Overview

Save Image As Type is a browser extension that converts web images to different formats (JPG, PNG, WebP, AVIF) directly in your browser. We are committed to protecting your privacy. This policy explains what data we do and do not collect.

Data we do NOT collect

Images: We never collect, store, upload, or transmit any images you convert. All image conversion happens 100% locally in your browser using the Canvas API.
Full URLs: We never transmit the full URL of an image you convert, or of the page you're on, to us or anyone else. If you turn on the optional local save history described below, it stores full image URLs - but only on your device, never anywhere else. (The one exception, a bare hostname rather than a URL, is described under "Data we DO collect" below.)
Browsing history: We have no access to your browser history.
Personal information: We do not collect names, email addresses, or any personally identifiable information (PII).
Extension cookies: The extension itself does not use cookies. (This website uses Google Analytics cookies — see below.)

Stored only on your device

Local save history. This is off by default - a fresh install of the extension keeps no record of what you save. If you turn it on in Settings, the extension adds one entry per save to a log kept only on your device: the image's full URL (so you can find and re-download it later), the output format, the file size, the time, and a reference to your browser's own download record (so the saved file can be revealed in your file manager). This log is never transmitted anywhere and never synced. You can clear it at any time, and turning the setting off erases whatever is already stored.

Data we DO collect

Anonymous usage analytics. To understand which features are used and to find and fix bugs, the extension and this website send anonymous event data to Google Analytics (GA4). Every event carries only a random, anonymous identifier plus your browser and the extension version - never your identity. On a normal conversion, that event records which output format was chosen and whether it succeeded.

When a conversion fails, the event includes a bit more, so we can find and fix the sites that break it. This is the complete list of what's added:

image_host - the bare hostname of the image, for example cdn.example.com. Never the path, query string, or fragment, and never sent at all for data: or blob: images.
error_message - a diagnostic message, cut to 100 characters, with any URL inside it replaced by its bare hostname (and any file:// path replaced with the literal text file:[redacted]).
error_name, http_status, and source_format - the kind of error, the HTTP status code if there was one, and the original image's format.

We never send your images, the full URL of an image or the page you're on, page contents, or your browsing history. Image conversion always happens 100% locally in your browser.

Opt out anytime: in the extension, open Settings → Privacy and turn off "Send anonymous usage analytics." All telemetry stops immediately. The Firefox build ships with no analytics code at all - there is nothing to opt out of.

Permissions

The extension requests the following browser permissions:

contextMenus: To add the right-click menu items
downloads: To save converted images to your device
activeTab: To access image data on the current page
storage: To save your format and quality preferences, and the optional local save history if you turn it on (all locally, never synced externally)
offscreen: To create a hidden canvas for image conversion
Host permissions: To fetch images from any website for conversion (images are never sent anywhere)

Third-party services

Google Analytics (GA4), operated by Google LLC, processes the anonymous usage analytics described above. See Google's Privacy Policy. No other third party receives any data from the extension, and your images never leave your device.

Changes to this policy

If we make changes to this privacy policy, we will update the "Last updated" date at the top of this page. Significant changes will be noted in the extension's changelog.
