Predictable thumbnails
Generate fixed card, listing, and search-result images without storing every derived file.
ugc image optimization
Optimize user-uploaded images without rebuilding uploads
Skymage helps marketplaces, SaaS apps, communities, and directories turn unpredictable user uploads into predictable thumbnails, profile images, galleries, and hero variants.

why ugc is different
User uploads rarely arrive in the shape your UI needs
Users upload screenshots, phone photos, logos, avatars, listing photos, portfolio images, and documents in inconsistent sizes and formats. Skymage lets your UI request consistent variants from the public source URL.
Modern output formats
Serve WebP or AVIF variants from mixed JPEG, PNG, and user-uploaded originals.
Small rollout surface
Start with one repeated upload pattern before touching the whole media pipeline.
best first tests
Pick one upload pattern with visible repetition
The fastest proof is usually a page that repeats the same type of user media many times: listings, profiles, portfolios, galleries, search results, or dashboard previews.
| Surface | Skymage URL pattern |

rollout path
A low-risk UGC image rollout
Choose one repeated page
Use listing cards, profile pages, search results, or a dashboard gallery.
Map real dimensions
Record the desktop and mobile dimensions that user uploads actually render into.
Swap the URL builder
Route that one upload pattern through Skymage with width, fit, format, and quality parameters.
Measure before rollout
Compare transferred bytes, image dimensions, cache behavior, and visual quality before expanding.
