Parses OpenXML Word document hierarchies, tables, inline images, and typography directly into formatted PDF streams without needing Microsoft Office.

2. Excel (.xlsx / .csv) to PDF Spreadsheets

Transforms workbook sheets, formula cell values, numerical data grids, and CSV matrices into clean paginated PDF landscape or portrait reports.

3. PowerPoint (.pptx) to PDF Slide Decks

Renders slide text boxes, vector shapes, layout geometries, and visual presentations into slide-by-slide PDF documentation.

4. Images & Camera Scan to PDF Image Gallery

Batch compiles JPG, PNG, and WebP captures into multi-page PDFs with auto-orientation, margin adjustments, and DPI preservation.

5. HTML / Markdown to PDF Markup Engine

Converts structured Markdown or custom styled HTML/CSS code directly into clean printable PDF documents with syntax highlighting.

💡 Pro-Tip on Security & Utility: When converting high-resolution photo scans into PDF, select 'Compress Streams' to activate FlateDecode compression, reducing final file size by up to 70% while maintaining crisp 300 DPI text.
