Frequently Asked Questions
PKM is a texture container format developed by Ericsson for storing ETC1 (Ericsson Texture Compression) compressed textures. It's commonly used in Android game development for efficient texture storage.
PKM files specifically support ETC1 compression, which provides 6:1 compression ratio for RGB textures. ETC1 is widely supported on mobile GPUs and offers good quality-to-size balance.
Yes, absolutely. All PKM file processing happens entirely in your browser using WebAssembly. Your files are never uploaded to any server, ensuring complete privacy and security.
The decoder can handle PKM files up to 100MB in size. Most game textures are well below this limit, but extremely large texture atlases may need to be split.
Yes, the decoder supports PKM files with mipmap chains. All mipmap levels will be parsed and can be viewed individually in the preview panel.
The PKM decoder works in all modern browsers that support WebAssembly and WebGL, including Chrome, Firefox, Safari, and Edge (version 79+).
Once the page is loaded, the core decoding functionality works offline. However, initial page load requires an internet connection to download the WebAssembly decoder module.
To create PKM files, you'll need to use our encoder tool or other texture compression tools like Mali Texture Compression Tool or PVRTexTool that support ETC1 compression and PKM output.
