Does paraphrasing remove plagiarism?
No. Plagiarism is presenting someone else's ideas or work as your own, so rewording a passage without citing it changes the wording and leaves the offence exactly where it was.

The confusion comes from what plagiarism software measures. A similarity checker finds matching strings, so a thorough paraphrase lowers the score — and people reasonably conclude that a lower score means a smaller problem. It does not. The score fell because the detection method is string matching, not because the borrowing stopped.
Academic definitions of plagiarism cover ideas, structure, data and argument as well as wording. Following a source's reasoning paragraph by paragraph in your own words, with no citation, is a textbook example — and it is harder to defend than a quoted sentence, because it looks like an attempt to conceal rather than an oversight.
The fix is not more rewording. It is a citation. A paraphrase with a source attached is normal, correct academic practice and always has been; the same paraphrase without one is the problem, at any level of rewriting.
This matters more now because paraphrasing tools make heavy rewording effortless. The tool changes how much work concealment takes. It does not change what the rule is.
When this answer changes
Common knowledge does not need a citation — facts widely known in your field and available in many general sources. The boundary is genuinely fuzzy and discipline-specific, and when in doubt the cost of an unnecessary citation is nil.
Your own earlier work is a separate case. Reusing it without disclosure is self-plagiarism under many institutional policies, and paraphrasing does not resolve that either.

- Why the score drops anyway — What string matching can and cannot see.
- Whether paraphrasing defeats AI detection — A different question with a different answer, and one with published evidence behind it.
- Paraphraser or rewriter? — Decided by what you paste in, and only one of the two raises a citation question.
