How to use and verify
Text copied from PDF documents often contains line breaks caused by the page width. Preserve paragraphs joins lines inside each block with a space and keeps blank-line boundaries as two line breaks. Windows and other line-ending conventions are first normalized.
Join all also removes paragraph boundaries. Trim lines leaves every line boundary in place while removing leading and trailing whitespace. Choose a space or no separator when joining. Korean and English prose usually needs a space; if a word was split in the middle, review and edit the result manually.
This is a deterministic text cleanup tool, not a language model. It cannot infer separate paragraphs without blank lines. Lists, code, poetry and addresses may rely on line boundaries, so use Trim lines for those inputs. Hyphens and punctuation are not removed automatically. The input remains available for comparison. Copy the separate output or save a UTF-8 text file. Always check headings, numbered items and the beginning of each paragraph before using the cleaned text elsewhere.
