How to use Adjust Image
1. Select your input
Choose a JPG, PNG or WebP image from your device using the file button or supported drop area. The standard file picker accepts browser-readable images up to 25 MB; decoding support depends on the file and browser.
2. Understand the settings
Each slider changes a different visual property; small adjustments are easier to judge than extreme ones.
3. Process and review
Correct exposure first, then contrast and colour, and add limited sharpness last. Process and compare with the original.
4. Save your result
Use the result’s Download control after processing. Keep your original separately and inspect the exported copy at its intended display size; the preview alone is not the file you will share.
Supported formats
Input: browser-readable images, normally JPG, PNG and WebP, up to 25 MB. Output controls include the shown Keep, JPG, PNG or WebP choices. Keep preserves a supported source encoding choice, not byte-for-byte original data; animation is not preserved.
When to use this tool
Make deliberate brightness, contrast, saturation and sharpness changes using the editing controls. Work from the original rather than repeatedly resaving a lossy copy.
What to check in the result
Check bright highlights and dark shadows for clipping. Strong saturation or sharpness can introduce unnatural colours or outlines.
Continue with Enhance Image when that step fits your workflow.
A practical example
Lift a dark indoor photograph while watching whether pale skin and window highlights become clipped.
Capabilities and limitations
Sharpness cannot restore missing detail. Large changes can create halos, clipped highlights or unnatural colours.
Troubleshooting
If highlights clip or shadows become solid, reduce contrast or brightness. If halos appear, reduce sharpness and compare at full size.
Processing and privacy
Image pixels are processed on your device. Loading the website and processing assets still uses a network connection, and hosting may receive normal request information. Keep original files backed up.
Questions about Adjust Image
Which control should I change first?
Start with brightness and contrast, then adjust saturation and sharpness one at a time.
Can adjustment recover clipped detail?
No. Detail that was not captured in the source cannot be reliably restored by tone controls.
