No tools match your search.
Where your photos go
Nowhere. The page reads each file from your disk and processes it with the image tools built into your browser. There is no upload step, so there is nothing for us to keep. You can check this yourself: open the Network tab in your browser’s developer tools while a batch runs, and none of your images appear in it.
HEIC is the exception, because browsers can’t decode it on their own. The first time you convert one, the page downloads a 2 MB decoder (libheif), and your browser keeps it for next time.
For PDF files there is ShyPDF, built the same way.
