About Image Enhance

Image Enhance tweaks brightness, contrast, saturation, sharpness, blur, hue, and 10 other parameters of an image, in real time, via CSS filters and a small convolution kernel — fully client-side. Drop an image, drag the sliders, see the before/after live, then download the enhanced PNG. Use it to brighten a dark phone photo before sharing, boost saturation on a faded scan, sharpen a slightly blurry product shot, or apply a vintage colour grade for a blog hero. Sixteen sliders cover the common adjustments without the complexity of Lightroom or GIMP.

Frequently Asked Questions

What adjustments are available?

The tool offers 16 adjustments in 4 categories: Light (exposure, brightness, contrast, highlights, shadows), Color (saturation, vibrance, temperature, tint, hue), Detail (sharpness, blur), and Effects (vignette, grain, grayscale, sepia).

Are my images uploaded to a server?

No, all processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device.

Can I compare with the original?

Yes, hold the compare button at the bottom of the preview to temporarily see the original image. Release to see the enhanced version.

Why are my changes not visible until I scroll the slider?

The preview updates on slider release rather than on every input event to keep the UI smooth on phones, where re-running 16 CSS filters per pixel-change would lag. Drag, release, see the result. Hold-and-drag still works for fine tuning — just the final state is what's rendered.

Are the changes destructive?

Only the downloaded PNG is destructive. The source image stays untouched in your browser session — you can reset all sliders to zero or close the tab without affecting your original file. The download bakes the current slider state into a new PNG file.
