Limits
- Presets are common sizes only: check your form's current rules, because requirements vary by exam, institution and country.
- Clean background pushes near-white paper to pure white and keeps ink. Strong settings can thin faint strokes, so check the result.
- Trim removes blank margins before fitting; it needs a mostly plain light background.
- If the KB window cannot be met, the best file is still returned and marked “not within range”.
