Grayscale Image
Create a balanced black-and-white image using weighted luminance.
This tool uses the weighted formula 0.299R + 0.587G + 0.114B to match human brightness perception.
PNG output preserves transparency; JPG output is ideal for smaller photographic files.
About this tool
PixEasy converts color images into balanced grayscale using weighted luminance, a method that reflects how people perceive the brightness of red, green, and blue. Use it to create black-and-white portraits, simplify graphics, prepare reference images, check visual contrast, or give a photograph a classic monochrome appearance. The live preview lets you compare the result before downloading it as PNG or JPG. JPG, PNG, and WebP files are supported, and transparent PNG pixels remain transparent when you choose PNG output. All conversion work runs locally in your browser through the Canvas API. PixEasy does not upload, inspect, or store your image. There is no account requirement, payment, or watermark, so you can make a private grayscale image in seconds.
Common Questions
- How does PixEasy create a grayscale image?
- It uses weighted luminance so the grayscale result matches perceived brightness more accurately than a simple channel average.
- Can I make a PNG black and white?
- Yes. Upload a PNG and download the grayscale result as PNG to preserve transparency.
- Are my photos private?
- Yes. Processing happens locally in your browser and your files are not uploaded.
- Can I switch between grayscale and invert?
- Yes. Use the Color effect options to compare Original, Invert, and Grayscale.
