Frequently Asked Questions

Common questions about the free online image opacity tool.

Choose your image and drag the opacity slider. The checkerboard behind the preview shows exactly which parts become see-through.
No. Every pixel is adjusted on a canvas inside your browser, so your picture never leaves your own device.
The alpha channel of each pixel is multiplied by the slider value, so 0 percent is fully invisible and 100 percent is fully opaque.
The checkerboard is only a preview backdrop. The downloaded PNG keeps real transparency, so it drops straight onto any background.
Yes. Use the opacity tool on a logo or sticker to make it blend into a busy background without extra editing software.

The source image size is used as it is, and the working size is shown in the panel so you always know what you are exporting.
