Save Image As Type asks for only what it needs to convert and save images locally. Nothing here is used for tracking, advertising, or sending your data anywhere. All image conversion happens 100% on your device using the browser's Canvas API. Below is every permission and the precise reason it is requested.

Permissions

contextMenus

Adds the right-click menu items ("Save image as JPG/PNG/WebP/AVIF" and the copy option). This is how you trigger a conversion — without it the extension would have no entry point.

downloads

Saves the converted image file to your device. The download is the final output of a conversion you explicitly requested; the extension never downloads anything on its own.

activeTab

Grants temporary access to the page you are actively using, only when you invoke the extension, so it can read the image you right-clicked. Access is scoped to that interaction and ends when you navigate away.

scripting

Injects the small content script that locates the target image (including CSS background images) and, on Firefox, performs the canvas conversion in the page context. It runs only to fulfil a conversion you started.

storage

Saves your preferences — default format, per-format quality, and whether the copy menu is shown. These settings live in your browser's storage and are never sent to us or any third party.

offscreen (Chrome / Edge only)

Creates a hidden document with a canvas so the extension can convert images from the service worker, which has no DOM of its own. It renders nothing visible and exists only for the duration of a conversion. Firefox does not expose this API, so the Firefox build does not request it.

notifications

Shows a brief notification when a conversion or download fails, so you know what happened instead of the action silently doing nothing. Notifications are local and contain no personal data.

clipboardWrite (Chrome / Edge only)

Lets the "Copy image as PNG" menu item place the converted image on your clipboard. It is used only when you pick that menu item. Firefox handles clipboard writes without this permission, so the Firefox build omits it.

Host permissions (<all_urls>)

Allows the extension to fetch the bytes of the image you chose, on whatever site it lives on, so it can be converted. Fetching happens in the background to bypass the page's CORS restrictions, and the image data is used only for the local conversion — it is never uploaded or sent anywhere. Broad host access is required because images can appear on any website.

Data collection

None of these permissions are used to collect your images, image URLs, browsing history, or any personal information. For the full picture of what we do and do not collect, see the Privacy Policy.
