Change image urls from attachment url to file url in all posts

Hello,

I have a blog wich currently has more than 1,000 posts and after doing some optimization, i noticed one of the editors of the blog inserted images on posts using by default the attachment link. In summary, when a visitor clicks on an image in my blog, the image will point to the attachment url.

I was looking to change the images url from attachment url to the file url. I know that this can be done manually, but since there is more than 1,000 posts, i’d like to know if is there a plugin or any way that i can do this in bulk.

Thanks in advance.
