FAQ

Frequently asked questions

Everything you need to know about removing Gemini AI watermarks and compressing images with TinyJPG.co.

Is my data safe?

Absolutely. We process images directly in your browser session and automatically delete them immediately after processing. We do not store, view, or share your uploads. When you close the tab, your images are gone — we follow a strict Zero-Data policy.

Is this tool really free?

Yes, TinyJPG is 100% free to use. You can remove Gemini AI watermarks and compress as many images as you like without any hidden fees or subscriptions.

Does this remove the invisible "SynthID" watermark?

Yes. Google Gemini uses a technology called SynthID to embed invisible watermarks into the pixels of generated images. Our tool is designed to disrupt and remove this data structure so your image is truly clean.

How does the Gemini watermark remover work?

Google Gemini applies watermarks using standard alpha compositing. TinyJPG.co reverses this formula using reverse alpha blending to mathematically recover the original pixel values — producing a pixel-perfect restoration with zero quality loss.

What image formats are supported?

TinyJPG.co supports JPEG, PNG, and WebP — the most common output formats from Google Gemini and other AI image generators. You can upload multiple images at once for batch processing and download them individually or as a ZIP file.

Can I compress images without removing the watermark?

Yes! TinyJPG.co offers both watermark removal and image compression as separate or combined features. Toggle compression on or off and adjust the quality slider from 10–100% to balance file size with visual quality.
