1. Tool Introduction
This free online PDF text extractor runs entirely in your browser, no registration or installation required. It quickly extracts text from PDF documents with smart layout optimization, supports watermark filtering by keywords and removes short invalid lines like headers and footers. Extracted text can be copied directly or exported as TXT/Word documents. All data is processed locally without uploading to any server, fully protecting your privacy.
2. Application Scenarios

Office work: Extract and edit text from PDF contracts and reports.
Content organization: Extract text from standard PDFs (not scanned image PDFs).
Data cleaning: Filter watermarks, headers and footers in batches for clean text.
Document archiving: Export PDF text to Word or TXT for long-term storage.
3. Operation Steps
Step 1: Upload PDF File
Click "Select PDF File" and choose a document from your computer. We recommend keeping files under 50MB for smoother processing. After uploading, the file name, size and total pages will be displayed.
Step 2: Set Page Range (Optional)
Enter the start and end pages if you only need partial content; leave blank to extract all pages by default.
Step 3: Configure Filter Options (Optional)
Keep original format: Preserve original line breaks and spaces; disable to auto-optimize layout.
Delete lines by keywords: Enable and enter keywords (separated by commas) to remove lines with watermarks or confidential labels.
Remove short lines: Enable and set a character threshold to delete short lines like headers, footers and edge watermarks.
Step 4: Start Extraction
Click "Start Extraction". The tool will parse text page by page and show progress. Please wait if processing a large PDF.

7. Tips
Use TXT for long-term storage (small size, high compatibility).
For heavy watermarks: use short line filter first, then keyword filter.
For double-column PDFs, enable "Keep original format" and adjust manually if text order is messy.
