Adjust colors, filters and sharpness

How to adjust an image

1. Choose one or more static JPEG, PNG, WebP, AVIF or uncompressed BMP images, a folder or a ZIP archive.
2. Choose a preset or adjust the sliders. Compare the effect with the original.
3. Select an output format, apply the adjustments and download the result.

Color controls and useful presets

Start with vivid, soft, monochrome or sepia, then adjust exposure, brightness, contrast, saturation and warmth. Each slider shows its value and supports keyboard input. Restore adjustments to return to the original settings.

Exposure scales decoded RGB values, contrast works around mid-gray, and saturation uses luminance. These are edits to ordinary JPEG, PNG and WebP pixels, rather than a RAW photo development pipeline.

Sharpness and transparent images

Sharpness adds edge contrast without changing dimensions or alpha. Invisible neighboring pixels are excluded from its color contribution so transparent edges do not pick up hidden colors.

The live preview is reduced for responsiveness. Fine edges can look different at full size; inspect the actual processed result. PNG avoids lossy encoding; JPEG and WebP also offer a quality setting.

Process a folder or ZIP locally

Import up to 50 images, 100 MB of input and 100 million pixels in total. Each image must stay within 15 MB, 16 million pixels and 8192 pixels per side. Folder imports include nested folders; non-image files are skipped. All files stay in this page’s memory.

Apply the same settings and process images one at a time. Failed images are listed separately and do not block other files. Preview individual results or download a ZIP with preserved folder paths and unique output names. Encrypted ZIPs, ZIP64 and nested archives are unsupported. Changing settings clears old results; cancelling keeps already completed results.
