| Local privacy | Our workflowBrowser-local conversion for supported PNGs. | Proprietary workflowtoWebP.io also advertises no uploads and private local conversion. | Privacy is parity, not a differentiator against this product. |

Detailed research
Why compare
toWebP.io is a strong browser-local competitor and is handled carefully. Since it already advertises no uploads, TextFaker's comparison focus on PNG-only SEO fit, output validation, and consistency with the existing TextFaker converter family.
- Do not claim all competitors upload files.
- Treat bulk and multi-format input as toWebP.io strengths.
- Keep TextFaker's page narrow and verifiable.
Implementation Notes
The acceptance tests listed in the request map directly to this comparison: output MIME image/webp, .webp filename, preserved dimensions, generated Blob, deterministic copy/download text, transparent PNG handling, and quality slider behavior.
- Do not add size scaling to this dedicated page unless requested.
- Ensure quality changes create new output state.
- Keep transparent PNG alpha intact.
Generated Image
Use a generated image showing a single PNG asset in a focused TextFaker-style panel, with a background hint of a larger batch queue to represent the comparison.
- No toWebP.io branding.
- Make PNG-only scope obvious.
Content Risks
Because toWebP.io advertises local browser conversion, any broad claim that TextFaker is safer because competitors upload files would be false for this comparison.
Research notes
- Official toWebP.io page says it batch converts JPG, PNG, GIF, SVG, ICO, BMP, and AVIF to WebP.
- The page explicitly says conversion is directly online in the browser with no uploads and files stay private, so TextFaker not claim privacy uniqueness here.
- The page includes quality percentages and size scaling controls, making it a strong benchmark for quality slider behavior.
- Generated image: PNG-only verified converter page next to a generic multi-format batch queue.
