Your images stay yours.
FormatSprout converts images entirely inside your web browser. Image files, filenames, and image contents are not uploaded to or stored on our servers.
Analytics
We use Umami Cloud for cookieless, aggregate analytics. It records page visits and limited product events such as input and output formats, counts of selected files, conversion starts, successful conversions, processing duration, failure category, and download type. We also collect browser performance measurements and campaign parameters from links. We never send filenames, image contents, dimensions, or embedded metadata.
Exclude your visits
You can exclude your visits and conversion events in this browser.
The preference stays on this device. Reload after changing it. Repeat in each browser you use for testing.
Local processing
Temporary previews and converted files exist only in your browser’s memory. FormatSprout attempts to release them when you remove a file, replace a result, or leave the page. Your browser controls final memory cleanup and downloaded-file storage.
Third parties
Hosting is provided by Vercel and aggregate analytics by Umami Cloud. We do not sell personal data or use uploaded-image storage because image conversion does not involve an upload.
