Converting PNGs to PDFs is the process of changing a raster (bitmap) image format to a vector (path-based) document format. PDFs are known for their cross-platform compatibility and support for embedding fonts, hyperlinks, and other interactive elements.
This conversion is valuable for preserving image quality, especially when resizing or printing. It allows for lossless compression, retaining the original image’s sharpness and detail. A notable historical development was the introduction of Adobe Acrobat in 1993, which popularized PDFs and established them as a widely adopted document format.
