Greenshot is one of the oldest but also well known screenshot and image annotation tools. It's open source and not really supported well. It only works on Windows (not on Mac or Web) and hasn't been updated in over a decade. Yes, it's completely free, but if you want a screenshot and image annotation tool that does all you need without the bloat, then Greenshot is not the best choice.

The best alternative is Markup Hero. Try it instantly — no signup required.

Say Hello to Productivity

Whether you're using screenshots and markups to enhance your blog posts or create engaging content marketing or providing stellar customer support or any of the million use cases Markup Hero covers, you will be happy you switched.

The product is lightning fast, easy to use and rich with features. All of our editing tools are web based which means you can access your screenshots and annotations from anywhere. Our screenshot app works on Mac and Windows but all your files are stored securely in the cloud and can be instantly shared via a link or just copy your markup to clipboard and paste it anywhere.

One of the most useful features of Markup Hero is the ability to save all of your work and organize your annotations. Compared to Greenshot and other annotation tools who flatten your markups immediately, you'll never again have to re-create a markup. Once you take a screenshot and add annotations, it's saved to your history and you can edit, share and duplicate freely.

Our Annotation Tools Rock

Just about every screenshot tool out there will let you add arrows, text and boxes. But we're taking things further. You can create text with a background color or just outlined.

Plus, you can annotate images and PDF's (more to come soon). Quickly toggle boxes and circles from outline to filled in. Change colors and line thickness. Even past images on top of markups — Greenshot and other competitors don't offer that.

Or try our multi-page features. Yes, you can add more than one image or PDF page to the same markup then add annotations and share the entire folder. It's super useful for walkthroughs, help documents and providing website feedback.

What Users Have to Say About Markup Hero

Many of our users love our Slack integration. Markup Hero is the only Slack app to offer instant "click-to-annotate" images and PDF's directly from a Slack conversation. Plus, when you post a Markup Hero link into Slack you'll get an instant preview with annotations.

Users also love our web based annotation tools. They can access from anywhere at anytime and easily share markups with colleagues and friends.

Why not just try it for yourself. You can instantly upload an image or PDF and add your markup without creating an account, entering any payment info or even downloading anything. It's 100% instant. Give it a whirl here.
