The editor loads in the browser you already use.
2. Stage edits
Inspect the typed tree, change values, reorder supported tags, and review what differs from the opened file.
3. Download a copy

What “no download” means
The tool stays online. Your edited file downloads locally.
The application code loads as a website, while the Minecraft file remains on your device. When you finish, the result is generated in the browser for you to download.

Common questions
Frequently asked questions
Can I download Chunkweave as a desktop app?
No. Chunkweave is currently a browser-based NBT editor and does not offer a Windows, macOS, or Linux desktop installer.
Can I use the editor without creating an account?
Yes. The current release does not require an account, login, payment, or cloud storage to open a supported local file.
What does the Download copy button do?
It rebuilds the edited data in your browser and downloads a separate file. It does not download or install the Chunkweave application.
Will the website replace my original file?
No. A website cannot silently overwrite the source file you selected. Chunkweave exports a new copy that you can review and place manually.
