Extract Plain Text from PDF

I will share one PDF that contains only text. Your job is to pull every word out of that file and give it back to me as clean, plain-text—no headings, no bullet points, no hidden formatting, just the raw content exactly as it appears. Accuracy matters more than speed; line breaks and paragraph spacing must mirror the source so I can drop the result straight into my workflow without further cleanup. Please return a single .txt file. I will cross-check the output against the original to confirm nothing was missed or added. If you have experience with reliable OCR or copy-paste validation tools, that will help keep errors to a minimum.
