Thridy.com

Thridy is a library of more than 12,000 free 3D icons for designers and developers. Its collection spans 29 categories, including technology, business and finance, food and drink, animals, transportation, health, and education. Icons are provided as transparent PNGs and share a consistent visual style, with matching lighting, depth, and detail to help teams create cohesive interfaces and designs.

Users can search the library, browse curated packs, or request a missing icon; requested designs are added for everyone to use. The icons are available for personal and commercial projects, including products, client work, presentations, and marketing, with attribution requested on the free plan. Reselling or redistributing the icon files as an asset pack is not permitted.

Thridy also offers paid plans that remove the attribution requirement and provide additional features, including higher daily download limits and access to CDN delivery. Beyond its icon library, the site provides browser-based image tools for tasks such as compression, conversion, resizing, cropping, and QR code generation; these tools run locally in the user’s browser
