FAQ

Good to know.

How do I convert an image to black and white?
To convert an image to black and white, open the Pixasur Grayscale Image tool, add your photo, and set the grayscale slider to full, then download it. The conversion runs in your browser and uses true luminance weighting so the tones stay accurate.
Is the grayscale converter free?
Yes, the Pixasur Grayscale Image tool is completely free with no sign-up and no watermark. You can convert as many photos to black and white as you want, and each one is processed on your device.
Does the black and white converter upload my photo?
No, the Grayscale Image tool runs entirely in your browser, so your photo stays on your device and is never uploaded. The black and white conversion happens client-side with the Canvas API.
Can I make a photo partially grayscale?
Yes, the Grayscale Image tool uses an amount slider, so you can go from a subtle desaturation to a full black and white. This lets you keep a hint of color or remove it completely before you export.
What formats does the grayscale tool export?
The Grayscale Image tool exports the black and white result to JPEG, PNG, or WebP, with no file size limit on the photo you load. PNG and WebP lossless keep every pixel of the converted image.
