Frequently Asked Questions
What is grayscale conversion?↓
Grayscale conversion removes color information, converting each pixel to a shade of gray based on its luminance. The result is a black and white image.
Does converting to grayscale reduce file size?↓
Yes. Grayscale images contain less color data so they compress more efficiently. Run through our compressor after conversion for maximum size savings.
Can I convert a color image to grayscale without quality loss?↓
The spatial resolution is fully preserved. Grayscale only removes hue and saturation. The output has the same sharpness and detail as the original.
What image formats support grayscale output?↓
All formats are supported: PNG, JPEG, WebP and AVIF. PNG and WebP produce the best grayscale results due to lossless or near-lossless compression.
