Use PNG for sprites that need transparency, packed into sprite sheets to cut HTTP requests. Use JPG or WebP for opaque background art where file size matters more than alpha. GPU compressed formats (KTX2\/Basis) help VRAM, not download size.<\/strong><\/p>\n

For sprite loading in a browser game, the format choice comes down to whether you need alpha transparency and how many separate files the browser has to fetch. PNG is the standard for sprites with transparent backgrounds; JPG or WebP work well for fully opaque art (backgrounds, some UI panels) where smaller file size matters more than per-pixel alpha. Pack individual frames into one sprite sheet image rather than loading dozens of small files – fewer HTTP requests, less loading overhead, and the packing tools (Aseprite’s --sheet<\/code> export, TexturePacker-style JSON) exist specifically for this.<\/p>\n

What about GPU-compressed textures like KTX2?<\/h2>\n

Compressed texture formats (via WebGL extensions, often packaged as KTX2 with Basis Universal supercompression) reduce GPU memory once the texture is decoded, but they are uncompressed on the fly by the shader and are, in general, far worse than PNG or JPG for network transfer. Use them for large 3D scenes or texture atlases where VRAM is the bottleneck, not as a way to shrink your 2D sprite download.<\/p>\n
