convert_format_thumbnail

🎨 Convert formats and create thumbnails

You can convert images to different formats or apply operations like cropping. Combine options like format and resize_to_fill to generate square thumbnails.

# In a model or controller
def avatar_thumbnail
  user.avatar.variant(format: :png, resize_to_fill: [100, 100]).processed
end

Use the resulting variant in views to serve optimized thumbnails.
