01What ImageConv Does
ImageConv is a browser extension that converts images between PNG, JPG, WEBP, and AVIF formats. All conversion is performed locally in your browser using the Canvas API.
All conversion happens inside your browser and your converted files are never uploaded. The extension contacts the network in two cases only: it fetches the original image from the site you right-clicked (or from the page's own image URLs during batch export), and it validates an optional Premium licence. Those image requests go straight to the source website, which may see your IP address and request metadata. No analytics, no account.

ImageConv does not collect any personal data, including but not limited to:
ImageConv does not upload image data or browsing data to us. It fetches the source image directly from the website you act on, and contacts api.annmax1983.com only for optional Premium licence checks. If you never activate a licence, the licence server is never contacted. Source websites may log the image request as they would any normal page request.
ImageConv stores the following data locally on your device using chrome.storage.local:
Local data stays on your device except for the optional licence fields described under Third-Party Services; uninstalling deletes the local copy.
ImageConv requests the minimum permissions necessary:
Host permission <all_urls> is required to fetch images from any website when you right-click to convert, and to read the images already loaded on a page when you use batch export. Apart from that, ImageConv does not access page content.
License Verification (Premium Features): If you activate a premium license, ImageConv contacts our license server (api.annmax1983.com) directly; Creem only handles the payment. The request includes: license key, a random install identifier, plugin identifier, and browser metadata (version, language, timezone). ImageConv does not connect to any other third-party servers, analytics, or tracking services. Our license server records the IP address of these requests solely for rate limiting and abuse prevention — never for profiling, advertising, or sharing with third parties.
ImageConv does not knowingly collect any data from children or any other users.
Your settings and content stay in your browser until you delete them in the extension or uninstall it. Uninstalling removes the extension's local data. Nothing is retained on our servers, because your content is never sent to them.
If this policy changes, the revised version will be published on this page with a new date. Material changes will be noted in the extension's release notes.
