About this tool
Load a photo and adjust brightness, contrast, saturation, warmth and sharpness with live sliders, or press Auto enhance for a quick histogram-based levels correction plus a light colour and sharpness lift. Everything is recalculated from the original pixels each time, so you can go back and forth freely, and the photo never leaves your browser. Download the finished image as a PNG.
How to use it
- 1 Choose a photo to open it in the editor.
- 2 Drag the sliders, or press Auto enhance for a fast starting point.
- 3 Press Download to save the result as a PNG.
Frequently asked questions
What does Auto enhance do?
It stretches the tonal range using the image histogram (so blacks and whites reach the ends of the scale) and adds a small contrast, saturation and sharpness boost. You can fine-tune every slider afterwards.
Is the photo uploaded?
No. It is decoded and processed entirely in your browser with the Canvas API. Nothing is sent anywhere.
Why is a very large photo resized?
The editor caps the working image at about 1600 px on the long side so the live sliders stay responsive. Export is at that working size.
