gif toolkit
Every GIF tool, running in your browser.
A free, private GIF toolkit that runs entirely in your browser: convert, resize, crop, optimize and caption GIFs, and build Slack emoji. Nothing is uploaded. Results are kept in a local history so you can grab them again, and every download is named so it can be dropped straight into Slack.
