Why Use an Image Enhancer?

Poor lighting, camera shake, or low-resolution sensors often result in dull or blurry photos. An image enhancer lets you fix these issues instantly without installing Photoshop. Adjust brightness for dark shots, boost contrast for flat images, increase saturation for vivid colors, and sharpen details — all in your browser. Even small adjustments can make a photo look dramatically more professional for social media, e-commerce, or presentations.

Brightness vs Contrast vs Saturation vs Sharpness

Brightness controls overall lightness — increase to fix dark photos, decrease for overexposed shots. Contrast controls the difference between light and dark areas — higher contrast makes images pop. Saturation controls color intensity — increase for vivid colors, decrease for muted or black-and-white look. Sharpness uses Unsharp Mask to enhance edge definition — great for recovering detail in slightly blurry photos. Start with small adjustments and use Auto Enhance as a starting point.

Frequently Asked Questions

Does the image get uploaded to a server?

No. All processing happens entirely in your browser using Canvas API. Your image never leaves your device.

What formats are supported?

You can upload JPG, PNG, WebP, and most other browser-supported image formats. The output is always PNG.

Can I undo changes?

Click 'Reset' to restore all sliders to their default values and revert to the original image.

What does Auto Enhance do?

Auto Enhance applies a preset combination: Brightness +10%, Contrast +15%, Saturation +20%, Sharpness 30 — a balanced improvement for most photos.

Will the enhanced image be larger in file size?

Possibly. The output is PNG (lossless), so if the original was a compressed JPG, the PNG may be larger. The visual quality will be higher.
