+
+| # | Tool | Category | Complexity | Dependencies | Notes |
+|---|---|---|---|---|---|
+| 11 | **PDF to PDF/A** | PDF | Medium | Ghostscript (exists) | Archival format conversion. |
+| 12 | **Flatten PDF** | PDF | Low | PyPDF2 (exists) | Remove form fields / annotations → flat page. |
+| 13 | **Crop PDF** | PDF | Medium | PyPDF2 (exists) | Crop margins / adjust page boundaries. |
+| 14 | **Compare PDFs** | PDF | High | `diff-match-patch` + PyPDF2 | Side-by-side visual diff of two documents. |
+| 15 | **QR Code Generator** | Utility | Low | `qrcode` + Pillow | Text/URL → QR image. Client-side possible but backend for API. |
+| 16 | **Barcode Generator** | Utility | Low | `python-barcode` | Generate Code128, EAN, UPC barcodes. |

+### Recommended Next Sprint
+
+**Highest ROI — 6 tools to reach 80%+ parity with SmallPDF/iLovePDF:**
+
+1. Compress Image (Pillow — already installed)
+2. PDF to Excel (`camelot-py`)
+3. HTML to PDF (`weasyprint`)
+4. Sign PDF (ReportLab overlay)
+5. Reorder Pages (PyPDF2 — already installed)
+6. PDF to PowerPoint (`python-pptx`)
