📋 Known Limitations

• PDF → DOC text extraction is best-effort. Scanned PDFs (image-based) may return no text.
• DOCX → PDF uses plain text rendering — formatting, fonts, and images are not preserved.
• Page extraction from DOCX splits by ~3000 characters per page, not by document-defined page breaks.
• Files above 50 MB are rejected to protect browser performance.
