If you cropped too tightly in the lightingshot editor, use 撤销 (Undo) before reloading the page or importing another image. An applied crop can be reversed within the current editing session. If you added marks afterward, undo those newer edits first until you reach the crop. This recovery uses the editor's history; it cannot reveal pixels missing from an independently imported cropped file.
Recover the crop in the current session
- Keep the editor open. Do not refresh, navigate away, or import the same file again as a first response. A successful import replaces the current image and clears its undo and redo history.
- Close any open text or export dialog. Inspect the canvas so you can see what changes after each action.
- Select 撤销 (Undo) once. If cropping was the last edit, the earlier image dimensions and pre-crop annotations return. If a later arrow or label disappears instead, you have stepped back one newer edit.
- Continue one step at a time. Stop when the missing image area returns. Inspect the boundaries rather than repeatedly pressing Undo without checking.
- Choose the corrected frame. If you want a different crop, select 裁剪 (Crop), drag a new rectangle, and release. Keep the context that was accidentally removed.
- Export a separate copy. Use a distinct filename and open the saved result to verify its edges and annotations.
You can also use Ctrl+Z on Windows or Command+Z on macOS when focus is outside an input, text area, or select control. In an input, the key may edit text instead of changing the canvas. The toolbar button makes the intended action clearer when you are unsure where keyboard focus is.
What happens to annotations around a crop?
A crop renders the visible image, including existing marks, into a smaller base picture. Undoing that crop restores the previous base image and the annotation history that existed before cropping. You do not need to import the original merely because an older arrow looks like part of the cropped picture.
Consider an illustrative sequence: import a dashboard, draw an arrow, crop the chart, then add a text label. The first Undo removes the new label. The second Undo restores the larger dashboard with the earlier arrow. This describes the current history behavior; it is not a claim that we recovered a user's lost file.
If you undo once more, you step back through the pre-crop annotation history. Stop at the state you need. Undoing a crop does not automatically relocate later annotations onto the restored image. Later edits must be reapplied if you decide to make a different crop. The annotation guide explains how to add those marks.
Use Redo before making a new edit
重做 (Redo) can restore the crop and subsequent edits you just undid, one step at a time, while that history remains available. The keyboard equivalent is Ctrl+Shift+Z or Command+Shift+Z with focus outside the form controls. Inspect after each step so you do not restore more than intended.
A new committed edit clears the redo branch. For example, after undoing a crop, drawing a new arrow or applying a different crop begins a new sequence. Do not expect Redo to recover the abandoned crop afterward. If you only wanted to compare the two states, use Undo and Redo before drawing anything new.
If you already exported, reloaded, or reimported
Exporting a file does not by itself clear the still-open editor's history. You can return to that same canvas and undo while the session remains available. The downloaded PNG, JPEG, or image PDF, however, is an output copy rather than a saved editable project with Lightingshot history.
If the page was reloaded or a new image was successfully imported, the previous in-memory edits are unavailable through Undo. Find the original screenshot you kept separately and prepare the crop again. Importing an already cropped export cannot restore the removed outer area. There is no project-recovery or automatic session-restore control in this release.
Check privacy again after recovery
Restoring a wider image can bring back private details outside the crop. Review the whole restored canvas before exporting, including any covers that changed while stepping through history. Use the privacy-cover checklist before sharing.
For a new attempt, the regular crop guide helps you choose the boundaries. Keep the original and the inspected output as separate files so a future correction does not depend entirely on an open editing tab.
