Free Stone and Rock Textures (PBR, Seamless)
Stone covers a huge range, from polished marble to a cliff face, and the free libraries have both ends well covered. Displacement matters more here than anywhere else: a flat quad with a stone colour map reads as wallpaper, while the same texture with its normal and displacement maps reads as rock. If you're targeting the web, a normal map alone gets most of the effect for a fraction of the cost.
Everything here is free to download from the source site. These results come from Poly Haven, AmbientCG. Licences vary by file and are shown on each card. Nothing is hosted by us, and every link goes to the original page so you get the current version and the real licence terms.

Using these textures in a game
A PBR set is usually four or five images: base colour, roughness, normal, ambient occlusion, and sometimes displacement or metalness. You need at least colour, roughness, and normal for a surface to react correctly to light. Poly Haven and AmbientCG both offer several resolutions per texture, and 1K is the right default for anything running in a browser tab.
Texture memory, not file size, is what kills web performance. A 2048×2048 PNG is 16 MB in video memory no matter how small the download was. Convert textures to KTX2 and they stay GPU-compressed in memory, which typically cuts that by four to eight times. That single change usually does more for load time and frame rate than reducing polygon counts.
Licences, briefly
CC0 means public domain: use it commercially, modify it, ship it, no credit required. That covers everything from Kenney, Quaternius, KayKit, Poly Haven, and AmbientCG.
Freesound and OpenGameArt host a mix. Some files are CC0, others are CC-BY (credit required) or CC-BY-SA (credit required and derivatives must carry the same licence, which is a real constraint on a commercial game). The licence is set per file by whoever uploaded it, so check the source page before you ship.
The complete guide to game asset licences covers what each one actually requires and where teams usually get it wrong.
