I want to make a Minecraft texture pack in 1.17 by editing the default Minecraft 1.17 textures but I don't have Minecraft. I can't download Minecraft because I am 12 and don't have money to pay for it so I searched it on Google and only found alternatives. Is there any way to download the default Minecraft 1.17 textures?
You can extract the minecraft textures from the minecraft JAR file, you should be able to find the latest 1.17 snapshot JAR file downloads on the Minecraft Wiki.
You can then use an archive utility (like 7-zip) to extract the JAR and edit the textures (which are located in the
assets/minecraft/textures folder), then just copy the folder to the place you want to make your texture pack.
You can download the Default texture pack 1.17 and older versions from https://texture-packs.com/resourcepack/default-pack/
