Free online tools

Yes. All 112 tools listed here are free to use and none of them require an account, a sign-up or an API key from you. The site is supported by advertising and by the paid services Mana Studio sells; the tools are not a trial of anything.

It depends on the tool, and each one says which it is. Most run entirely in your browser — the PDF, image, developer and calculator tools all process what you give them on your own device, and nothing is sent anywhere. The exception is tools that have to ask another service a question: the YouTube tools that read public channel or video data, and the SEO tools that ping search engines or check indexing. Those send the URL or handle you type to our API, which queries the source. Each tool card and each tool page states which of the two it is.

Mana Studio, a web, app and AI development studio based in Warangal, Telangana, India. The tools are built with the same stack we use for client work, and they exist partly because we needed most of them ourselves.

Yes. Anything a tool generates from your own input — meta tags, schema, a merged PDF, a converted image, a calculation — is yours. Where a tool retrieves third-party material, such as a YouTube thumbnail or channel asset, the ordinary copyright of that material still applies and is not ours to grant.
