Gumnut shows the saved edit when you browse, while keeping the untouched upload available to download or restore. The photo stays in the same albums and keeps its metadata and person associations. ## Edit in the web app You need the Owner or Collaborator role in the photo's library. Open a photo in the [web app](https://app.gumnut.ai), choose **Edit**, then crop, rotate, or mirror it and choose **Save**. The editor works in desktop and mobile browsers. Saved edits appear in the timeline and album covers. Gumnut web editor with a crop box, orientation controls, crop ratios, and Save button You can reopen a compatible saved edit to adjust it. The editor applies your adjustments from the original rather than repeatedly cropping an already cropped file. Videos, animated images, and externally produced versions cannot be edited with the built-in geometric editor; some images may also be unavailable while processing or because the browser cannot decode them. ## What Gumnut keeps An asset is one photo or video record. A version is a stored file belonging to that record. Gumnut keeps the **original and at most one edited version**. Saving another edit replaces the previous edited version; it does not build a history of every save. Replacing an edit or reverting to the original permanently removes the previous edited version. Download it first if you want to keep it separately. On an edited photo, the download control lets you choose the current version or the original. To restore the untouched upload, choose **Revert to original** from the photo's overflow menu and confirm. Face boxes are hidden while an edited version is current, because their coordinates describe the original. Existing person associations stay attached to the photo; restoring the original brings its boxes back. ## Other editing tools Immich clients and external applications can save edits as versions through the API. External producers can upload a finished image, but Gumnut's editor cannot reopen arbitrary external edits as adjustable crops or rotations. Both retained versions count toward storage. An [AI assistant](/guides/product/ai-assistants) can also transform a photo with its own image tools and save the result as a separate asset. That workflow is different from replacing the photo's edited version. See [Versioning and Editing Assets](/guides/apis/asset-versioning) for the API contract, supported editing recipes, and version conflict handling.
