FAQ
What is the difference between grayscale and black-and-white?
Grayscale keeps 256 shades from black to white — it is not a pure binary image. You get rich layered black-and-white photos.
Can I restore colors after conversion?
No — color information is lost. Keep your original file safe.
What does grayscale intensity mean?
It controls the desaturation level. 100% is full black-and-white, 50% keeps some color for a partially faded look.
What image formats does this tool support?
This tool supports common formats including JPG, PNG, WebP, GIF, and BMP. Input and output formats depend on the specific operation.
What is the maximum image size?
Most operations support images up to 10MB or 4000x4000 pixels. Larger images may be automatically scaled down.
Are my images uploaded to a server?
No. All image processing happens locally in your browser using Canvas API. Your images never leave your device.
