Is there a way to transfer worlds from PS4 to Windows 10 on pc without buying realms.

Hope you're doing great today despite this Sebastien

Unfortunately nope, right now the only way is uploading the world to realms and then download it in your PC

Hi JTV,

Thanks for reaching out to the forums. We understand you have a question on Minecraft worlds. Unfortunately, items from Windows 10 PC, Xbox, and Mobile do not transfer to PlayStation. The only way to transfer worlds form one device to another is with realms.
Which is currently not available on the PS4 right now.

Thanks,

Brad

Hey! So the only current way to transfer worlds is to have a realms account.

1. Load up Windows 10 Edition, and load your world unto the realm.

2. Boot up the PS4 Edition and Download the Realm world!

Hope this helps!

There is a way of transferring worlds from Mobile to Windows 10.

You will need to start a realm. 30 days free trial.

Upload the world from the mobile to the Realm. Sign in with the same account on the windows 10 version and you can download the world from there.

Right now, PS4 Bedrock Mincraft doesn't support Realms yet.

And Realms are the only way you can transfer your Worlds from one device family to another device family (in your case PS4 to Windows 10, or Switch or Xbox).

So in case PS4 Minecraft gets the necessary update to also support realms, you can either rent a Realm, or if it's a one time transfer you can start a free trial for a Realm.

Upload your PS4 world to the Realm after Realms become enabled, and then connect your Windows 10 device to the same Realm and download the world again.

Be aware that this "disconnects" the worlds, if you keep them locally on your devices. So changes you make on your Windows 10 device will not happen on your world stored on the Playstation 4.

If you want to keep the worlds "in sync" on both devices, you will have to pay rent for a Realm server, and store your world on the Realm server, and connect to that Realm with your devices.

Or you can keep the world on one device, and allow your other devices to connect to that world via Multiplayer. In that case the world is only available when the device is running Minecraft, of course.
