Gemini generates high-quality images suitable for many professional uses. But getting them ready for real-world use requires a few steps — starting with the watermark.
Step 1: Remove the visible watermark
The sparkle icon in the bottom-right corner is fine for personal use, but it looks out of place in polished designs. Use Lumina Watermark to remove it cleanly before taking the image anywhere else.
Step 2: Export at the right format
Lumina exports as PNG, which is lossless and suitable for print or high-resolution digital use. If you need JPEG for web performance, convert after downloading.
Step 3: Resize for your use case
- check_circleWeb hero images: 1920×1080px, compressed JPEG or WebP
- check_circlePresentation slides: 1280×720px PNG works well
- check_circlePrint: use the original resolution, check DPI requirements
- check_circleSocial media: check each platform's recommended dimensions
Step 4: Consider disclosure
Even without the visible watermark, SynthID remains embedded in the image. If transparency about AI-generated content matters in your context — journalism, advertising — disclose it separately.
