How JPG images are embedded into a PDF

This tool builds the PDF using pdf-lib, a JavaScript library that constructs the PDF binary format directly in the browser. PDF is a container format — images are not re-encoded inside it; they are stored as embedded objects. For JPG images specifically, pdf-lib embeds the raw JPEG data stream as-is using the PDF DCTDecode filter, which is the standard way PDF files reference JPEG-compressed images.

Because the JPEG data is embedded without re-compression, there is no quality loss during conversion. The file size of the resulting PDF will be close to the combined size of your original JPG files plus a small overhead for the PDF structure and metadata.

Why combine photos into a PDF?

A PDF is a single, universally readable file that preserves layout and page order — making it the standard format for sharing multi-page documents. Common use cases include: submitting scanned forms or receipts as a single attachment, packaging product photos for a client, combining handwritten notes from multiple pages, and archiving photos from an event in a fixed-order document.

PDF is also the expected format for many professional and government submission systems that require documents rather than image files. A JPG to PDF converter bridges the gap when you have images but need a document.

Getting the best results: image size, orientation, and order

Each JPG is fitted to an A4 page (595 × 842 PDF points, equivalent to 8.27 × 11.69 inches) while maintaining its aspect ratio. Wide landscape photos will be centred on a portrait A4 page with white margins above and below — the image is scaled to fill the width. Tall portrait images fill the full page height.

For the cleanest result, crop and rotate your JPGs before upload. If your images came from a phone camera in portrait orientation, check that they display upright in a photo viewer before uploading — JPEG EXIF rotation tags may not be honoured by all PDF viewers, which can cause images to appear sideways in the PDF.

If page order matters, arrange images before clicking Convert. The up and down arrows let you reorder without re-uploading, but verifying the thumbnail order before conversion avoids having to redo the process.
