About This Tool

This tool focuses on adjusting image brightness via a darkening operation. It processes RGB pixels, preserves alpha channels, and maintains overall color relationships.
Conceptually, each pixel's luminance is scaled by a factor derived from an intensity input. If color_preserve is enabled, the relative hue and saturation relationships are maintained while brightness drops.
Applications include preparing assets for overlays, creating shadows for UI designs, or simulating low-light scenes for photography workflows.
Core features include input file or URL, darkness intensity (0-100%), optional gamma correction, and export as PNG or JPEG. Outputs include dimensions, color depth, and file size estimates.
The service is designed for designers, developers, and content teams who require fast previews, repeatable edits, and shareable results without installing software.

Frequently Asked Questions

Find Quick Answers

What input formats are supported?

Supports PNG and JPEG inputs via file upload or URL. If an unsupported format is provided, the tool returns a non-destructive error and does not modify the input. Local validation reduces the risk of partial conversions.

Can I preserve colors when darkening?

Yes. When color_preserve is enabled, hue and saturation remain consistent while brightness decreases. Gamma adjustments offer perceptual control over darkness to prevent washout or clipping.

How is darkness calculated?

The tool scales each color channel by a factor derived from intensity (0-100%). If gamma correction is applied, channels are adjusted to preserve perceptual brightness and color relationships.

What outputs can I export?

Exports are provided as PNG or JPEG with the same dimensions as the input. Metadata includes width, height, color depth, and estimated file size to support asset pipelines.
