About Grayscale Image
Remove all color from an image, producing a classic black-and-white photograph. Adjust intensity from subtle desaturation to full grayscale. All processing happens in your browser — images never leave your device.
How It Works
This tool uses the browser's native Canvas CSS filter to apply a grayscale conversion. The image is drawn onto a canvas with the grayscale() filter at your chosen intensity, then re-encoded as JPEG, PNG, or WebP.
Step by Step
- 1 Upload a JPEG, PNG, or WebP image
- 2 Adjust the intensity slider (0% = no change, 100% = full grayscale)
- 3 Click Convert to apply the grayscale effect
- 4 Download your black-and-white image
Tips
- 100% intensity removes all color for a true black-and-white result.
- Try 40-60% for a subtle desaturated look popular in modern photography.
- Grayscale images often compress better as JPEG due to fewer color channels.
- Pair with the Adjust tool to increase contrast after converting to grayscale.
Frequently Asked Questions
What is the difference between grayscale and black-and-white?
In digital imaging, grayscale and black-and-white are often used interchangeably. Both refer to images with only shades of gray, from pure black to pure white, with no color information.
Can I adjust how much color is removed?
Yes. The intensity slider controls the degree of desaturation. At 50% you get a partially desaturated image; at 100% all color is removed.
Does this reduce file size?
Grayscale images can compress better in JPEG format since there is less color data to encode. The file size change depends on the image content.
