FAQ
Why is the Crop button grayed out?
- Make sure the current PDF file is editable.
- Click the image to confirm that it is selected.
- Check whether you are in the image editing area.
- If the button is still unavailable, confirm that your account has PDF editing access.
Can I undo a crop after applying it?
- After cropping, press Ctrl+Z if you want to restore the previous state.
- Check whether the image returns to its earlier appearance.
- If you completed several actions, continue undoing until you reach the state you want.
Does cropping change the original image size?
- Cropping mainly changes the visible area of the image.
- The original image content is not directly rewritten just because the visible area changes.
- After you save the document, the page shows the cropped result.
Why might I be unable to edit an image directly in a scanned PDF?
- Content in a scanned PDF may be a full-page image instead of a separately selectable image object.
- First try to identify whether the page contains editable objects.
- If you cannot select the image directly, run OCR first and then continue editing.
