Maintains image copyright

Does it keep copyright metadata while removing the junk?

Introduction

A common source of needless bloat is the metadata added by cameras and image editing software. Invisible to the user, it can still add double digit percentage to the filesize for no benefit whatsoever. Tooling should remove unnecessary data from web facing content. Emphasis on “unnecessary”. In light of European Union Directive 790, we want to ensure that copyright owners are being properly attributed, and are not being accidently removed from their works by overzealous optimizations.

The Test

We process a ridiculously bloated image. We then check if the metadata of the file was removed. If any was removed, we check if the image's license is in tact. If it is, then we get a pass.

cloudinary

Cloudinary allows you to request the original image, which would include any existent copyright info. But that would also keep all other metajunk.

Thumbor does not have a built in feature for this, but you can manually configure it to remove the metadata you want do not to keep

webflow

As Webflow does not remove any metadata, this test is not applicable.
