Platform-Specific Guides

Grok (xAI)

Tip: Select "Grok" from the platform dropdown for best results.
Doubao (豆包)
Reverse Screen Blending"豆包AI生成" white text in bottom-right

Google AI Studio

Tip: Auto-detect handles this perfectly — same engine as Gemini.
Tips for Best Results
Use PNG for Best Quality
PNG images produce the best results because they have no compression artifacts. JPEG images still work well but may have slightly less precision in the watermark region.
Select Platform Manually for Doubao
The auto-detect feature is optimized for Gemini. For Doubao (豆包) images, manually selecting "Doubao" from the dropdown ensures the correct algorithm is used.
Check the Before/After Slider
Always verify the result using the before/after comparison slider. In rare cases with very dark backgrounds, you may notice minor artifacts.
Original Files Are Never Modified
The tool creates a new clean copy. Your original uploaded file is never altered or stored anywhere.
