Your files never leave your device.
Shrink photos, merge PDFs, cut out backgrounds and turn voice memos into text. It all happens in this browser tab, so there is nothing to upload and nothing to send.

Your files never go back
No request carries them. Your browser's Content-Security-Policy also blocks connections to any other server.connect-src 'self'
Don't trust us. Check.
Saying "we don't upload your files" is easy. These four checks take a few minutes and need nothing but your browser.
connect-src 'self'enforced by your browser
Counted live from your browser's own record of the requests this page has made since it opened. Browser extensions can add requests of their own, and those show up here too. The count only watches; the policy above is what stops anything else.
Watch the network
Open your browser's developer tools, select the Network tab and process a file. No request carries your file anywhere.
Read the security policy
Every page is sent with a Content-Security-Policy header that only allows network connections back to eolietech.com. Your browser enforces it, not us.
Go offline
Load a tool, disconnect from the internet and process another file. It still works, because the work never needed a server.
Read the code
The code is open source under AGPL-3.0, so anyone can audit exactly what each tool does.
Made by one developer in the Aeolian Islands
Eolietech is built and looked after by candygoogy, a developer from the Isole Eolie, the volcanic islands off the north coast of Sicily. Postcards leave the islands every day. Your files stay where they are.
Pro comes later
Some jobs are too heavy for a browser. Pro will add server and AI features and an API, as an optional paid plan. The free tools stay free.
