You can now add borders to images, videos, and GIFs.

What’s new and why it matters

Before, adding a border meant building a workaround: placing a shape behind your media, lining it up perfectly, and then managing multiple layers any time you resized or animated those elements.

Now, borders are built-in:

  • Add a border directly to an image, video, or GIF
  • Choose how it sits: inside, outside, or centered
  • Combine borders with rounded corners

A few ways you might use it:

  • Frame screenshots and screen recordings in product walkthroughs
  • Add clean padding around media elements
  • Create layouts and custom templates that are better aligned with your brand
