Detailed research
Why compare LunaPic and TextFaker
LunaPic is a real online editor with a direct black-and-white action. It is especially relevant for users searching older online image effect tools and wanting a simpler, local-first alternative.
- Focus the page on grayscale conversion, not a full effect library.
- Use before/after images to make the result obvious.
- Document supported file formats and any metadata changes after export.
Implementation details
TextFaker can decode the image in the browser, draw it to a canvas, manipulate ImageData pixels, and export a new image file. That is a suitable open web standards approach for this utility.
Testing ideas
Tests includes representative pixel fixtures for black, white, primary colors, transparent pixels, and mixed tones. UI tests is designed to cover upload, mode switch, preview update, and download availability.
SEO notes
Include both grayscale converter and black-and-white image filter phrasing because users may use either term for the same desired output.
Research notes
- LunaPic's official editor URL exposes a black-and-white action, making it a real comparison target.
- The comparison focuses on user experience, local processing, and method clarity rather than overstating product capabilities.
- Because TextFaker's public license status is not established by this task, do not describe it as open source.
