How it works
- Enter the title, description, URL and image URL.
- Check the card preview.
- Copy the tags into the <head> section of your page’s HTML.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
My image is not showing in the preview.
The preview loads the image straight from the address you gave. If it does not appear, the file cannot be reached publicly at that address, which means the social networks will not see it either. That is the useful part of the test.
Does anything leave my browser?
No. Nothing is sent to a server. The whole tool is a small program that runs inside your browser tab. Once the page has loaded, it keeps working even with the internet switched off.
