핵심 아키텍처 및 수학 공식
PDF Document = Root Catalog ➔ Page Tree ➔ [Page Object (Image Stream) * N]
A PDF is a container. The converter takes the raw binary stream of your JPEG, wraps it in a PDF object dictionary, and assigns it to a newly generated Page object with specific physical dimensions.
모범 사례 및 필수 지침
- Optimize Images First: If you combine ten 15MB 4K photos into a PDF, the resulting PDF will be over 150MB and impossible to email. Always compress and downscale your images before encapsulating them.
- Standardize Margins: When submitting legal documents, set a consistent white margin (e.g., 0.5 inches) around the image to ensure no data is cut off by standard office printers.
- Use JPEG for Scans: If you are converting scanned documents, save the scans as JPEGs, not PNGs. A multi page PNG-to-PDF file will be exponentially larger than a JPEG-to-PDF file.
자주 묻는 질문 (FAQ)
Can I extract the images back out later?
Yes. Because the PDF simply acts as a container, the original raster image stream is intact inside the file. Standard PDF extraction tools can pull the exact image back out.
Will the PDF have searchable text?
No. This tool simply places a photo onto a PDF page. To make the text searchable, the PDF must undergo Optical Character Recognition (OCR).
Why is the page size huge?
PDFs use physical measurements (points, inches, mm). If you insert a massive 4000px image without scaling it to a standard page size (like A4 or Letter), the PDF will render as a massive digital billboard.
