Adjusting image opacity
What opacity does
Opacity controls how see-through the whole image is. At 100% it's fully solid; lower it and the image fades, letting whatever is behind it show through. The result is saved as a PNG, the only common format that stores partial transparency.
This is perfect for watermark-style overlays, faded backgrounds behind text, or ghosted images in a design.
Not the same as removing a background
This fades the entire image uniformly. To make only the background transparent (keeping the subject solid), you'd need background removal — a different operation.
Frequently asked questions
What format do I get?
A PNG, which preserves the partial transparency. JPG can't store transparency.
Does it make the background transparent?
No — it fades the whole image evenly. It doesn't isolate or remove a background.
Will the dimensions change?
No, the output keeps the original size.
Is my image uploaded?
No. The opacity is applied locally in your browser.
