly this size right now, but many state and university forms do. Check the limit printed in your notification and pick the closest size at or below it.

Getting a clear image under 10 KB

• Crop tightly. At this size most of the bytes should go on the ink or the face, not on empty paper or wall.
• Keep the pixel size modest. A signature at about 280 × 120 pixels, or a small photo at about 200 × 230, fits easily and still looks sharp on the portal.
• Use good light. A shadowy phone photo has grainy patches that take up space and look smudged once compressed.
• If the form also sets a minimum size, such as 10 KB, the tool keeps the file above it as well.

Is 1 KB 1000 or 1024 bytes?

Portals differ, so this tool stays under the limit by either definition. The file always fits.
