About Object Remover

OptiPix Object Remover lets you paint over unwanted objects, people, text, watermarks, or blemishes — and a fast browser-side inpainting algorithm fills the painted area with realistic surrounding pixel content. Brush size and hardness are adjustable. Use the rectangle selection tool for large objects or the eraser to fix mistakes. Undo / redo per stroke. Two inpainting methods are available: Telea fast marching (great for small objects on simple backgrounds) and Navier-Stokes diffusion (slower but better for textured areas like grass and bricks). Zoom and pan for precision. Download as JPEG, PNG, or WebP. HEIC input and clipboard paste are supported. Everything runs in your browser — your photos never leave your device. The free alternative to Photoshop's Content-Aware Fill and Spot Healing Brush.

How It Works

Your brush strokes build a binary mask. The Telea fast-marching method propagates pixel values inward from the mask boundary using a weighted average of known neighbors guided by image gradients. Navier-Stokes diffusion is available as a slower, gradient-respecting alternative.

Use Cases

  • •Remove a stranger from your vacation photo
  • •Erase a date stamp from an old photo
  • •Remove a watermark from your own photo
  • •Erase a blemish or stray hair from a portrait
  • •Remove power lines or trash from a landscape shot

Frequently Asked Questions

How well does it work?
OptiPix uses a Telea fast-marching inpainting algorithm that gives clean results on small to medium objects with reasonably uniform backgrounds (sky, grass, walls, water). For complex textures or very large removals, results vary.
Is this AI-powered?
The current version uses classical inpainting (Telea / Navier-Stokes) running in pure JavaScript on a canvas. It's fast and runs offline. We may add LaMa ONNX inference as an optional model in the future.
Are my photos uploaded?
No. Brush strokes, masks, and inpainting all run on a local canvas. Your photos never leave your device — important for personal photos with people in them.
How do I undo a brush stroke?
Press Ctrl+Z (or Cmd+Z on Mac) to undo. Each stroke is its own undo step. Use Ctrl+Shift+Z to redo.
Can I remove a watermark?
Only watermarks on images you own or have explicit permission to modify. Don't use this to violate copyright.
