Image Editing Tool Suite — Pixelation, Grayscale, Palette Extraction, Crop
Image Editing Tools
Edit your images directly in the browser — no software installation required.
Grayscale Converter
Convert color images to black and white. Choose from multiple conversion methods (average, luminance-based, desaturation).
Grayscale Converter
Essential Aesthetics
Remove color to emphasize the essential forms and contrast.
Pixelation Tool
Transform images into a pixel art style. Great for retro game aesthetics, mosaic effects, or creative privacy masking.
Image Pixelator
Privacy & Expression
Pixelate images to protect privacy or create an artistic pixel-art look.
Image Quality Adjuster
Control JPEG compression level to optimize the balance between image quality and file size. Ideal for reducing images before web upload.
Image Degrader (Retro Meme)
Internet Archaeology
Intentionally degrade images to create that 20-year-old internet meme aesthetic.
Color Palette Extractor
Automatically extract dominant colors from any image. Useful for identifying brand colors, finding design inspiration, or analyzing photo color profiles.
Color Palette Extractor
Nature's Color Theory
Discover natural color combinations from your photos.
Image Cropper
Crop any region with precision. Fixed aspect ratio cropping is supported.
Image Cropper
Framing Perfection
Crop images to standard aspect ratios like 3:2, 16:9, and 1:1.
Image Metadata Viewer
Read the EXIF metadata embedded in your image files — capture date, camera model, GPS coordinates, and more.
Image Metadata Viewer
Hidden Data Forensics
Explore hidden shooting info and EXIF data inside your image files.
Comprehensive Image Processor
Adjust brightness, contrast, saturation, and hue all in one integrated tool.
Image Optimizer
Speed & Quality Balance
Compress image size and convert between formats (WebP, JPEG, PNG).
Grayscale Conversion Methods Compared
| Method | Formula | Characteristics |
|---|---|---|
| Average | (R+G+B)/3 | Simple, fast |
| Luminance-based | 0.299R + 0.587G + 0.114B | Optimized for human vision |
| Desaturation | (max+min)/2 | Midpoint method |
Recommendation: For converting photos to black and white, the luminance-based method produces the most natural results. The human eye is most sensitive to green and least sensitive to blue — this formula reflects that perceptual reality.
Tips for Creating Pixel Art
- Use a large pixel size: The bigger the pixel block, the more retro the result
- Choose the right source image: Simple, high-contrast images convert to pixel art more effectively than complex ones
- Limit the color palette: Fewer colors create a more authentic pixel art aesthetic
EXIF Metadata and Privacy
Before sharing photos on social media or any public platform, we recommend checking the metadata.
Smartphone photos frequently contain GPS location data. If you’d rather not expose your home or workplace coordinates, check and remove the EXIF data before uploading.
