Frequently Asked Questions

What conversion modes are available?

Three modes: Grayscale converts to true black-and-white using ITU-R BT.709 luminance weights. Threshold converts to pure black or white based on a brightness cutoff. Sepia adds a warm vintage tone.

Can I process multiple images at once?

Yes. Upload multiple images and they will all be converted with the same settings. Each image shows a before/after preview, and you can download all results at once.

What does the intensity slider do?

The intensity slider blends between the original color image (0%) and the fully converted result (100%). This lets you create partial desaturation effects or subtle sepia tones.
