Comprehensive Overview & Technology

Compiling multiple digital images into a single PDF document is an essential task for submitting expense reports, submitting homework assignments, assembling legal portfolios, and archiving scanned identification documents. However, many free online services impose artificial limits, add intrusive watermarks, or worse, store your sensitive personal photos on third-party servers.

Our Image to PDF Combiner puts privacy and user autonomy first. By executing the entire PDF structure creation in your browser using pure JavaScript (pdf-lib), your photos, financial receipts, and personal identity documents remain strictly confined to your device.

The intuitive visual interface lets you inspect thumbnails, discard unwanted shots, reorder pages, and adjust page margins. Whether you need a formal portrait A4 document for an institutional submission or an edge-to-edge album layout, you can customize every aspect in seconds.

Under the Hood: Engine Architecture

When you upload images, the tool loads them into memory as raw ArrayBuffers. JPEG images are embedded directly into the PDF structure using pdf-lib’s native embedJpg() pipeline, which retains original compression quality without redundant re-encoding.

PNG and WebP images are normalized on a temporary canvas element and injected via embedPng(), calculating proportional bounding boxes that respect your chosen page size (A4: 595.28 x 841.89 points, US Letter: 612 x 792 points) and margin offsets.
