File formats you can use in Go Bananas games
What each file type is, what Go Bananas does with it when you upload it, and how to use it in a game.
Images
PNG files in browser games
PNG is a lossless image format with transparency, the usual choice for sprites, icons and interface art in Go Bananas games.
Read →JPEG files in browser games
JPEG (.jpg or .jpeg) is a compact photo format without transparency, best for backgrounds, scenery and photos in Go Bananas games.
Read →WebP files in browser games
WebP is a modern web image format that makes smaller files than PNG or JPEG and still supports transparency, a good default for game art that has to load fast.
Read →GIF files in browser games
GIF is an old, widely supported image format limited to 256 colors, used for simple pixel art and short animations; in Go Bananas games it is usually better as a still image or a sprite sheet.
Read →HEIC files in browser games
HEIC (and HEIF) is the photo format iPhones save by default; most browsers can't show it, so Go Bananas converts it to JPEG in your browser before uploading.
Read →Audio
MP3 files in browser games
MP3 is the format every Go Bananas game plays: upload one, and it's ready for sound effects or music with little to change.
Read →WAV files in browser games
WAV gives the cleanest starting point for game sound, but it's big: on Go Bananas, a WAV must fit in 5 MB, and the site turns it into an MP3.
Read →OGG files in browser games
OGG is a free, compact audio format that works on Go Bananas even on iPhones, because the site turns every OGG into an MP3 that plays everywhere.
Read →M4A files in browser games
M4A is the audio format iPhones and Macs record and export, and you can upload it to Go Bananas as is: the site turns it into an MP3 for your game.
Read →3D models
GLB files in browser games
GLB is the best format for 3D models on Go Bananas: one file holds the mesh, materials, textures and animations, and the site uses it as it is.
Read →glTF files in browser games
A .gltf file works on Go Bananas when it is self-contained; a glTF with separate .bin and texture files needs to go in a ZIP, and either way the site turns it into a GLB.
Read →FBX files in browser games
Go Bananas accepts FBX and converts it to GLB, keeping animations and shrinking textures to at most 512×512 pixels, so your game loads it like any GLB.
Read →OBJ files in browser games
OBJ works on Go Bananas for plain shapes, but its materials and textures are not kept, so for a colored or textured model use GLB instead.
Read →ZIP bundles of 3D models
On Go Bananas a ZIP carries one 3D model with the files it needs, such as a glTF with its .bin and textures or an FBX with its textures; it can't carry a game.
Read →3D scans (Gaussian splats)
PLY Gaussian splat files in browser games
Upload a Gaussian splat .ply to Go Bananas and the site packs it into a lighter .ksplat scene your game can walk through; .compressed.ply files are kept as they are.
Read →SPZ Gaussian splat files in browser games
Go Bananas accepts SPZ splat files and converts them to a compressed PLY thinned to 300,000 splats, which your game loads with the GaussianSplats3D library.
