PlatformSize is a static site. The crop, the resize, and the ZIP are done with Canvas and OffscreenCanvas on your device, in a Web Worker when the browser allows it.

What never happens

• The image is not sent to a server. There is no upload endpoint.
• There is no account, and no image is written to our disk because we do not have your disk.
• Analytics scripts are not included. A network trace while you export should show only the files the page itself loaded, as GET requests.

What stays in the tab

The picture lives in memory until you close the tab or remove it. Crop positions (a few numbers: focus and zoom, per preset) can be saved in sessionStorage under a key made from the file name, size, and last-modified time. That record does not contain pixels. Clearing site data for this origin removes it.

EXIF orientation is read locally so a phone photo is not sideways. The metadata is not forwarded anywhere.

What you download

JPG, PNG, and WebP files, or a ZIP of them, are created in the tab and handed to your browser’s download folder. That is the only copy we make.

If you are checking this, open the network panel, drop a photo, and export. You should not see a POST or a PUT, and the image bytes should not appear in any request.
