What is the Image Editor?
The Image Editor is a client-side graphics utility designed to edit, rotate, crop, and apply filters to your images directly inside your browser. By adjusting filters and applying transforms locally, you can modify photographs and graphics without installing heavy editing software.
This editor uses HTML5 canvas and hardware-accelerated CSS filters to render changes in real-time. Because all operations are executed in browser RAM, your personal photographs, business charts, and sensitive documents are never uploaded to a server.
How to Use the Image Editor
- Upload Your Image: Drag and drop your image file into the upload block, or click the box to browse and import a file from your system.
- Adjust Visual Filters: Drag the sliders in the sidebar to fine-tune brightness, contrast, saturation, grayscale, sepia, blur, and hue rotations.

- Click the "Apply Crop" button to crop the canvas to those coordinates.
