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.
