Questions about black and white image
Which formats work?
JPG, PNG and WebP. You get the same format back.
Is my photo uploaded?
No. It is converted in your browser.
Can I undo it?
Keep your original; the download is a new black-and-white copy.
What the conversion does
The tool removes the colour from your picture and keeps the light and dark values, so the result is made of shades of grey. It uses your browser’s grayscale filter, and the size of the picture does not change. The file is saved in the same format as the original with -bw added to its name: a JPG stays a JPG, a PNG stays a PNG and a WebP stays a WebP.
| Your picture | You get | See-through areas |
|---|---|---|
| JPG | A grey JPG named like photo-bw.jpg | JPG has no transparency, so they become white |
| PNG | A grey PNG named like logo-bw.png | Kept as transparent |
| WebP | A grey WebP named like image-bw.webp | Kept as transparent |
When black and white works well
Black and white suits portraits, street scenes and pictures with strong light and shadow. Because colour is removed, two colours of similar brightness, such as a red and a green, can turn into almost the same grey and lose their separation. If the result looks flat, the original probably relied on colour contrast rather than brightness.
It is also handy for printing documents and photos when you want to save coloured ink. The tool changes only the colours. Cropping, resizing and other edits are done with the other image tools, and your original file is never changed.
