Tips for best results
- Grayscale files are often smaller, which helps when you must print many pages cheaply.
- Everything runs in your browser, so you can use Image Grayscale even on a slow connection once the page has loaded.
Limits to keep in mind
- Files are processed in your browser, so very large files depend on your device memory and may be slow. The limit is 50 MB per file.
- Animated images keep only their first frame. JPG output cannot keep transparency, and lossy formats discard a small amount of detail.
