What is the difference between pure grayscale and black and white?

Pure grayscale preserves all intermediate shades of gray between 0 (black) and 255 (white). High-contrast Black & White boosts contrast so light tones turn crisp white and dark tones turn deep rich black.

Will converting my image to black and white reduce its resolution?

No. The exported image preserves 100% of the original pixel dimensions and resolution of your uploaded file.

Can I add a warm sepia tone to my black and white photo?

Yes. Use the Sepia slider to blend warm brownish-amber vintage tones reminiscent of early 20th-century photography.

Are my uploaded photographs stored on any server?

No. Everything is rendered locally inside your web browser using HTML5 Canvas. Your photos never leave your device.

Which image formats are supported?

You can upload and convert PNG, JPG, JPEG, WebP, AVIF, BMP, and SVG images.
