FAQ
Are my images sent to a server?
No. The grayscale conversion happens entirely in your browser using the HTML canvas. Your images stay on your device and are never uploaded.
Which image formats are supported?
Common web formats such as JPG, PNG and WebP are supported. The converted image can then be downloaded directly from the tool.
Does the conversion reduce image quality?
No, the resolution stays the same: only the colors are converted to shades of gray. The file size may vary slightly depending on the export format chosen.
