What the percentage means
100% keeps the original transparency. 50% halves each pixel's opacity. 0% makes the image invisible.

When to reduce image opacity
Lower opacity when an image needs to support other content instead of competing with it.
Watermark assets
Lower the opacity of a logo or signature, download it as a transparent PNG, then place it over your photo or document in your preferred editor.
Start around 25–50%Web overlays
Create a semi-transparent PNG for a hero overlay, badge, UI layer, or decorative element that needs to blend with different backgrounds.
Check light and dark backgroundsPresentation backgrounds
Fade an illustration, texture, or logo behind slide text while preserving the original image dimensions for your layout.
Keep important text readableDesign mockups
Try a softer artwork layer in a landing page, product mockup, or social graphic before exporting a clean transparent PNG.
Use 75% for a light fadeHow to change image opacity online
There is no need to open a full design editor for a simple transparency adjustment.
Upload an image
Choose or drop a PNG, JPG, JPEG, or WebP. The image opens at its original pixel dimensions.

Copy or download
Copy the current PNG directly to your clipboard or download it with its adjusted transparency.
Choose the right operation
Opacity vs. removing a background
Changing opacity fades every pixel by the same percentage. Use it to soften a watermark or design layer.
Removing a background makes only selected pixels transparent. Use background removal to isolate a subject or remove a white, black, or green backdrop.

Why your PNG looks different on different backgrounds
A light background can soften a dark logo; a dark background can help reveal pale artwork and faint edges. Check both to see how your PNG will look in its final layout.
Frequently asked questions
Quick answers about output, supported formats, and copying.
How do I lower the opacity of an image?
Upload an image, set a percentage, then copy or download the PNG.
Does changing opacity change the RGB colors?
No. Only transparency changes; the original RGB values stay the same.
Will an already transparent PNG become opaque?
No. Fully transparent areas stay transparent at every setting.
Why does the same image look different on a white or black background?
Transparent pixels blend with the background behind them. Switch between white, black, and checkerboard to inspect the result; the preview background is not exported.
Can I make a JPG transparent with this tool?
Yes. Lower its opacity and export as PNG; JPG cannot store transparency.
Can I restore the original opacity after several changes?
Yes. Choose 100% or Reset. Each adjustment starts from the original image.
Can I copy the transparent image directly?
Yes, if your browser supports image copying. If access is blocked, download the PNG instead.
Can I edit animated images?
Animation is not preserved. Animated PNG or WebP exports as a single still PNG.
Is this image opacity editor private and free?
Yes. Free, no signup, and all image processing stays in your browser.
