About PNG to PDF conversion
PNG was released in 1996, uses DEFLATE lossless compression, and is a standard image format for screenshots and design deliverables. PDF was released by Adobe in 1993, became the open ISO 32000 standard in 2008, and is a general standard format for document exchange. This conversion需求 meets the need of users to integrate single or multiple PNG images into a distributable document.
PNG to PDF conversion uses embedding processing, original PNG image data is not secondary compressed. The original 8-bit alpha channel and 48-bit color depth of PNG can be fully preserved, EXIF metadata is retained intact with the image data. The converted file size is larger than the sum of the original PNG files.
This conversion is suitable for workflows that require integrating multiple design PNGs into a standard document for delivery, and saving web screenshots as cross-platform openable documents. All major operating systems and browsers can directly open the output PDF file.
