BlockFinder
Minecraft coordinates from a screenshot, on flat ground. For Java Edition.
Upload a Java screenshot, mark the blocks you can read, and this page lists the coordinates in the area you name that match them. It never asks for your seed.
Drop a screenshot here, or click to choose one. Full window, saved as PNG.
Rotation
Pick the tile that matches the crop, then confirm it below. Keys 1 to 4 also work.
How a Minecraft screenshot gives away your coordinates
Most blocks in Java Edition are drawn with one of four rotations, and the game chooses the rotation from where the block sits. That is why two grass blocks side by side can look turned differently. The choice follows the same rule in every Java world, so a picture of the ground already contains a little of the position it was taken from.
The page reads that. You put the four corner handles on a rectangle of ground, click the blocks you can recognise and pick the rotation of each one. Then you type the area you think you are in, and the search keeps only the positions that would turn every marked block exactly the way your picture shows.
What the picture needs to work
Flat ground is the one hard requirement. A slope moves the corners, so the readings stop agreeing and the list comes back empty. Save the window as PNG instead of photographing the screen, because a photo adds its own angle. Include enough ground that you can name at least sixteen blocks, and set your Minecraft version before you start so the page compares against the right textures.
Three captures ship with the page and each one shows its real coordinates once loaded. Run one of them end to end and you will know whether the ground you are standing on will work before you mark a single block of your own.
What you get back, and what to do with it
Results are positions to check, not a pin on the map. Each row carries the coordinates and the direction the picture was taken from, and you copy the numbers into the game to stand there. If two positions would look identical from where you stood, the page cannot choose between them, because the picture does not say which one you were in.
A long list means the area is too wide or you marked too few blocks, so narrow the numbers or mark a few more and run it again. A search that finds nothing usually means the version is wrong, or one block was read the wrong way around.
BlockFinder is Java Edition only
Bedrock does not turn blocks the way Java does, so a Bedrock screenshot has nothing for this page to read. On Bedrock, start from the seed with the seed finder, or from structures you have already found with the seed cracker.
Frequently asked questions
How do I find my coordinates from a Minecraft screenshot?
Take a screenshot in game, drop it on the page and drag the four corner handles onto blocks you can identify. Then click each block you want to read and pick the rotation that matches. With sixteen blocks or more marked, open the Find tab, type the area you think you are in and run the search.
Does BlockFinder need my world seed or the world file?
No. A block's rotation comes from its own position, so the picture is enough, and it works on a world whose seed you no longer have. Nothing here needs the world file or operator rights either, so any Java screenshot works, including one from a multiplayer server. A server that moves or replaces blocks with plugins can hand you a picture the normal rules do not explain, and then the list comes back empty or short.
Can BlockFinder tell me exactly where I am?
It narrows it down, and then you finish the job. The picture has nothing that points at one place, so the search returns every position in your area that fits your readings. You check them in game and the world settles which one is yours.
Does it work on Bedrock Edition?
No. Bedrock has no equivalent signal, so there is nothing in a Bedrock screenshot for the page to read. On Bedrock you start from the seed, or from structures you already found.
Do I need to install anything or use a resource pack?
No. The picker shows the block's own texture in each rotation the game uses, and you choose the one your crop matches. Nothing to install, and no account.
Why does it need so many blocks?
Each block you read crosses out every position that would have turned it differently. A couple of blocks still leave most of the area standing, so the page asks for at least sixteen and lets you mark up to sixty-four. Stone and bedrock cut less than the rest, because the game only gives them two rotations instead of four.
Which Minecraft versions does it support?
Java Edition 1.8 and later, with separate entries for Sodium users. Pick your version before you mark anything: older versions turn blocks by a different rule, and the textures changed in 1.13.
