Convert image to black and white without an upload

This tool turns a color photo into a black and white one right in your browser. Upload one JPG, PNG or WebP, choose a style, and press the button. The preview then follows the sliders as you move them.

Grayscale uses Rec. 709 luma, a standard way to weigh red, green and blue into gray. In our check the result had no colored pixel left. Hold to see the original at any time to compare.

When the preview looks right, download the file. It is rendered again from your full photo, not from the preview.

Because the tool is a plain pixel effect and not AI, it never redraws your picture. Faces, edges and textures stay where they are; only the color is taken out. Green and red tones come out brighter than blue ones, the way the Rec. 709 weighting treats them, so skies often turn darker than the grass under them.

Convert image to black and white privately

Nothing is uploaded

The photo is decoded and converted on your device and never leaves it. There is no account and no sign-up.

Free, with no use limit

This tool is free and has no daily limit or free-image quota, because your own device does the work.

The download is a new file

Your original stays as it is. The download is a black and white copy at the full size of your photo, up to 8000 px on the long side. A JPG gives a JPG, other formats give a PNG. The saved copy has no color left, so keep your original.

Frequently asked questions

No. The photo is processed in your browser and never leaves your device.

Upload a JPG, PNG or WebP, choose Grayscale, High contrast or Pure black and white, and press the button. Adjust Brightness and Contrast while you watch the preview, then download.

Grayscale keeps every gray between black and white, so it still looks like a photo. Pure black and white keeps only two tones, so each pixel is black or white. The Threshold slider decides where that cut falls.

Choose Pure black and white and move the Threshold slider until the lines are solid and the background is clean. Pixels lighter than the threshold become white and darker ones become black.

Raise Contrast, or try the High contrast style. Brightness lifts or lowers the whole picture, which helps when the gray result looks too dark or too washed out.

No. The saved file has no color left, so keep your original photo. To add color to an old black and white picture, the colorize tool on this site makes a guess at it with AI.

The download is rendered from your full photo, up to 8000 px on the long side, not from the small preview. Larger photos are scaled down to that limit. A JPG is saved as a JPG, so it is compressed again.

JPG, PNG and WebP, up to 50 MB, one photo at a time.

Yes. It is free, needs no sign-up and has no daily limit, because it runs on your device.

This page turns the whole photo black and white, with three styles and a threshold. The remove color page can also gray out a single color or keep just one, so use it for a color splash look.

Usually well under a second. In our test on an M-series Mac in Chrome, the preview appeared in about 0.15 seconds and a 4000 x 5333 photo downloaded in about 0.25 seconds. An older device can take longer.

No. It is a pixel effect that runs in your browser, so it does not redraw or invent details. It only removes color and applies your Brightness, Contrast and Threshold settings.

Grayscale weighs red, green and blue differently, as the eye does, with green counting most. Two colors that look equally bright in color can land on different grays. Move Contrast to separate them more.

Yes. Hold the compare button to see the original while you press it. Release it to go back to the black and white preview.
