Compress & Upload for Safari is free on App Store

Compress & Upload for Safari normally costs $1.99, but you can get it free on the App Store for a limited time. It's a Safari extension for macOS that puts an overlay on image upload fields on web pages. You can compress an image right there and upload it, so you don't need to open another app or use a separate website first.

Everything is processed locally in your browser. That makes it useful for Mac users who often upload screenshots, photos or other images and want smaller files with less hassle.

If you claim it while it's free, it's tied to your Apple account like any other App Store download. That means you can download it again later after the deal ends.
