0% is completely transparent, 100% is fully visible/opaque.
Does this support all image types?

Can I adjust opacity of specific areas?

How to adjust image opacity
Upload an image and use the opacity control to make the image more or less transparent. The browser draws the source image onto a canvas using the selected alpha level and prepares the processed result for download.
Browser-based processing
The image effect is produced with browser image and Canvas processing. The preview lets you inspect the result before using the available download action.
What the effect changes
Lower opacity makes the entire rendered image more transparent; it does not selectively remove the background.
Tips for better results
Start with a clear source image and compare the preview with the original before downloading. Stronger effect settings can intentionally remove or alter visible detail, so choose the setting according to the result you need.
