PicPeek · macOS / Windows desktop

Browse fast, compare many, pin references.

A cross-platform desktop image workspace. Open a folder, view many images on one screen, compare versions and folders, and pin reference images above other windows. Agents can also find, open, compare, and pin images when needed. Images are processed on your device only, never uploaded.

PicPeek immersive fullscreen browsing with autoplay

When reviewing design drafts or filtering AI-generated images, details make or break the call. Double-click to enter fullscreen: the image fills your entire screen, all interface elements fade away, and you can zoom into every pixel. Flip through manually or set an autoplay interval, staying focused without interruption.

  • Interface fades away
  • Manual or autoplay
  • Zoom into details

Fastest way to pick one from dozens of AI outputs: review them in fullscreen.

PicPeek pin anywhere: images pinned on the desktop

Tired of switching windows back and forth to check reference images while coding, designing, or filling forms? Any image can be pinned on top of everything, floating above all your windows. Make it translucent, resize it, drag it anywhere, and pin several at once. It stays put no matter which window you switch to.

  • Floats above windows
  • Adjustable opacity
  • Pin several at once

Pin a wireframe beside your editor while you code, or keep a family photo next to your spreadsheet for company.

PicPeek image comparison: side-by-side, difference, and overlay views

What changed in the new UI screenshot? What's different between two design versions? Put two images together and view them side by side, overlaid, or with the differences highlighted for you. Hover anywhere and read the exact pixel color, so even a single changed pixel shows up.

  • Side-by-side / overlay / diff
  • Per-pixel color values
  • Two-folder compare

Screenshot regression or design proofreading: differences are highlighted, no need to hunt pixel by pixel.

PicPeek supports one-line Agent commands to pick from many images

Install Agent Skill and your AI assistant can drive PicPeek directly. Say what you are looking for and it finds the images and lays them out for you to pick. Everything is processed on your device, never uploaded.

  • AI assistant calls it
  • Many images on one screen
  • All on-device

"Open today's exported home page screenshot and the previous version" — the images are laid out before you finish the sentence.

Optional advanced feature. Regular browsing and comparison work without it.
