Your image stays in the browser
When you choose or paste an image, the page uses it for the local preview and export flow. The tool does not upload the image to a server or send it to an image-processing API.
SITE POLICY 04
Privacy, in plain English.
Thumbnail Tester is designed to keep the image you preview on your own device. This page describes the current behavior and the advertising plan.
No account is required
You can use the tool without registering or signing in. The static site does not ask for a password, payment information, or an access token.
Hosting and site requests
The pages are delivered as a static site through Cloudflare Pages. The hosting provider may process ordinary request data needed to deliver the site, protect the service, and keep it available under its own policies.
Third-party advertising plan
No third-party ads are displayed in the current tool. The site may add third-party advertising in the future. If ads are introduced, advertising providers may use cookies or similar technologies under their own policies, and this page will be updated before that change.
Changes to this page
If the tool starts using analytics, ads, forms, or any other data practice that changes the explanation above, this page will be revised to describe the new behavior.
