HEIF (High Efficiency Image File Format) is a modern container format that stores images encoded with the HEVC (H.265) codec. It delivers significantly smaller file sizes than JPEG while maintaining superior image quality.
PDF (Portable Document Format) is a file format developed by Adobe to present documents independently of application software, hardware, and operating systems. It preserves the exact layout, fonts, and formatting of any document.

No, converting HEIF to PDF does not cause additional quality loss — PDF uses lossless compression. However, any artifacts already present in the original HEIF file will persist in the PDF output.
PDF files are typically 2-5x larger than equivalent HEIF files because PDF preserves all pixel data. This is expected and necessary for lossless quality.
Yes, PDF supports transparency. Alpha channel information from HEIF is preserved during conversion.
