Why DeGemini
Mathematical watermark removal, not AI inpainting.
Private by design
Every pixel is processed on your device with the Canvas API. Nothing is uploaded, stored or shared — the tool keeps working even offline.
Truly lossless
We invert Gemini's exact alpha-blending formula instead of blurring pixels away, restoring the original image with zero quality loss.
Free, unlimited
No credits, no subscriptions, no sign-up. Remove as many watermarks as you like, as often as you like.
