How this tool works
Hyphens make UUIDs easier to read, but compact UUID strings are sometimes required for filenames, tokens, database columns, or older integrations.
This tool keeps the original UUID visible so you can compare both forms before copying.
Examples
- Generate a compact UUID for a filename-safe identifier.
- Copy an uppercase no-hyphen UUID for a legacy API field.
Common use cases
Compact database fields
Filename identifiers
Legacy API values
FAQ
Is a UUID without hyphens still valid?
Many systems accept compact 32-character UUID strings, but some APIs require the standard dashed format.
Can compact UUIDs be uppercase?
Yes. Use the uppercase toggle before copying the compact value.
