Grayscale Converter vs LunaPic
Grayscale Converter is the baseline in this comparison: Convert an uploaded image to grayscale in your browser, compare the original and converted result, then download the black-and-white output without sending the file to a server.

Detailed comparison
Legacy Competitor
LunaPic has long-standing visibility for quick online photo effects. The comparison respects that utility while showing how TextFaker provides a more focused local workflow.
- Do not frame LunaPic as obsolete.
- Emphasize interface focus and privacy.
UX Opportunity
A modern drop zone, clear selected-file state, and side-by-side output preview will be more approachable than navigating a large legacy editor.
- Use clear error states for unsupported files.
- Keep controls compact.
- Make download state obvious.
Technical Content
TextFaker explains that grayscale keeps shades of gray while not being the same as thresholded pure black and white.
- Include black-and-white versus grayscale distinction.
- Mention alpha handling where relevant.
- Mention browser format support limitations.
Risk
Canvas decoding and export behavior can vary by browser and format. The implementation handles decode errors gracefully and avoid promising every possible image format.
- Support common raster formats first.
- Use feature checks for export types.
- Show a clear unsupported-format message.
Research notes
- LunaPic support describes a straightforward upload and process flow for black-and-white conversion.
- The comparison focuses on workflow and local processing rather than unverified quality claims.
- LunaPic is useful as an adjacent online editor competitor even if it is not a formula-focused converter.
