What this tool does
Free single-elimination tournament bracket generator for leagues, game nights, office competitions and esports brackets. Paste one player or team per line and the tool builds a complete knockout bracket: it pads the field up to the next power of two with BYE slots, pairs the first round, and labels every round from the opener through the semifinals and final. You choose the seeding. Keep the input order to honor a ranking list, or shuffle with cryptographically secure randomness for a fair blind draw. When the entrant count is not a power of two (6, 11, 23 and so on) the extra BYE slots are placed so the strongest seeds advance cleanly into round two, exactly how a real playoff draw works. The number of rounds is log2 of the padded size, so 8 players play 3 rounds and 16 players play 4. Everything runs in your browser tab, copy the whole bracket as text in one click, and the shareable link rebuilds your roster and seeding choice. 100% client-side, nothing uploaded.

Real-world use cases
Run an office ping-pong or foosball tournament
Twelve coworkers signed up for the lunchtime table-tennis ladder. Paste all twelve names, hit shuffle for a fair blind draw, and the tool pads to 16 with 4 BYE slots so four people skip the first round. You get the full schedule in seconds, copy it to the team channel, and everyone knows who they play first. No spreadsheet, no manual pairing, no arguments about who got the easy side.
Seed an esports or gaming-night knockout
Eight squads are battling for the weekend crown and you already have a power ranking from last week. Keep seeded order so the top squad faces the bottom squad in Round 1, exactly like a real playoff draw, and the favorites stay apart until the Final. Share the link in Discord and every captain sees the same bracket without you screen shotting anything.
Plan a local sports league playoff
A rec basketball league finishes the regular season with 11 teams and needs a single-elimination playoff. Paste the standings in finishing order, leave it on seeded, and the tool pads to 16 with 5 BYE slots so the top five seeds earn a first-round rest. The bracket prints the Quarterfinals, Semifinals and Final so you can book courts and times around it.
Set up a classroom or club competition
Running a chess club tournament with 20 students? Paste the roster, shuffle for a neutral draw, and you get a 5-round bracket padded to 32 with 12 BYE slots distributed across the top seeds. Copy the text bracket onto the whiteboard or hand each round's pairings to the students. The shareable URL lets the faculty advisor reopen the exact same draw.
Common pitfalls
Expecting every round to have full matches when the field is not a power of two. With 6 or 11 entrants some opening slots are BYE advancements, not real games. That is correct, because a BYE means the opponent moves on for free so the bracket can balance to a power of two.
Shuffling when you actually have a ranking. If line 1 is your strongest team, leaving it on seeded protects the favorites until late rounds. Hitting shuffle throws the ranking away and the top two could meet in Round 1 by chance, which is rarely what a ranked playoff wants.
Assuming the round count equals the number of players. It does not. Rounds equal log2 of the padded field, so 8 players is 3 rounds and 16 is 4, not 8 and 16. The padding to the next power of two is what sets the round count, never the raw entrant total.
Privacy
The whole bracket is built by plain JavaScript in your browser tab. The pairing, the BYE padding, the shuffle and the round labels all run locally, and no roster or seeding ever leaves the page. There is no log of who you entered. The one caveat: the shareable link encodes your player list and seeding choice in the query string, so a link pasted into chat will record those names in the recipient server access log. For a confidential draw, use the copy button and paste the text instead of sharing the URL.
