FAQ

Frequently Asked Questions

My photo came out tinted with color instead of black and white. What happened?

You likely picked the overlay option. Step two offers a color overlay or black and white — the guide even demos a pink overlay later on. Choose black and white and process the image again.

Do I need to sign up before converting an image?

No signup. Like Zight's other browser tools, it's free and handles the photo locally on your device, so the image is never uploaded.

Can I save the result as a JPEG instead of a PNG?

Yes — the output step offers both PNG and JPEG. Pick one, click 'Process Image', and download. You can also tweak the overlay or opacity and process it again.
