What is Image to PDF Conversion?

Image to PDF conversion is the process of converting image files (JPG, PNG) into PDF format. This is especially useful when you want to combine multiple images into a single PDF document, or when you need to share images in a more professional format.

Our free image to PDF converter allows you to convert images to PDF without uploading them to any server. All processing happens directly in your web browser using advanced JavaScript libraries, ensuring your sensitive images remain completely private and secure.

Advanced Settings and Best Practices

Page Size & Orientation

Choose A4/Letter or auto-fit to image. Use landscape for wide photos; portrait for documents.

Fit Strategy

Cover (fills page, may crop), Contain (no crop, may add margins), or Exact (no scale).

Image Quality & DPI

Control JPEG quality for size vs clarity. 150–300 DPI is ideal for print; 96–150 DPI for screen.

Reorder & Margins

Drag to reorder images and set margins to avoid edge clipping. Add headers/footers if needed.

Technical Notes

PDFDonkey embeds images into PDF pages entirely in your browser via pdf-lib. Nothing is uploaded.

Large images are downscaled client-side when quality presets are used.
PNG preserves transparency; JPG produces smaller files without alpha.
Processing time scales with image count and resolution.

Accessibility and Performance

Keyboard-friendly reorder and delete controls.
Lazy-loaded thumbnails for many images.
Optimized bundles with Vite for fast interactions.
