| 10 | 🗜️ Image Compressor | Reduce image file size with live before/after stats |
| 11 | 🔗 Merge Images | Stitch images vertically or horizontally with custom gap & color |
| 12 | 📏 PDF Resizer | Change page dimensions (A4, A3, A5, B5, Letter, Legal, Custom mm). Content scales to fit. Use this for printing on a specific paper size — not for reducing file storage size. |
| 13 | 📎 PDF Merger | Merge multiple PDFs into one — drag to reorder files. Optional: set a target output file size in KB/MB. |
| 14 | 🗜️ PDF Compressor | Reduce file storage size (KB/MB) for email, uploads & form submissions. Page dimensions stay exactly the same. Choose preset level (Screen/eBook/Printer/Prepress) or set an exact target KB/MB. |
| 15 | 📝 DOCX → PDF | Convert Word (.docx) documents to PDF — headings, paragraphs, bold/italic and lists preserved. |

Uses Mammoth.js to extract raw text content and jsPDF to generate a cleanly formatted PDF. Basic heading detection is applied (short all-caps lines are bolded). Complex DOCX formatting like tables, images, and custom styles is simplified in the output.
The compressor uses a binary search algorithm to hit your requested KB/MB target. It renders each page as JPEG at varying quality levels (up to 10 iterations) until within ~8% of your target. Page dimensions are never changed.
When resizing to a new page size, content is scaled proportionally and centered on the new page. Use "Scale content to fit" checkbox (on by default) to ensure nothing is cropped.
