Calculation Methodology & Formula
Encodes raw image raster bytes into native PDF XObject Image streams, creating standard conforming PDF pages formatted with user-selected geometric dimensions and margins.
\text{PDFPage} = \text{EmbedImage}(\text{RasterBytes}, \text{Dimensions}, \text{DPI})Worked Example: Document Receipt / Photo Portfolio Export
Combine 4 scanned receipts into a single A4 PDF document.
images:4 JPG files (total 3.4 MB)
page Size:A4 (210 × 297 mm)
margin:Standard (36 pt / 0.5 in)
Expected Outputreceipts-combined.pdf (4 pages, 2.8 MB)
Embeds each receipt onto its own centered A4 page maintaining aspect ratio and text sharpness.
Technical Constraints & Limitations
- WebP images are automatically rasterized to PNG in the browser canvas before embedding into the PDF document stream.
- Very high resolution photos (over 40 Megapixels each) may consume substantial browser memory during conversion.
Frequently Asked Questions
Which image formats are supported?
You can upload JPG, JPEG, PNG, and WebP images. All formats are processed directly in your browser without quality degradation.
What is the "Fit to Image" page size option?
"Fit to Image" sets the dimensions of each PDF page to match the exact pixel aspect ratio of the respective image, eliminating white margins entirely.
Are my private photos or documents uploaded to any server?
No. Never. The entire conversion process takes place locally inside your browser using pdf-lib and HTML5 canvas APIs. No photos or data are ever transmitted.
