Frequently asked questions

Is the original file changed?

No. Adjustments apply to a copy; your original file is never modified and nothing is uploaded.

Can I combine grayscale with brightness, contrast and saturation adjustments?

Yes. All four sliders apply together in real time, so you can desaturate a photo while also boosting its contrast and brightness.

Will adjusting these sliders reduce image quality, or just change how it looks?

Only how it looks. Brightness, contrast and saturation are rendered as a color filter and don't resample or compress pixels; quality is set only by the format you choose when downloading.

Is there a quick way to reset to the original image?

Yes, click Reset to set brightness, contrast, saturation and grayscale back to their defaults without reloading the photo.

What file format will the adjusted image download as?

The download keeps your original format when it's JPEG or WebP; any other format saves as PNG.
