Image Transformations and Signed URLs
Serve resized, optimized images on the fly and grant temporary access to private files using Supabase Storage signed URLs.
Smarter File Delivery
Supabase Storage can transform images on request and create signed URLs for time-limited access to private files. Both reduce custom backend work.
Public vs Private Buckets
Public buckets serve files via a permanent URL. Private buckets require a signed URL or an authenticated request, controlled by policies.
