PDF Page Size Geometry & JPEG Stream Embedding Architecture
Unlike server tools that decode and re-compress your JPGs, JoyTools embeds the original baseline/progressive DCT JPEG byte stream directly into the PDF XObject.
Scale = MIN((PageWidth − 2×Margin) ÷ ImgWidth, (PageHeight − 2×Margin) ÷ ImgHeight)Ensures every JPG photo is centered and scaled to fit within the printable area without stretching or cropping.
| Page Size Preset | Dimensions (mm / in) | PDF Coordinate Points | Best For |
|---|---|---|---|
| ISO A4 (Default) | 210 × 297 mm | 595.28 × 841.89 pt | Contracts, invoices, CVs & international printing |
| US Letter | 8.5 × 11.0 in | 612.00 × 792.00 pt | North American forms, tax filings & legal docs |
| Fit Image | Matches source JPG | 1 px = 1 pt (Exact Ratio) | Portfolios, photography books & full-bleed slides |
