Can you transfer pocket edition skin to java edition made in-game character creator? [duplicate]

I have a skin on the bedrock/windows 10 edition of the game that i would like to use for my java edition. I made the skin in the skin customizer within the game. Is there a way to download or save the skin?

tl;dr - Yes*

In Bedrock, unlike Java Edition, skins are a little messy; there's several types of skins available;

Regular Skins

If you used an imported skin, you can find them in [Data Root]\minecraftpe\custom.png of your internal storage. On:

Windows 10, this is: %localappdata%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\
Android, this is: /data/data/com.mojang.minecraftpe/files/
iOS (you can access a sandboxed version of this via iTunes Sync), but the actual file location is: /var/mobile/Containers/Shared/AppGroup/com.mojang.minecraftpe or /Apps/com.mojang.minecraftpe/Documents/games/com.mojang/ (depending on whether you are using sanboxed or rooted/jailbroken).

Store Skins

There is this workaround (scroll up or down, depending on your sort settings) that allows you to access your skin, if it is a standard model skin.

However, some skins introduce custom models and higher texture resolution which cannot be transferred over to Minecraft Java Edition.

You can find them in the premium_cache folder, and under skins of your Minecraft storage directory, as above. However, they are encrypted.

There are however mods that allow the usage of higher resolution skins, but must follow standard model formats (means no custom models or parts), should you get them decrypted.

Edit: It is possible to get skins of this type through custom add-ons, which are basically the same, but obviously not store-bought.

Character Builder

First of all, this is a little more trickier. For most of the parts in Bedrock edition, they add extra geometry to your character. This means you can't directly transfer it to a Java Edition character. Instead, you'll probably have to recreate it using the textures, which are also found in the premium_cache folder, under persona.

How do I decrypt?

"Windows does not recognize this file format."

You don't. Or at least, you are not supposed to be able to decrypt them due to DRM. You could try recreating it from screenshots/eye.

I took a while but i did find this method:

Ok, so. First you have to join a server that has Floodgate 2.0 on it (for example the GeyserMC test server: test.geysermc.org (Bedrock port 19132)). You can do it without Floodgate 2.0, but that just makes it harder. Make sure to replace everything surrounded by asterisk with you info.

Then we need to find your xuid. This can be done using: https://api.geysermc.org/v1/xbox/xuid/*gamertag*

This will give you your xuid. You can use that xuid for the following endpoint: https://api.geysermc.org/v1/skin/*xuid*

This will give you quite a bit of info, but you're interested in texture_id. Then you can go to http://textures.minecraft.net/texture/*texture_id*

You can download that image and use it for your mc acc

As of right now, Diehe's solution does not work. There is another way to access a bedrock skin in Minecraft through GeyserMC/Floodgate. It requires a Java account and a Bedrock account.

Log into any server that uses GeyserMC/Floodgate on both Java and Bedrock. I used test.geysermc.org.
Check that, from the Java player's perspective, the Bedrock player has the desired skin. It may take several hours to a day for a skin to display properly after the Bedrock player logs into a GeyserMC/Floodgate server for the first time¹.
Once you have confirmed that you see the skin that you want, close the games and enter the Java Minecraft directory. From %appdata%/.minecraft/assets/skins, there exist folders containing every skin that has been downloaded by your client. Sort by date modified and open the latest folder. There may be more than one from the server you joined depending on the number of players present.
Add .png to the end of the file in the folder. Open it in an image viewing software to confirm if it is the skin you're looking for. If not, check more folders.

If you want to convert more than one skin, it may be necessary to join a new server for each individual skin.

I was able to get a basic skin from the Microsoft Store for use in Java using these exact steps. Hope this helps!

¹ From what I understand, there is a third-party service used by Geyser that adds the Java representations of the skins of Bedrock clients to a queue. The skins are put onto real Java Minecraft accounts to be uploaded onto the Mojang servers. If you cannot see the Bedrock skins from your Java player's perspective, it may be that the skin is still in the queue waiting to be uploaded. Wait a day or so and check again.
