ABOUT THE TOOL
Minecraft Skin File Checker
The checker reports properties of the supplied texture, including base-layer transparency. A file check does not replace an actual game-client import test.
One way to get started.
Check a 64×64 Classic skin before importing it to spot transparent base pixels.

What the Minecraft skin file checker examines
The Minecraft skin file checker inspects the PNG texture itself before you try it in a game. It accepts square 64×64 and 128×128 skin textures and checks the pixels against the arm model you choose. It does not analyse a screenshot or create a new skin. Pick Classic for four-pixel arms or Slim for three-pixel arms; a wrong selection can make the inspection less useful because the arm layouts differ.
The report counts non-opaque pixels in required base-layer faces and partially transparent pixels anywhere in the image. Fully transparent areas outside those required faces can be intentional: an empty outer layer is normal. The checker also displays a SHA-256 fingerprint of the exact uploaded file, so you can compare reports for the same bytes. It cannot tell you whether a design looks good, whether you have permission to use it, or whether a particular game or device will import it.
Read the result and fix a problem
Start with the original PNG exported by your editor. Select its source model, run the check, and read both counts. If the required base pixels are transparent, open the file in the skin editor and paint the missing base-layer areas opaque. If partial alpha is reported, look for pixels with opacity between fully transparent and fully opaque and replace them with an appropriate solid or fully transparent pixel. Export a new PNG and run the Minecraft skin file checker again.
The color-coded Classic template shown below is an actual example checked with this tool. It has a 64×64 texture, zero transparent required base pixels and zero partially transparent pixels. The colors identify body regions; they are a guide, not a finished character. Your own result can differ. A passing report means these file checks passed; always inspect the character and test the import in your intended game client.
Choosing a file and understanding the limits
A 64×32 legacy texture is not a square modern skin, so convert it with the legacy option in the skin converter before checking the resulting 64×64 PNG. A 128×128 file can be inspected, but the checker does not establish HD skin support in a particular client. Selecting a model does not change the image: it tells the checker which base faces to inspect. To change arm layouts, use the converter and review the seams afterward.
The tool sends the selected file for inspection and returns a report; checking does not paint or overwrite your original. Keep a copy before editing, particularly if you want to compare versions. If the file cannot be decoded or the dimensions are unsupported, export a fresh PNG at the correct size instead of renaming another image format. For a pack, check each source skin before assembling it and then test the resulting pack on your intended Bedrock device.

Does a passed check guarantee game compatibility?+
No. Import behavior depends on the game client and device.
Which file should I upload?+
Use the original skin PNG rather than a screenshot of the character.
