Generate a UUID Without Hyphens
Get a UUID as 32 hex characters with no hyphens. Useful for filenames, tokens and systems that reject the dashed format.

Generate a UUID Without Hyphens
The canonical UUID string has four hyphens. Some APIs, object keys and filenames want the same 32 hex digits with the hyphens stripped. Generate a normal UUID and remove the dashes, or copy the compact form below.
Worked example: Dashed and compact forms of the same ID
UUID
550e8400-e29b-41d4-a716-446655440000 550e8400e29b41d4a716446655440000
Validator result
✓ Valid UUID Version: 4 — random Variant: RFC 9562 (10xx) compact: 550e8400e29b41d4a716446655440000
Practical tip
Re-insert hyphens at 8-4-4-4-12 before validating. Most UUID libraries reject the compact form until you restore the dashes.

Generate a UUID Without Hyphens FAQs
Is a 32-character hex string still a UUID?
Yes, if it is the same 128 bits. The hyphens are presentation only.
How do I add hyphens back in JavaScript?
Use a replace such as s.replace(/(\w{8})(\w{4})(\w{4})(\w{4})(\w{12})/, "$1-$2-$3-$4-$5").
