Most free PDF sites upload the file and ask you to trust a deletion policy. imissfiles runs in the tab. There is no upload endpoint. Open DevTools → Network, drop a file in, and you can watch that nothing the size of your document leaves. Good at: extract the original JPEGs out of a PDF (not a page screenshot), photo of a table → Excel, merge/compress/unlock, HEIC → JPG, scan to PDF. Not Acrobat. Not layout-perfect PDF-to-Word. No account.

The claim is checkable. Open the extract page, open DevTools → Network, drop a PDF in. If you see a POST the size of the file, I failed.

Most “extract images” tools screenshot the page. This one pulls the original JPEG/PNG bytes out of the file. If yours comes back as a screenshot instead, tell me what the PDF looked like.
