Free Online CID to AVIF Converter

This is a format for presenting fonts in PDF files that was initially conceived to store symbols in the Japanese and Chinese languages because it had a 16-bit structure and allowed for more precise adjustment. CID expands the the potential for PostScript by supporting languages that do not have a left-to-right orientation, and by supporting even a vertical mode of orientation.

AVIF is the youngest, but most efficient and advanced codec for image compression. AVIF file size is 10 times smaller than JPEG with the same image quality. AVIF supports not only Standard Dynamic Range (SDR) images but also High Dynamic Range (HDR) and Wide Color Gamut (WCG). It can store both image items and image sequences. AVIF is a HEIF conformant format. Netflix has published the first AVIF image in 2018, but still only a few software support it.
