The story
About the 404 Error 3D icon
This 404 Error 3D Icon is ideal for website error pages, UI kits, hosting platforms, and support content that needs a clear visual for missing pages. The isometric 3D style makes technical messaging feel more engaging and polished, and it is free to download for web and app projects.
The 404 Error icon is part of Thridy's isometric 3D collection: soft studio lighting, gentle shadows and a clean silhouette that stays legible from hero sections down to 48-pixel UI slots. It ships as a transparent-background PNG, so it drops into any design without masking or background removal.
Designers most often reach for it in SaaS marketing sites, developer documentation, feature comparison tables and product tours. Because the whole Thridy set shares one rendering style, the 404 Error icon pairs cleanly with the rest of the Technology category when you need a consistent set rather than a single image.
It is a strong fit for software companies, IT services, AI products and hardware brands - anywhere themes like 404 error, page not found, website error, web UI appear in your product or content. Download it free, or request a custom variation if your project needs a different angle, color or companion icon.
