Frequently asked questions

Are my files uploaded to a server?

No. Everything is processed inside your browser, and your files never leave your device.

Does the border change the image size?

If you choose “add frame around,” yes: the image grows by the thickness of the border.

Do rounded corners have a background?

They're transparent if you save as PNG or WebP.

About this tool

A white frame works well for product photos, or to make an image stand out on a dark background.

With rounded corners, the image is saved as a PNG with transparent corners.
