Adjust Image — Brightness, Contrast, Saturation & Warmth
Adjust image brightness, contrast, saturation and color temperature (warm / cool) with live sliders: fix dark or flat photos and make colors pop. Works on desktop, tablet & mobile — batch, local, no upload.
Adjusting an image means fine-tuning a few basic parameters: brightness for light/dark, contrast for depth, saturation for color intensity, and temperature for warm/cool tone. Common for rescuing dark or washed-out photos and making food or product shots pop. This tool previews changes live with sliders and bakes them into the pixels only on export, with batch support. Processing runs entirely in your browser — no upload.

Adjustments FAQ
No. The slider preview uses CSS and export uses the browser Canvas — fully local, your images never leave your device.
It is an approximation using hue rotation / sepia to mimic warm and cool, good for quick toning — not color-science white balance.
Yes — upload a batch, apply the same settings to all, then download as a single ZIP.
Export re-encodes, so JPG has a slight loss; over-brightening or over-saturating also clips highlight detail, so keep it moderate.
