About Image Opacity Adjust.

Image Opacity Adjust

Adjust image transparency and export PNG or WebP with alpha preserved. Processing runs on your device. Your source image is not replaced.

Preview and export

The preview uses a smaller copy for responsive adjustments. Download renders the effect again at the original dimensions, including the selected size changes. PNG and WebP support transparent areas; JPG uses your selected background color. Animated inputs are treated as a still image.

What the tool does

Opacity changes the alpha channel. Choose PNG or WebP to keep transparency; JPG always needs a solid background.

Local limits

Images up to 50 MB and 40 megapixels are supported. Expanded output is limited to 40 megapixels and 16,384 pixels per side to stay within browser canvas limits.
