HDR input note
HDR, EXR, and UltraHDR JPEG files can be used as inputs. Most current output paths still tone map into the RGBA8 encode pipeline; use DDS BC6H, KTX2 RGBA16F, or KTX2 RGBA32F when you need to preserve HDR source data as much as possible.

Frequently Asked Questions
Use PVRTC for iOS-only apps (best performance), ETC for Android, ASTC for cross-platform with best quality, or RGBA8 for lossless uncompressed storage.
No, all encoding happens locally in your browser using WebAssembly. Your images never leave your device, ensuring complete privacy.
PVRTC requires square, power-of-2 dimensions (256x256, 512x512, etc.). ETC and ASTC work with any dimensions that are multiples of 4. Uncompressed formats have no restrictions.
iOS natively supports PVR files. Use UIImage or Metal texture APIs to load .pvr files directly. The GPU can decompress PVRTC textures in hardware.
No, each PVR file contains one texture with one compression format. However, you can easily re-encode to test different formats.
PVRTC 4BPP RGBA, ETC2 RGBA, and ASTC all support alpha channels. The encoder will automatically detect and preserve alpha information.
