Frequently Asked Questions
Is the Chrome extension free?
Yes, the extension is completely free and open-source. There are no usage limits — every image you download from supported platforms is processed automatically.
Will it be on the Chrome Web Store?
We're working on it. In the meantime, you can install it manually by downloading the .zip and loading it in Developer Mode. It takes less than 30 seconds.
Does the extension send my images anywhere?
No. All image processing happens entirely in your browser using local JavaScript. The extension makes zero network requests — your images never leave your device.
What's the difference between the extension and the online tool?
The extension works automatically in the background — when you download an image from a supported site, it's cleaned before saving. The online tool lets you upload any image manually and supports more platforms like Grok.
Does it work on Edge, Brave, or Arc?
Yes. Any Chromium-based browser supports Chrome extensions. Just follow the same installation steps.
