1, use the "cutting tool" to cut.
First cut off the left side, and then enter a value in Right Side. This can be used not only for single pages, but also for batches. Enter a starting and ending page number in Page Range, or select All Pages. Finally, click "Confirm".
2. After returning to the document, you can see the cropped left page, and then use the Extract Page tool to extract the page.
You can make a selection in the dialog box again. If the red box is selected, the save path window will appear, and you can follow the steps to save.
3. After saving, use the shortcut key combination "ctrl+z" to restore the document to its original appearance before cutting. At this time, repeat the above steps of 1~2 to cut out the page on the right.
Cut the right page and don't go back. Just use the Insert Page tool to insert the left page you just saved.
As for your page order, you can drag and drop pages to manage and sort.
