Get a fresh, random GUID (also called a UUID) for every line below. Add lines to generate more, delete lines to generate fewer. Each is a version 4 GUID made in your browser with the built-in crypto random source, so nothing is uploaded and no two are the same.
The rule above replaces each line with the {guid} token, which becomes a new value on every match. Ask for a different shape with a suffix.
{guid} -> 3f2504e0-4f89-41d3-9a0c-0305e82c3301
{guid:upper} -> 3F2504E0-4F89-41D3-9A0C-0305E82C3301
{guid:n} -> 3f2504e04f8941d39a0c0305e82c3301 (no dashes)
{guid:short} -> 3f2504e0 (first 8)
{guid:braces} -> {3f2504e0-4f89-41d3-9a0c-0305e82c3301}Change {guid} in the rule to any of these to get that format. The values shown are illustrative; every GUID you generate is random.
Each GUID is a random version 4 UUID with 122 random bits, so a collision is astronomically unlikely. Ideal for IDs, keys and unique file names.
The values come from your machine's built-in cryptographic random generator. Nothing is requested from a server and nothing is logged.
Every line becomes its own fresh GUID, so you can generate a whole batch at once. Add or remove lines to set how many.
Download this exact setup as a ready-made GUID generator profile. Better still, the Windows app can type a brand-new GUID straight at your cursor with Insert mode, so you never break your flow to open a generator again. Same engine as above, entirely offline.
Each line in the box above is already a fresh GUID. Add a line for another, or delete the ones you do not need, then copy the result. In the Windows app you can stamp one at the cursor on a hotkey.
None in practice. GUID (globally unique identifier) is Microsoft's name for what the standard calls a UUID (universally unique identifier). This page makes version 4 (random) UUIDs, which is what most systems mean by a GUID.
Yes. A version 4 GUID has 122 random bits, so the chance of ever generating the same one twice is negligible, and they are generated with your browser's cryptographic random source rather than a weak random function.
