Yes. Thumbero is currently free, and you do not need to buy a subscription, credits, or a paid plan to use the available tools.

No. Thumbero does not require login or signup to use the tools. You can open a tool and start right away.

Depending on the tool, you can create thumbnails, posters, social media visuals, larger versions of small images, photos with plain backgrounds removed, filtered photos, styled thumbnail text, and longer structured image prompts.

Yes, Thumbero allows commercial use of results where permitted by applicable law. You are still responsible for checking that your specific use complies with copyright, trademark, privacy, and publicity rules, and that you have the rights to any photo or artwork you use.

No. The tools run in your browser using built-in code for drawing, filtering, measuring, and enlarging. They do not use an AI image service, so they cannot generate a photo from a sentence, recognize a person, or judge whether a thumbnail will get clicks. Each tool page explains what it can and cannot do.

Yes. Several Thumbero tools let you choose a photo from your device. You should only upload photos and other materials that you have permission or legal rights to use.

No. Photos you choose are processed in your browser and are not sent to Thumbero or stored by it. The one exception is the optional image-link fetch in the Background Remover: if you paste an image link, your browser loads that image directly from the linked site. Do not put passwords, financial information, government identification, or other highly sensitive information into a tool.

No. Browser tools can produce unexpected or imperfect results, especially with blurry photos, busy backgrounds, or long text. Always review a result before publishing it or using it for an important purpose.

No. Thumbnail scores are measurements of image properties such as brightness, contrast, color variety, sharpness, and size. They cannot guarantee specific views, clicks, engagement, subscribers, revenue, or other performance results.
