Qualified teams
The winners and runners-up of each of the eight groups in the Copa Sudamericana group stage as well as the third-placed teams of each of the eight groups in the Copa Libertadores group stage advanced to the final stages. The eight Copa Sudamericana group runners-up faced the eight Copa Libertadores group third-placed teams in the knockout round play-offs, whilst the eight Copa Sudamericana group winners directly advanced to the round of 16. 

Seeding
 For the final stages, the teams are seeded according to their results in the group stage, with the Copa Sudamericana group winners seeded 1–8, the Copa Sudamericana group runners-up seeded 9–16, and the Copa Libertadores group third-placed teams seeded 17–24. For the round of 16 draw, the seeds 1–8 made up Pot 1, and the eight knockout round play-offs winners (seeds 9–24) made up Pot 2, keeping their seed. Teams from the same association may play each other from the knockout round play-offs onwards. 

Format
 Starting from the knockout round play-offs, the teams play a single-elimination tournament with the following rules:
 * In the knockout round play-offs, round of 16, quarter-finals and semi-finals, each tie is played on a home-and-away two-legged basis, with the higher-seeded team hosting the second leg (Regulations Article 2.2.3). If tied on aggregate, extra time will not be played, and a penalty shoot-out will be used to determine the winners (Regulations Article 2.4.4).
 * The final is played as a single match at a venue pre-selected by CONMEBOL, with the higher-seeded team designated as the "home" team for administrative purposes (Regulations Article 2.2.6). If tied after regulation, 30 minutes of extra time will be played. If still tied after extra time, a penalty shoot-out will be used to determine the winners (Regulations Article 2.4.5).
