Guide & FAQ

Good to know

Are my images uploaded?

No. The image stays on your device while it is made smaller. OnDeviceKit never receives the file.

Which image types can I use?

You can open JPG, PNG, and WebP files up to 30 MB. You can keep the same file type or save the result as JPG, PNG, or WebP.

Why can the result be larger?

Changing the file type or choosing high image quality can create a larger file. The result always shows the real size change before you download.
