Frequently asked questions

Which UUID version is this?
Version 4 — randomly generated per RFC 4122, using the Web Crypto API's crypto.randomUUID.
Can I get UUIDs without hyphens?
Yes — tick 'Remove hyphens' for the 32-character compact form used by some database columns.
Are my files uploaded to a server?
No. Files are processed directly in your browser using JavaScript and WebAssembly. Nothing is uploaded to our servers, so your documents never leave your device.
Does it work on mobile?
Yes. The tools run in any modern browser on desktop, tablet, or mobile (Chrome, Edge, Safari, Firefox). Very large files may be slower on low-end phones.
