Adjust image brightness, contrast, and saturation with live sliders and real-time canvas preview. Includes exposure and gamma controls, filter presets (vivid, faded, dramatic, warm, cool), before/after comparison, and bulk batch processing.
Drag and drop one or more images into the upload zone. The live preview canvas updates as you adjust controls. Bulk mode applies the same settings to all images.
Use the Brightness, Contrast, Saturation, Exposure, and Gamma sliders to fine-tune the image. Or click a filter preset — Vivid (punchy colours), Faded (matte film look), Dramatic (high contrast B&W feel), Warm (golden tones), Cool (blue tones), or Reset to original. All adjustments combine and update the preview in real time.
Use the Before/After comparison slider to verify your edits against the original. Download the adjusted image as JPG, PNG, or WebP. In bulk mode, all processed images are packaged into a ZIP download.
Brightness adds or subtracts a fixed value from every pixel uniformly — it lifts or lowers the entire tone range linearly, which can clip highlights or crush shadows if pushed too far. Exposure simulates camera exposure adjustment and is gentler on highlights. Gamma adjusts the midtone curve — increasing gamma brightens midtones without blowing out highlights (this is how monitor calibration works). For natural photo enhancement, Gamma and Exposure are usually preferable to raw Brightness.
Contrast stretches or compresses the tonal range around the midpoint (128 in 0–255 scale). Increasing contrast pushes darks darker and lights lighter, separating tones and making the image feel more vivid and defined. Decreasing contrast brings all tones closer to the midpoint, creating a flat, faded, or matte look popular in film-emulation styles.
Saturation controls the intensity of colours. At 0, colours are unchanged. Increasing saturation makes colours more vivid and punchy. Decreasing saturation moves colours toward gray. At minimum, the image becomes fully desaturated (grayscale). This is applied using a luminance-preserving formula so bright and dark areas are not accidentally clipped when saturation is boosted.
Each preset is a combination of the five adjustment sliders tuned for a particular look. Vivid boosts contrast and saturation. Faded reduces contrast and slightly lifts blacks for a matte film look. Dramatic pushes contrast strongly and desaturates slightly. Warm adds brightness to red and slightly desaturates blue. Cool does the reverse. All presets are applied non-destructively and can be further fine-tuned with the sliders after selecting.
When downloaded as PNG, there is no quality loss — PNG is lossless. JPEG download applies standard compression (92% quality) which introduces minimal artifacts. The adjustments are applied directly to pixel values in the Canvas API, so there is no double-compression from intermediate processing. For maximum quality preservation when making significant adjustments, download as PNG.
Yes — bulk mode applies the same slider settings and preset to all uploaded images. All processed images download as a ZIP archive. This is useful for colour-correcting a batch of product photos, warming up an entire vacation album, or applying a consistent filter to a social media image set.
