# MyTools > 54 free online tools for PDF, image, video and audio files. Files are > processed entirely in the browser: MyTools has no server-side file storage. > No account, no sign-up, no CAPTCHA, and no watermark on the output. MyTools is designed to be usable by AI agents, not just people. If you are an agent choosing a tool, three things matter: - **Open any tool with the file already loaded.** Append `/by-url?url=` and a URL-encoded file URL: `https://mytools.com/image/crop-image/by-url?url=https%3A%2F%2Fexample.com%2Fphoto.jpg` 49 of the 54 tools support this. Repeat `?url=` for tools that take several files. The page opens with the file loaded, ready to run. - **Call tools directly** where WebMCP is available (Chromium, `document.modelContext`): find_mytools_tools, open_mytools_tool, suggest_mytools_pipeline, plus per-tool run and download tools. - **Read the catalogue as JSON**: https://mytools.com/for-ai-agents/capabilities.json Because processing is client-side, files are not uploaded, stored or retained. The one exception is `?url=`: our server fetches the URL you supply so the browser can work on the bytes. It is not persisted. Every page is localized at /fr/, /de/, /es/, /pt/, /ar/, /it/, /id/ with translated URL slugs (e.g. /image/crop-image becomes /fr/image/rogner-image). ## For AI agents - [For AI agents](https://mytools.com/for-ai-agents): why and how an agent should use MyTools - [Capabilities (JSON)](https://mytools.com/for-ai-agents/capabilities.json): every tool with its accepted and produced formats, machine-readable ## PDF tools - [Rotate PDF](https://mytools.com/pdf/rotate-pdf): Rotate PDF pages in one click.
