Every adjustment, from exposure correction to spot healing, happens locally on your computer or phone, ensuring your photos remain completely private.

Professional Features, Zero Cost

This free photo editor includes tools typically found only in premium software like Adobe Lightroom or Photoshop:

  • Light & Exposure Controls: Fine-tune exposure, contrast, highlights, shadows, whites, and blacks to perfect your image's tonal range.
  • Color Grading: Adjust temperature, tint, vibrance, and saturation to achieve the exact color mood you envision.
  • Detail Enhancement: Apply clarity for midtone punch, texture for fine detail, and sharpening for crisp edges.
  • Atmospheric Corrections: Use dehaze to cut through fog or haze in outdoor shots.
  • Creative Effects: Add vignettes to draw attention to your subject.
  • Noise Reduction: Reduce digital noise from high-ISO photos while preserving detail.

Selective Editing with Masks

Unlike basic online editors, our tool supports local adjustments using masks—a feature typically reserved for professional software:

  • Rectangular Masks: Perfect for adjusting specific regions like the sky or foreground.
  • Radial Masks: Create spotlight effects or selectively adjust around your subject.
  • Linear Gradient Masks: Ideal for graduated filters, like darkening a bright sky while keeping the landscape properly exposed.

Each mask can have its own unique adjustments for exposure, contrast, color, clarity, and more—giving you precise control over every part of your image.

Spot Healing & Dust Removal

Remove unwanted elements from your photos with our intelligent spot healing brush. Whether it's sensor dust spots, skin blemishes, or small distractions, simply paint over them and watch them disappear. The "Visualize Dust" feature highlights potential spots by analyzing contrast patterns, making cleanup faster and more thorough.
