About this tool
Open a photo and pick a look (auto, vivid, warm, cool, black and white, vintage or brighter), each previewed on your own photo, or fine-tune brightness, contrast, saturation, warmth and sharpness with sliders. A before/after slider shows the difference. Every change is recalculated from the original pixels, so you can go back and forth freely; the preview is scaled down to stay fast, and the download is made from the original resolution (up to 4096 px). The enhancer is the Adjust step of a free photo editor, so you can also crop, rotate, remove the background and choose the size and the format (JPG, PNG or WebP). The photo never leaves your browser.
How to use it
- 1 Choose, drop or paste a photo.
- 2 In Adjust, pick a look or move the sliders, and drag the before/after slider to compare.
- 3 If you want, crop or rotate it in Crop & rotate and choose the size and format in Size & format.
- 4 Click Download to save it in full resolution.
Frequently asked questions
What does Auto 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.
Does it lower the resolution?
Only on screen. The preview is scaled down so the sliders respond instantly, but the download is made from the original photo, up to 4096 px on the longest side (larger photos are scaled to that size).
Can I save it as JPG, PNG or WebP?
Yes. In Size & format choose JPG (the default for photos), PNG (lossless) or WebP, and a quality or a target size in KB.
