About JPG to PDF
Combine multiple JPG, JPEG, and camera photos into a clean, standardized, and universally shareable PDF document in seconds. Our in-browser JPG to PDF converter embeds JPEG image bitstreams directly into standard PDF Image XObjects using native DCTDecode filters. This preserves 100% of your original photo quality with zero re-encoding loss, while enforcing uniform page dimensions and clean margins.

Deep-Dive Technical Explanation
A common misconception is that converting JPG to PDF compresses your images a second time. In reality, the PDF specification natively supports the raw JPEG bitstream via the `/DCTDecode` stream filter. When our client-side engine compiles your photos into a PDF, it wraps each image directly inside an indirect object dictionary (`/Subtype /Image /Filter /DCTDecode /Width w /Height h /ColorSpace /DeviceRGB /BitsPerComponent 8`) and maps it to a page coordinate system (`/MediaBox`). This produces a pristine PDF with zero quality degradation and lightning-fast execution.
Package receipts, handwritten notes, portfolios, and scanned documents into professional PDFs in seconds. No cloud uploads, no watermarks, and zero file size caps.
