FAQ
- How does the grayscale conversion work?
- Each pixel is converted to a balanced shade of gray based on its color brightness.
- Are my images uploaded?
- No. The effect is applied locally in your browser and the file stays on your device.
- Can I get the original color back?
- Not from the grayscale copy, so keep your original if you may need the colors later.
- What is grayscale good for?
- Print-friendly versions, a uniform look across photos, or reducing visual noise.
- Does it work on transparent PNGs?
- Yes, transparency is preserved while the visible pixels turn gray.
- Will the file get smaller?
- Often slightly, since gray images compress a little better than full color.
