Comprehensive Guide & Reference

Total Watermark, Text & Logo Erasure

Completely erase logos, text stamps, and watermarks without leaving residual outlines or discolored boxes.

Permitted use: Only remove watermarks, logos, signatures or credits from images you own or are authorised to edit. Removing attribution you do not own may infringe copyright.

1. Smart Continuous Gaussian Inpainting

Our client-side engine uses Smart Continuous Gaussian Inpainting. It completely discards original pixels inside your painted mask and applies a continuous Gaussian distance falloff across clean background pixels so zero outline rings or step lines appear.

The algorithm calculates median background color statistics around the perimeter to penalize logo border lines or thin banner strips. It casts 32 rays, applies linear distance decay, and performs 5 passes of PDE Laplacian smoothing to produce seamless background gradients.

2. Mask-Composited AI Neural Engine

For complex photographs and detailed textures, the AI engine uses deep learning inpainting models. Only the masked region is reconstructed and composited with a soft alpha border, preserving 100% of your original photo resolution.

Real example

Worked example: cleaning a center logo off a photo

Input
stock-preview.jpg · 1200×800 · centered semi-transparent logo
Output
→Clean image · logo area reconstructed by AI inpainting · best results on solid or low-texture backgrounds

Inpainting fills the marked area with plausible content — flat walls and skies disappear cleanly, while intricate textures may show artifacts. Only remove watermarks from images you have rights to.

Privacy & data handling

This tool is not fully browser-local: to produce its result it contacts a server, so your input leaves your device. We do not keep your prompts or outputs and do not use them for training. The sections above describe exactly what this tool does with your input. See our privacy policy.

Frequently Asked Questions

How do I remove text, logos, or numbers from an image seamlessly?
Upload your image, select the Brush or Box tool, and paint completely over the text, logo, or number. Click Remove Watermark and our Smart Inpainting algorithm erases 100% of the marked area without dark outline rings.
What is the difference between Smart Inpainting and AI modes?
Smart Inpainting runs locally in your browser — 100% private, instant, and guaranteed to erase text and logos completely without uploading your files. AI Mode connects to cloud neural inpainting models.
Will removing a logo or number blur the rest of my photo?
No! 100% of your original image resolution and sharpness is preserved. Only the exact masked region is erased and filled with surrounding background colors.
Is it completely free and are there usage limits?
Yes! It is 100% free with no account required, no added watermark on export, and unlimited usage.
Are my photos private and secure?
In Smart Inpainting mode nothing leaves your device — all processing occurs inside your web browser. In AI mode your image is transmitted securely over HTTPS solely to process the inpainting request.
