Quality and File Size Tips

  • For web sharing / email: Use 80% quality for the smallest PDF file.
  • For printing: Use 95% quality for high-fidelity output.
  • For archiving: Use 85% quality (default) for the best balance.
  • Image resolution matters more than the PDF quality setting. Higher resolution source images produce sharper PDFs.
  • “Fit to Image” page size avoids scaling and produces the sharpest output, but page sizes may vary.

JPG to PDF vs Other Conversion Paths

JPG → PDF: Best for photos. JPG images are already compressed, so the PDF file size stays manageable. Ideal for photo albums, product images, and reports with photographs.

PNG → PDF: Best for graphics with sharp edges, text, and flat colors. PNG images produce crisper results but larger PDF files. If your PNGs are photos, consider converting to JPG first for a smaller PDF.

Need to compress first? Use our JPEG compressor or image resizer before creating your PDF to minimize the final file size.

Common Questions

Can I merge multiple images into one PDF? Yes — that's the primary purpose of this tool. Upload up to 20 images and they'll be combined into a single PDF document, one image per page. Drag thumbnails to arrange the page order.

Will the image quality change? This depends on the quality setting. At 85% (default), images are virtually identical to the originals. The quality slider controls JPEG compression within the PDF — lower quality means smaller file size.

What page sizes are supported? A4 (global standard), US Letter, A3, and Fit to Image (page matches each image's dimensions). The Auto orientation mode automatically matches each page to its image — landscape images get landscape pages.

Can I reorder pages? Yes — drag and drop the image thumbnails to rearrange them in any order before generating the PDF. The page numbers update automatically as you reorder.
