UUID Generator Without Dash
- Browser-based
- No signup
This UUID generator without dash produces 32-character hexadecimal strings without hyphen separators. Useful for MongoDB ObjectId-style keys, compact filenames, and APIs that reject dashed UUID formatting.
Hyphenless UUIDs are the same 128 bits—only presentation changes.
Some databases store UUIDs as binary(16) internally regardless of string format.
100% Client-Side
Your data never leaves your computer.
How to use this tool
Generate a UUID on the base tool, remove hyphens manually or use compact output if offered, then copy the 32-character hex string.
Worked example
Example: convert `550e8400-e29b-41d4-a716-446655440000` to `550e8400e29b41d4a716446655440000` for a Redis key namespace.
When to use this
- APIs requiring 32-character hex IDs.
- Compact URL paths or filename prefixes.
- Legacy Java or PHP systems expecting no dashes.
Common examples
- Generate v4 UUID for a new database primary key in local seed scripts.
- Batch of five UUIDs for mock API fixtures in integration tests.
- UUID for trace id in log correlation examples in documentation.
- Ten UUID v4 values → seed rows for local integration test database.
- UUID v7 batch → ordered IDs for event-sourcing demo data.

Common mistakes
- Mixing dashed and dashless formats in the same table without normalization.
- Truncating hex strings and breaking uniqueness guarantees.
- Assuming dashless implies a different UUID version.

How it works
Choose UUID version 4 (random) or version 7 (time-ordered), how many to generate, and formatting options. UUIDs are created in your browser with the Web Crypto API and are not stored or sent to a server.
Limitations
Results are based on the inputs you provide and may not cover every edge case. This tool is for general use and is not professional advice.
Privacy and file handling
Your data is processed in your browser and is not uploaded to our server.

Frequently asked questions
Is a dashless UUID still RFC 4122?
Yes—the bits are identical; hyphens are optional in many serializers.
Can I add dashes back later?
Yes. Insert hyphens at 8-4-4-4-12 positions to restore standard formatting.
Case sensitivity?
Hex is case-insensitive for comparison, but stay consistent within a project.
