ACD Systems is committed to releasing regular updates to support RAW files from new camera models, as they become available. View the complete list of supported RAW formats.

New Features

  • AI Image Generation — Start from a text prompt, choose a preset visual effect, or bring in reference images for character, style, and composition.
  • Generative Fill — Fill in the missing details of a photo as if they were always there.
  • Generative Edit — Describe a change in your own words, or use reference images to guide the look.
  • AI Remove — Erase unwanted objects without a trace.
  • Auto-Stack — Point ACDSee at a folder and let it find the groups for you. Automatically stack by GPS location, capture time, image similarity, or any combination of the three.
  • Custom Stacking — Group files into stacks by your own reasoning.
  • AI Reverse Image Search — As you browse your folders, AI Image Similarity quietly compares your photos by how they look — no tagging, no keywords, no setup. Then select any image and let AI Reverse Image Search find every visually related shot.
  • Group By AI Image Similarity — Group By now includes Group By AI Image Similarity, clustering visually related photos.
  • Reject Tag — Mark blinks, blurs, and duds with the new Reject Tag as you review.
  • Previews – In Edit Mode, see what a preset or blending mode will do before you apply it. Just hover over it in the list.
