How High-Resolution PDF to Image Conversion Works
PDF documents store graphics, typography, and vectors in a resolution-independent 72 point-per-inch coordinate grid. Converting them into sharp raster images requires calculating the precise pixel scaling factor and rendering via the browser's HTML5 Canvas.
HTML5 Canvas Engine
Using Mozilla's WebAssembly and JavaScript vector rasterization engine, each glyph and path is rendered natively into an off-screen HTML5 Canvas with sub-pixel precision.
Zero Server Uploads
Your PDF never leaves your computer. All processing occurs in local memory. Confidential financial audits, legal documents, and personal records remain 100% private.
Precision DPI Scaling
Standard 72 DPI yields 595 × 842 px pages. At 300 DPI (~4.17x scale), an A4 page produces 2480 × 3508 pixels, ensuring razor-sharp typography for OCR, printing, and publishing.
DPI Resolution & Output Dimensions Matrix (A4 Standard)
| DPI Setting | Scale Factor | Output Resolution (A4) | Typical Use Case | Typical Size (PNG) |
|---|---|---|---|---|
| 72 DPI | 1.0x | 595 × 842 px | Quick thumbnails, low-bandwidth web preview | ~80 - 180 KB |
| 150 DPI | ~2.08x | 1240 × 1754 px | Retina screens, emails, presentation slides | ~300 - 700 KB |
| 300 DPI (Recommended) | ~4.17x | 2480 × 3508 px | Professional print, publishing, archival, OCR text extraction | ~1.2 - 2.8 MB |
| 600 DPI | ~8.33x | 4960 × 7016 px | CAD schematics, circuit diagrams, ultra-fine typography | ~4.5 - 12 MB |
