How to delete EXIF ​​(camera) data from a carrier image?

Question

Somebody knows? There was a special config command with paperclip.

Removing camera data from an image is saved 25-30 Kbytes per file. This is very sensitive if we make many versions (large, small ...). In small images, the actual file size without this information can be 5-6 times smaller.

Thanks in advance!

Carrierwave is very flexible and allows you to create your own processors. With MiniMagick, we can use several options for mogrify command line, one of which is strip:

 class ImageUploader < CarrierWave::Uploader::Base include CarrierWave::MiniMagick version :small do process :resize_to_fill => [100, 100] process :strip end def strip manipulate! do |img| img.strip! img = yield(img) if block_given? img end end end
