Your photos keep their quality
Standard JPG files are placed into the PDF byte-for-byte — they are not recompressed, so there's no quality loss. PNG files keep their transparency. Formats PDF can't hold directly (HEIC, WebP) and phone photos with a rotation flag are converted once at high quality so they appear upright.
Choosing page settings
Choose A4 for most of the world, or US Letter for North America. “Fit to image” makes each page exactly the shape of its picture — ideal for photo portfolios and on-screen reading.
- Auto orientation turns each page to match its image, so landscape photos aren't shrunk onto portrait pages
- Small margins suit scanned documents and receipts; no margin suits full-bleed photos
- Images are scaled to fit inside the margins without cropping or stretching
