Convert an Image to Black and White
Convert a photo to black and white and tune how strong the result looks — from a gentle desaturation to a hard, high-contrast noir. Everything runs on your device; your images are never uploaded.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
Not every black and white is the same
Draining the color out of a photo is the easy part; making the result look good is the interesting part. A straight desaturation often lands flat and gray, because the color that was carrying the picture is gone and nothing has replaced it. That is why the B&W look here raises contrast slightly at the same time, and why the Noir look pushes contrast much harder and darkens the whole frame for a dramatic, high-key-shadow result.
You are not locked into either. The black & white slider runs from 0 to 100%, so you can stop halfway for a muted, partially desaturated look, then use the contrast and brightness sliders to place the tones exactly where you want them.
Where monochrome earns its keep
Black and white removes a variable. Portraits stop competing with a distracting shirt color, architecture reads as shape and light, and scanned documents or receipts become easier to read once a yellowed page turns neutral. It is also the standard fix when a photo was shot under mixed lighting whose color cast is impossible to correct convincingly.
Because the conversion is just a rendering choice, nothing is destroyed: your original file stays as it is on disk and the black and white version downloads as a new image.
One photo or the whole folder
Drop in a single picture or a batch — the same conversion applies to all of them, which is what you want when a set of product shots or a gallery has to look consistent. Hold the compare button to flip back to the color original at any point, then export as JPG, PNG or WebP, individually or together as a ZIP. The images never leave your browser.
Frequently asked questions
- Is my image uploaded to adjust it?
- No. Every adjustment is computed on a canvas inside your browser, so the photo never leaves your device and no server ever sees it.
- How do I make an image black and white?
- Set the “Black & white” slider to 100% — or click the B&W look, which also adds a little contrast so the result does not look flat. Noir goes further with a much harder contrast curve.
- What does inverting the colors do?
- It replaces every color with its opposite, which turns a photo into a negative: white becomes black, blue becomes orange. It is how you read a scanned film negative, and a quick way to flip a screenshot to a dark version.
- What is the difference between brightness and contrast?
- Brightness moves every tone up or down together, so the whole picture gets lighter or darker. Contrast pushes light and dark tones apart, which adds punch — or, in the negative direction, flattens the image into a soft, hazy look.
- What does Auto levels do?
- It measures each color channel of your photo, ignores the extreme 0.4% at each end, and stretches what is left across the full range. Washed-out, hazy or underexposed shots usually snap back to life with a single click.
- Can I adjust many photos at once?
- Yes. Drop in as many images as you like — the settings apply to all of them, and you can download the results individually or together as a single ZIP.
- Will adjusting reduce quality?
- The adjustment itself works at full resolution with no downscaling. Only the re-encode matters: choose PNG for a lossless result, or keep JPG/WebP at a high quality setting.
