As a Mac user, you likely find yourself needing to take screenshots on a regular basis - whether it's to share an excerpt from an article, showcase a tweet, or point out a UI element to your team. The built-in macOS screenshot tools get the basic job done, but the results often look rough and unpolished.
If you want to take your screenshots to the next level and make them look professionally designed with minimal effort, you need a tool like Xnapper.
Xnapper is a powerful, intuitive screenshot app for Mac that allows you to capture beautiful, annotated screenshots in just seconds.
In this guide, we'll walk through how to use Xnapper to quickly snap a screenshot, annotate it, and share it out, so you can communicate visually with style and clarity. Let's get started!

Step 1: Download and Install Xnapper

First things first - head over to the Xnapper website at and hit the big "Download" button to grab the latest version of the app.

Step 2: Capture a Screenshot

Now that you have Xnapper up and running, you're ready to capture a screenshot. Xnapper offers a few different ways to do this:
  1. Use the global keyboard shortcut: By default, you can press Control+Option+Command+4 to capture a customizable rectangular region of your screen. If you want to change this shortcut, open Xnapper Preferences.
  1. Capture a specific window: Press Control+Option+Command+4 then hit the Spacebar. Your cursor will turn into a camera icon - hover over the window you want to capture and click to screenshot just that window.
  1. Open an image from clipboard or file: If you already have an image copied to your clipboard or saved as a file, you can import it into Xnapper to annotate it. Just click the Xnapper menu bar icon and choose "Paste from Clipboard" or "Open from File".
Whichever method you choose, Xnapper will snap your screenshot and open it in the annotation window, where the real magic happens.

Step 3: Annotate Your Screenshot

This is where Xnapper really shines.
As soon as you capture a screenshot, Xnapper automatically enhances it to look amazing with zero effort on your part.
It detects the main content of your screenshot and perfectly balances it on a background, with subtle rounded corners and a drop shadow.
But Xnapper doesn't stop there - it offers a variety of powerful annotation tools to help you communicate your message:

Add Text, Arrows, and Shapes

Using the tools at the top of the Xnapper window, you can quickly add text, arrows, rectangles, and ovals to your screenshot.
This is perfect for calling out specific elements, providing instructions, or adding funny captions.
To add an annotation, simply click the relevant icon, then click and drag on your screenshot.
You can customize the colors, line width, and fonts in the right-side Appearance panel.

Redact Sensitive Information

Need to share a screenshot that contains an email address, API key, or some other private data? No problem.
Just click the Redact tool, draw a rectangle over the text you want to hide, and Xnapper will pixelate it into oblivion.
Xnapper is smart about detecting sensitive information too.
It uses macOS's built-in machine learning to locate things like credit card numbers and can redact them automatically with a single click.

Highlight Important Details

In addition to the annotation tools, Xnapper offers some handy ways to highlight key parts of your screenshot.
You can use the Blur tool to de-emphasize the background and focus attention on the important content.
Or try adding a bright background color behind your screenshot's main content using the Background panel on the right.
Xnapper's backgrounds automatically adapt to the light or dark appearance of your screenshot.

Copy Text from Screenshots

Here's a cool Xnapper feature you may not know about: you can actually select and copy text directly from your screenshots!
Just click the Text Select tool, draw a rectangle around the text you want to grab, and paste it into any other app.
This is powered by macOS's Vision framework and machine learning, so it works like magic to recognize the text in almost any image.
It's a huge time saver when you need to quote an excerpt from a screenshot.

Step 4: Share Your Screenshot

Once you've got your screenshot looking just how you want it, it's time to share it out to the world! Xnapper offers a few ways to do this:
  1. Save to Desktop (or other location): By default, Xnapper will save your screenshot as a PNG file on your Desktop when you hit the Save button. If you want to change the save location, open Xnapper Preferences.
  1. Copy to Clipboard: To quickly paste your annotated screenshot in another app, click the Copy button in the bottom-right corner. Then press Command+V to paste it wherever you need it.
  1. Drag and Drop: You can also share your screenshot by dragging it out of the Xnapper window and dropping it into an email compose window, Slack message, or any other app.
  1. Share Automatically: If you find yourself frequently sharing screenshots to the same places, you can automate the process by setting up a Share workflow in Xnapper Preferences. For example, you could configure Xnapper to automatically upload each screenshot to a Dropbox folder and copy a shareable link to your clipboard.

Bonus: Customize Xnapper to Your Liking

Xnapper is infinitely customizable, so you can set it up to match your unique screenshot needs and aesthetic preferences. Here are a few key settings to play with:
  • Appearance: Choose the colors, fonts, and other visual styles for your annotations. You can even save your favorite looks as presets.
  • Shortcuts: Customize the global keyboard shortcuts for capturing screenshots and other actions. Set them to whatever feels natural to you.
  • Background: Pick your favorite background colors and gradients, or even upload your own background images. Great for matching your brand or mood.
  • Padding & Shadows: Fine-tune the spacing around your screenshot's content and the style of the window shadows. Dial in that perfect, polished look.
  • Redaction: Choose your preferred redaction style - from pixelation to solid color blocks. Protect that private info in style.
To access these settings and many more, click the Xnapper menu bar icon and choose "Preferences", or click the gear icon in the bottom-left of the annotation window.
