>                 Key: IMAGING-336
>                 URL: https://issues.apache.org/jira/browse/IMAGING-336
>             Project: Commons Imaging
>          Issue Type: Improvement
>          Components: Format: GIF

> Today, if we try to remove or change metadata in GIF images and then convert the GIF back into a bytes, it causes a re-encoding of the entire GIF, which can increase its file size.
> I think it would helpful if there was a way to edit or remove metadata on a GIF without reencoding the other blocks. This should guarantee that GIFs cannot grow after removing metadata.
> If the maintainers of this project feel like this is a worthwhile improvement and are willing to do a new minor release when it's done, I'm interested in helping to bring this functionality into the library.
