Are my images uploaded to a server?

No. Compression runs inside your browser using WebAssembly and the File API. The image data never leaves your device.

How much smaller will my file be?

It depends on the image, but most photos shrink by 60-80% with no visible quality loss at typical screen and web sizes.

Is there a file size or batch limit?

No artificial limit is imposed by the tool itself; the practical ceiling is your device's available memory, since compression happens on your machine rather than a server.

Which formats are supported?

JPG, PNG, and WebP are supported as input, and each file is compressed and returned in its original format.
