• active_storage_validations

  3 972 8.5 Ruby

  Do it like => validates :photos, attached: true, content_type: ['image/png', 'image/jpg', 'image/jpeg'], size: { less_than: 500.kilobytes }, limit: { min: 1, max: 3 }, aspect_ratio: :landscape, dimension: { width: { in: 800..1600 }

Project mention: Resize images before uploading them with Ruby on Rails Active Storage | dev.to | 2023-04-30

I recommend pairing this approach with the active_storage_validations gem and adding a validation to the attachment field to ensure that the attachment that you'd like to resize is an image. Ideally, an application should gracefully handle invalid input with useful error messages.
