This page opens with the black-and-white filter already applied, so your photo turns grayscale the moment you load it. Colors are converted using perceptual luminance weights, which keep the brightness relationships the eye expects: green foliage stays lighter than red flowers of the same intensity, and skin tones keep natural shading.
A plain conversion can look flat, so the sliders let you add contrast for a bolder look, lift or deepen the overall brightness, add a vignette, or warm the result with a little sepia for a classic darkroom tone. Grayscale is also useful for documents and scans you want to print cheaply. Conversion happens on your device; nothing is uploaded.

Getting a striking black-and-white photo
Black and white rewards strong light, shapes and texture rather than color. Scenes with clear shadows, dramatic skies, old buildings, portraits with side light and street scenes often convert well. A photo whose only interest is its color, such as a sunset, may look dull in grayscale.
After converting, raise contrast until the darkest areas are close to black and the brightest close to white; this gives the full tonal range that classic prints have. A light vignette draws the eye to the center, and a small amount of sepia gives a warm, archival feel.
Frequently asked questions
Is grayscale the same as black and white?
In everyday use, yes. A “black and white” photo is really grayscale: it uses many shades of grey between black and white, not just the two colors.
Will the file get smaller?
Often slightly, because there is less color information to store, but the file is saved as a normal color JPG, PNG or WebP that every app can open.
Can I convert a scanned document to grayscale?
Yes. Converting scans to grayscale and adding contrast makes text darker and backgrounds cleaner, which helps when printing.
Can I go back to color?
Set the grayscale slider to zero or choose the Original preset before downloading. Once a grayscale file is saved, the color cannot be recovered from it, so keep your original.
