Amazon Simple Storage Service S3 Object Lambda Access Points Icon

Amazon S3 Object Lambda Access Points let you run custom code, like a small program, each time someone accesses an object in your Amazon S3 bucket. This lets you transform the object's data or metadata on-the-fly before it's sent to the user, without needing to download and modify the entire object first. This is useful for things like resizing images, converting file formats, or adding watermarks; it keeps your original data safe in S3 and only delivers a tailored version.
