Scale RGB channels by 2 raised to an exposure-stop offset. Use this for a focused raster editing step. Keep your source image and inspect the exported PNG; the tool does not modify the original file.

How to use it

Choose a browser-supported raster image. A reproducible sample PNG is linked below. Set exposure stops. Choose Create PNG. Review the output, then copy or download it. PNG export contains the rendered image and does not copy original metadata.

Reproducible PNG workflow

Settings: Exposure stops: 0.5

Input:

200×120 PNG, RGB(100,150,200), with a transparent 10×10 upper-left corner.

The result is a downloadable PNG. Verify its appearance and transparency in an image viewer.

Output:

PNG image ready · 200 × 120 pixels

The example produces a raster-image result. Inspect the preview and exported dimensions; filters can change appearance while keeping the original pixel count.

Limitations and common mistakes

Uses the decoded first raster frame and exports PNG. Animation, original metadata and exact color-profile behavior are not preserved. Use an original copy and inspect the result.
Image limits: 12 MB and 12 megapixels. Only a decoded raster frame is used; animation, original metadata and exact color-profile handling are not retained.
