Common mistakes to avoid
- Assuming bigger means clearer — padding adds size, not detail
- Uploading a PNG when JPG is required
- Padding far beyond the minimum needed
Pro tips
- Only pad up to the minimum the portal asks for
- Start from the best-quality original you have
- If the portal also has a maximum, keep within both bounds

Frequently asked questions
How do you increase a file to 20 KB?
ExamKB safely pads the file up to 20 KB so it passes a "file too small" check while still opening normally everywhere.
Is my image uploaded?
