PDF Character Counter
A simple and reliable PDF character counting tool that extracts text from PDF documents and counts only the actual content.
Unlike many basic PDF counters, this tool automatically detects and removes:
- Page numbers
- Repeated headers
- Repeated footers
- Running chapter headers
This makes it useful for academic papers, theses, reports, assignments, and other documents where administrative text should not be included in the final character count.
Features
✅ Accurate PDF text extraction
✅ Automatic page number removal
✅ Automatic header detection
✅ Automatic footer detection
✅ Running chapter header detection
✅ Per-page character statistics
✅ Optional page exclusion
✅ Detailed diagnostics showing removed content
How It Works
The application processes PDFs in six steps:
- Extract all text blocks from every page.
- Detect recurring headers and footers based on position and repetition.
- Identify page numbers using pattern matching.
- Detect running chapter headers.
- Remove non-content elements.
- Count characters in the remaining text.
Only the cleaned content is included in the final count.
What Gets Removed
Page Numbers
Examples:
Page 12
12
12 / 120
12 of 120
Side 12
12 af 120
Running Headers
Examples:
2.1 Methods 12
4.3 Results iv
Repeated Headers and Footers
Text that appears on multiple pages in the top or bottom regions of the document is automatically detected and excluded.
Output
The tool returns:
- Total character count
- Character count per page
- Included text
- Detected headers
- Detected footers
- Detected running headers
- Detected page numbers
- Log of removed elements
Use Cases
- Academic assignments
- University theses
- Research papers
- Government reports
- Technical documentation
- Publication word/character limit verification
Technology
Built with:
- Python
- PyMuPDF (fitz)
- Regular Expressions
- Hugging Face Spaces
Limitations
- Scanned PDFs without embedded text require OCR before processing.
- Very unusual document layouts may affect automatic header/footer detection.
- Character counts are based on extracted text and may differ slightly from counts generated by word processors.
