Adjust Image
The sliders change the preview immediately. The download uses the full photo, up to 16 megapixels. Hold "Show original" to compare.

Open a photo. The histogram updates with the preview.
Lift a dark photo, cool a warm one, or pull color out of a scan. Adjustments run in this tab. The histogram is the brightness of the preview, not a camera light meter.
What the sliders change
The preview box stays a fixed height so the sliders and the picture can share the screen. Drag a slider and look at the box above it. The download is not that small picture. It is the full photo, up to 16 megapixels. Hold Show original when you want the untouched preview back for a moment.
Exposure multiplies the light, so shadows and highlights move together. Brightness adds a flatter lift and is easier to blow out. Highlights and shadows let you lean on one end. Temperature and tint are color shifts, not white balance from a raw file. Vibrance is the safer color control on faces. Saturation pushes every color, including skin. Sharpness is a mild unsharp mask. It cannot invent detail that the lens missed. Vignette only darkens the corners.
These are looks, not recovery. A sky that is already pure white stays white. A missed focus stays soft. Invert is a graphic look, not a color-negative scan. If the photo also has a location tag you do not want to publish, run EXIF Viewer on the download afterward. Adjusting pixels does not remove metadata by itself.
How to use
- Open the photo. Presets set the sliders. Original puts every slider back to zero.
- Exposure multiplies the light. Brightness adds a flatter lift. Contrast expands the distance from middle gray.
- Highlights and shadows lean on the bright or dark parts. Temperature shifts toward amber or blue. Tint shifts green or magenta. Vibrance boosts weak color more than color that is already strong.
- Sharpness is a mild unsharp mask, not a detail-recovery AI. Vignette darkens the corners. Hold Show original to compare. Download uses the full photo.
Limits
These are pixel math, not a raw developer. They cannot recover a blown-out sky or a missed focus. Invert is a look, not a film negative with an orange mask. JPG output is compressed at the quality you set. For a smaller file after that, use Image Compressor. To cover a face before you publish, use Blur and Mosaic. Photos over 16 megapixels are scaled before the sliders run.
Questions
Why does the preview look softer than the download?
The preview is about 1,100 pixels on the long side so the sliders stay quick. The file you download is the full photo, up to the 16 megapixel cap.
Saturation versus vibrance?
Saturation pushes every color, including skin. Vibrance mostly lifts colors that are still gray, and leaves strong colors alone.
Why is the on-screen photo smaller than my file?
The box is capped so the sliders stay on the same screen. The file you download is the full photo, up to the 16 megapixel limit. The histogram is measured from the preview.
Does adjusting remove the location?
No. Pixel changes do not delete EXIF. If the photo has GPS and you plan to publish it, open the download in EXIF Viewer and save a copy without metadata.
Is the photo uploaded?
No.
