Features
Image Mode
Upload any JPG or PNG (up to 10 MB). Esther preserves the original composition 100% while replacing colors and surface materials using Canvas-based pixel processing. Supports transparency preservation for PNG files with alpha channels.
Icon Mode
Browse or search over 10,000 icons from the React Icons library — including Font Awesome, Material Design, Ant Design, Bootstrap Icons, Feather, and more. Filter by collection, then apply any color + material combination.
Line Art Mode
Converts uploaded photos into high-contrast black-and-white illustrations using edge detection algorithms. Choose from Woodcut/Engraving, High Contrast B&W, Pencil Sketch, or Edge Detection styles. Adjust threshold and noise reduction for fine control.
Color Palette (1,000+)
Esther ships with 1,000+ colors including 40 hand-curated Pantone-inspired swatches and 960 programmatically generated colors spanning 24 hues × 8 saturation levels × 5 lightness levels. Use the search bar to find colors by name, Pantone code, or hex value.
Material Effects
Apply surface presets including Chrome, Matte, Glossy, Metallic, Satin, Brushed Metal, Gold, Rose Gold, and Glass. Fine-tune Brightness (50–200%), Contrast (50–200%), and Saturation (0–200%) with real-time preview sliders.
Export & Download
All exports are 500 × 500 px PNG files. The Canvas renderer applies all color and material transformations client-side before download — no file is uploaded to Esther servers. Each download consumes 1 credit from your account balance.
