No, editing and proofreading are two distinct processes. While they often go hand in hand in terms of revising documents or texts, they are separate activities in terms of their goals and purposes.
Proofreading is focused on accuracy and getting all the details right. It involves making sure no spelling or grammar mistakes exist, that the document is in the right tone, style and formatting, and that the document complies with all relevant standards such as content regulations or house style. It is more a matter of checking for errors than of making changes.
Editing, on the other hand, is more about improving the overall quality of the document. Whereas proofreading is focused on accuracy, editing is focused on clarity, structure, argument and readability. It involves making changes to ensure that the document is as clear, effective, and readable as possible. It includes restructuring, rewriting, and adding or removing language as needed. Editing can also involve fact-checking and verifying the accuracy of the information in the document.
In sum, proofreading is checking for errors and mistakes, while editing is making changes to improve the quality of the document. For further reading on this topic, please refer to this article:
