Detailed research
Why Choose TextFaker
Use TextFaker when the image has already been saved and the user needs to know whether transparency survived. The checker should answer this immediately with exact pixel evidence.
- Check PNG and GIF-style transparent assets after editing.
- Find opaque files that only look transparent.
- Measure how much of the image is transparent.
When LunaPic Fits Better
LunaPic is better when the user needs to create or edit transparency. If TextFaker reports that the file is fully opaque, an editor is the next step.
- Use LunaPic to add transparency to simple backgrounds.
- Use LunaPic to modify the image itself.
- Use LunaPic when a new output file is needed.
SEO Notes
The page should target image transparency checker terms and present LunaPic as an editor users may have used before checking the result.
Test Notes
Include tests that ensure the tool does not infer transparency merely from a PNG extension. A PNG with all alpha 255 should be reported as fully opaque.
- Opaque PNG fixture.
- Transparent PNG fixture.
- Fake checkerboard raster fixture.
Research notes
- LunaPic official help says it fully supports image transparency and offers ways to add it.
- The help page notes that saving as GIF or PNG preserves transparency.
- LunaPic is proprietary software; TextFaker should be presented as a browser-based transparency checker, not an open-source editor.
