What Is Image Fill?
Image fill is an online tool that fills a selected area of a photo or image with a solid color. It's handy for hiding unwanted information, changing background colors, and creating design assets — anywhere you need to cover part of an image with color.
sakutto.ai's image fill tool processes everything in your browser — your images are never uploaded to any server. Safely mask personal information in internal documents or remove unwanted elements from images before publishing.
Freely choose fill colors and specify rectangular regions. Great for covering watermarks in screenshots, correcting document images, and editing images for social media posts. Free, no sign-up required.
Features of the Image Fill Tool
Bucket Fill
Click to fill a contiguous area of the same color. Adjust the tolerance to include similar colors in the fill.
Brush Fill
Paint freely by dragging your mouse or finger. Adjust the brush size for precision in tight areas.
Eyedropper Tool
Click anywhere on the image to pick a color and see its HEX and RGB values. Use the picked color directly as your fill color.
Undo / Redo
Easily undo and redo your changes — experiment freely until you get the perfect result.
Color Code Extraction
Copy the HEX or RGB values of any picked color with one click. Handy for design work and color matching.
Privacy Assured
All processing happens in your browser. Images are never sent to a server. Free to use, no sign-up required.
