Markdown Preview is a fast, free, browser-only tool from SnapToolz that helps you render github-flavoured markdown live with safe html output. Files are processed locally on your device — nothing is uploaded to a server. There's no account to create and no usage limit.
Click ‘Use Markdown Preview’ above (or scroll up). The interface loads in under a second — no plugins or extensions needed.
Drag-and-drop files, paste content, or type — depending on what the tool needs. Everything stays in your browser.
The output is displayed instantly. Copy to clipboard or download the file. Refresh to start over.
No. Every tool on SnapToolz runs entirely inside your browser using JavaScript and WebAssembly. Your file is read locally, processed in memory, and the result is offered as a download. Nothing is sent to a server — there isn't one to send to.
There's no artificial limit. Practical limits depend on your device's memory — most tools comfortably handle hundreds of megabytes.
Yes. SnapToolz is a Progressive Web App. After your first visit, the app is cached on your device and every tool keeps working without an internet connection.
Any modern browser with WebAssembly: Chrome, Edge, Firefox, Safari, Brave, Opera. Mobile browsers work too — the UI is fully responsive.
Yes — every tool is 100% free with no sign-up, no watermark, no hidden tier. The whole platform is open source and we have no plan to gate features.
