About Make image grayscale
Use grayscale image online to remove color from a picture while retaining intermediate gray tones. If you want to convert a photo to black and white in the everyday photographic sense, this produces a tonal grayscale version rather than a strict two-color threshold image.
How to make an image grayscale
- Select one or more supported color images.
- Select Process to apply the grayscale filter.
- Inspect the tonal result and download the image or batch ZIP.
A practical example
- Input
A color PNG illustration.
- Result
A PNG with gray tones in place of the original colors.
Grayscale conversion removes color information. Keep the color source if you may need it later.
Supported input and limitations
- This is not a black-and-white threshold, duotone, or selective-color editor.
- There is no brightness, contrast, or channel-mixing control. Output is re-encoded, not guaranteed to be a smaller file.
Image batches accept up to 100 files and 100 MB total. Source images must be within 12,000 pixels per edge and 48 megapixels. Batch results include a ZIP download.
Processing happens on your device. Read about local processing and optional workspace recovery.
Frequently asked questions
Is grayscale the same as a two-color black and white image?
No. Grayscale includes shades between black and white. A two-color image needs thresholding, which this tool does not perform.
Can I restore color after converting to grayscale?
The discarded colors cannot be reconstructed by this tool. Keep your original color image as a separate file.
