- Do not overstate LunaPic upload or privacy behavior without a source.
Feature Gap
TextFaker's biggest distinction is measurement before conversion: users can know whether a file actually had transparency.
- All-opaque images does not trigger paywall value flow.
- Transparent images show conversion stats and downloadable output.
SEO
The comparison can target users asking how to remove existing transparency and make image opaque.
- Include transparent GIF caveat if TextFaker does not support animation.
- Keep PNG as the central page intent.
Testing
Generated test images include a transparent logo, a semi-transparent drop shadow, and an all-opaque JPEG.
- Verify all-opaque source returns informational result.
- Verify semi-transparent pixels blend with matte.
Research notes
- Official LunaPic FAQ says transparency can be removed by setting a background color or image to fill it in.
