What this contrast tool does
The Image Contrast Adjuster lets you increase or reduce contrast in JPG, PNG, and WebP files directly in your browser. It is useful when images look flat and low-impact, or when highlights and shadows feel too strong and need to be softened.
You can test preset values or set an exact contrast percentage with the slider. After the contrast correction, you can continue with the Image Brightness Adjuster for exposure changes or the Image Resizer & Compressor to optimize the final file.
Everything happens locally in your browser, which keeps the tool private and fast. No server upload is needed to preview, increase contrast, reduce contrast, or export the result.
How it works
1. Upload or drag in a JPG, PNG, or WebP image.
2. Move the contrast slider below 100% to soften contrast or above 100% to increase light-dark separation.
3. Preview the adjusted result instantly and choose JPG, PNG, or WebP export.
4. Download the final file or continue with brightness, crop, rotate, resize, and compression tools.
Examples and common use cases
Use the tool for quick tonal corrections before sharing, resizing, compressing, or converting your image.
Make screenshots easier to read
Boost contrast on UI captures, dashboards, and tutorial screenshots so text and controls stand out more clearly on different screens.
Soften harsh graphics
Reduce contrast on over-processed photos or bold graphics when highlights and shadows feel too aggressive for your layout.
FAQ
Does this contrast tool upload my image?
No. Contrast adjustments happen locally in your browser, so your image stays on your device while you preview and export the result.
Can I increase and reduce contrast for JPG, PNG, and WebP files?
Yes. You can move the contrast slider below 100% to soften contrast or above 100% to increase the difference between dark and light areas, then export as JPG, PNG, or WebP.
Will contrast adjustment change image dimensions?
No. Contrast changes only affect how light and dark tones are rendered. The width and height remain the same as the original image.
What happens to transparent PNG or WebP files if I export as JPG?
JPG does not support transparency, so transparent areas are flattened onto a white background during export.
