BLP Image Preview

Preview Blizzard .blp texture files directly in VS Code — no external tools required.

Features

• Opens .blp files as image previews automatically
• Displays image metadata: format, alpha depth, mipmap count, and file size
• Supports all BLP2 compression formats:
  • DXT1 — no alpha or 1-bit alpha
  • DXT3 — explicit 4-bit alpha
  • DXT5 — interpolated 8-bit alpha
  • RAW1 — palettized (256-color)
  • RAW3 — uncompressed ARGB8888
• Respects VS Code's light/dark theme for the preview background

Usage

Open any .blp file in VS Code. The preview renders automatically in place of the text editor.

Supported File Types

Requirements

No external tools or runtimes required. Decoding is handled entirely within the extension using the @pinta365/blp library.

Known Limitations

• Only the main mipmap level (level 0) is displayed
• BLP1 files (Warcraft III pre-TBC era) are not supported
