What happens to your images
Nothing leaves your device. The converters use the Canvas API built into your browser and, for HEIC files, a WebAssembly decoder that is downloaded to your browser and runs there. Your image is read from your disk, converted in memory and written back to your disk as a download.
Because there is no upload step, there is no copy of your file on any server, no queue, and no retention window to worry about. Closing the tab ends the process entirely.
What we do collect
Standard web server and analytics data: pages viewed, referring site, approximate region, browser and device type, and whether a conversion was started or completed. This is aggregate usage information used to decide which converters to build next.
We do not sell data, and we do not use your images to train anything — we could not, since we never receive them.
Third parties
Fonts are self-hosted from this domain, so loading a page makes no request to a font CDN. The HEIC decoder is served from this domain as well. There are no advertising networks, tracking pixels or social embeds on the site.
What is stored on your device
One value in localStorage records your light or dark theme preference. That is the only thing this site writes to your browser, and clearing your site data removes it.
