What's actually shipped on MagicToolbelt, dated and linked.
Correct. Every tool on MagicToolbelt runs entirely inside your browser. Your files exist only in your browser's memory and are deleted permanently when you close the tab. No data is ever sent to any server.
No account, no install, no plugin. Open any tool in a modern browser (Chrome, Firefox, Safari, Edge) and start immediately. MagicToolbelt works on desktop and mobile.
When you finish in one tool, MagicToolbelt can hand your file directly to the next tool — no download or re-upload needed. For example, after cutting a video you can instantly convert it to a GIF with one click. The file passes through your browser's local storage, never through the internet.
All 21 tools are free with no usage limits, no watermarks, and no paywalls. The site is supported by non-intrusive display advertising. Individual tools may have file-size limits imposed by browser memory constraints, which are documented in each tool.
Any modern browser works — Chrome, Firefox, Safari, or Edge. Internet Explorer is not supported. For the best experience, use the latest version of Chrome or Firefox on desktop.
Every tool runs 100% inside your browser — no file ever leaves your device.
