An End portal frame is an indestructible block, 12 of which form an End portal. Eyes of ender must be inserted into all 12 empty frames (if not already present upon generation) for the portal to activate and allow passage into the End dimension.

End portal frames, like bedrock, are unobtainable and unbreakable in Survival or Adventure mode. It can be obtained only by accessing the creative inventory or commands.

12 End portal frames generate naturally to form the End portal in each stronghold End portal room, over a pool of lava with a staircase containing a silverfish monster spawner. The frames generate in a 5×5 square formation, with 3 frames on each side, without the corners. Each End portal frame generates facing inward, with a 10% chance of containing an eye of ender.

Each stronghold contains an End portal. In Java Edition, each world contains exactly 128 strongholds, so a total of 1,536 End portal frames are generated. In Bedrock Edition, there are infinitely many strongholds in each world, so the number of End portal frames that may generate is also infinite. In Legacy Console Edition, there was only one End portal per world, so 12 End portal frames were generated.

There is an extremely low chance (10^-12 or 10^-10% or one in a trillion) for all twelve End portal frames to be filled in strongholds.

The chart below shows the probability of having each number of eyes of ender filled in (some values may be rounded).

Calculating the chance for a specific amount of eyes generating is done with the probability mass function:

P(X=number of eyes) = with k being the number of eyes.

Using eyes of ender on End portal frames inserts them to the top of the frame if it is not inserted previously.

An End portal frame has a front face that faces the player when placed. Although the facing is almost invisible (one can distinguish only 2 rotations of End portal frames), all End portal frames must be placed correctly and face inward in order to be able to activate the End portal, and if all of the frames have eyes of ender inserted, the portal activates, replacing the inner 3×3 space with End portal blocks.

If an End portal is built in the End, entities are teleported back to the world spawn point in the Overworld, similar to the exit portal.

End portal frames output a redstone comparator signal of 15 when an eye is present. If there is no eye in the frame, it outputs a signal of 0.

End portals frames emit a light level of 1.

End portal frames cannot be pushed by pistons. They also cannot be pushed nor pulled by sticky pistons.
