SyncS3 gives Gravity Forms users the ability to push any files to any Amazon S3 bucket. When files are submitted through a form, you can send those files to any Amazon account, and any S3 bucket. Simply add your Amazon AWS credentials, chose which fields should push to S3, and save.
You can even send different file-upload fields to different accounts or buckets. SyncS3 gives you flexible control over which accounts/buckets for sending your files by controlling the settings on global, form, and field levels.
If it doesn’t make sense for you to also store the files locally, you can set the files to be removed from your server after they’re uploaded to S3. This helps reduce the overall disk space of your website.
SyncS3 also includes a WP CLI command for processing all entries, so you can effortlessly send all of your files from all of your form entries to your S3 buckets.

The S3 Image Optimizer will optimize all your images in 1-1,000+ Amazon S3 buckets using the EWWW Image Optimizer. Since EWWW IO integrates directly with plugins like WP Offload Media, S3 IO is generally for folks who use a solution other than WP Offload Media to put their images on S3. But, if you have 20 sites sharing an S3 bucket, or have lots of buckets, and you would want to optimize them all from one place instead of 20 different sites, this is the plugin for you.
S3 IO features a web-based bulk optimization process, and a WP-CLI interface for massive buckets. S3 IO works with any S3-compatible storage service including Linode, Backblaze B2 and Digital Ocean Spaces.
