Texture Channel Extractor Online - Extract RGBA in Browser
Extract R, G, B, and Alpha channels from PNG, JPG, or TGA textures online. Ideal for mask recovery, PBR map prep, and packed texture debugging.
What this texture channel extractor solves
This online texture channel extractor is built for cases where you need to inspect, isolate, and export RGBA channels from a source image. It is useful for debugging packed textures, rebuilding grayscale masks, preparing PBR maps, and understanding how authoring tools stored information across color and alpha channels.
Supported inputs and outputs
- Input textures: PNG, JPG, and TGA files commonly used in game art and material pipelines.
- Output textures: extracted channel images exported as PNG or TGA and bundled for download.
- Workflow fit: useful for inspection, mask recovery, grayscale map generation, and pre-pack validation.
When to use this tool
- Split R, G, B, and Alpha channels from packed textures to inspect masks and material data.
- Export grayscale channels for reuse in PBR authoring, shader debugging, or texture cleanup tasks.
- Verify whether source textures contain usable channel information before repacking or batch processing.
