Frequently asked questions
Is SHA256 really free?
Yes — SHA256 is 100% free with no limits, no watermarks and no registration. You can use it as often as you like, on as many files or inputs as you need.
Is my data safe when I use SHA256?
Absolutely. SHA256 runs entirely in your browser using JavaScript — your input is processed on your own device and is never uploaded to any server.
Does SHA256 work on mobile devices?
Yes. SHA256 works in any modern browser on desktop, tablet and mobile (Chrome, Firefox, Safari, Edge) — there is no app to install.
Is my data uploaded anywhere?
No. Every DataForge tool runs entirely in your browser. Text and files are processed locally and never sent over the network.
Are the conversions accurate?
Yes — we use the same battle-tested libraries developers use in production (native Web Crypto for hashes, js-yaml for YAML), so output matches what your toolchain produces.
Is there a size limit?
No hard limit. Processing happens on your machine, so even large documents convert in milliseconds.
