Are my files uploaded to a server?
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.
Is there a limit on what Timestamp Converter can handle?
There's no artificial limit. Practical limits depend on your device's memory — most tools comfortably handle hundreds of megabytes.
Does it work offline?
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.
Which browsers are supported?
Any modern browser with WebAssembly: Chrome, Edge, Firefox, Safari, Brave, Opera. Mobile browsers work too — the UI is fully responsive.
Is SnapToolz free?
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.
