Image Adjustor

Most quick photo edits don't need a single, dramatic fix — they need small nudges to two or three things at once: a bit more brightness, slightly punchier contrast, maybe a touch more saturation, all applied together so you can see how they interact rather than guessing at each one in isolation and re-uploading between steps. This combines Forge's five individual adjustment tools — Brightness, Contrast, Saturation, Hue, and Sharpness — onto one photo with one set of sliders, so the live preview always reflects everything at once.

The adjustments are applied in a fixed, sensible order: brightness, contrast, saturation, and hue are composited together as a single fast canvas filter operation, and sharpness — which needs real per-pixel math rather than a built-in browser filter — runs as a second pass on top of that result. That means dragging any of the first four sliders stays instant even on larger photos, while the sharpness slider (if you're using it) does slightly more work behind the scenes. Reset puts every slider back to its default in one click if you want to start over, and nothing commits until you actually download.

As with every tool here, this runs entirely client-side: the photo is decoded, adjusted, and re-encoded in your browser using the Canvas API, and it's never uploaded to a server at any point. If you only need one specific adjustment rather than all five, the individual tools linked above are lighter-weight versions of exactly the same underlying engine, each focused on a single slider.
