25 50 44 46The Portable Document Format (PDF) is a ubiquitous digital paper standard designed to present documents consistently independent of application software, hardware, and operating systems.
89 50 4E 47 0D 0A 1A 0APortable Network Graphics (PNG) is an unencumbered raster graphics file format that supports lossless data compression, indexed colors, and variable alpha channel transparency.
FF D8 FFJPEG is the most widely adopted lossy compression standard for digital photography and web imagery, exploiting the human eye's higher sensitivity to luminance over chrominance.
52 49 46 46WebP is a modern image format developed by Google that provides superior lossless and lossy compression for web images, supporting both alpha transparency and animated frames.
66 74 79 70 61 76 69 66AVIF is a next-generation open image format derived from the AV1 video codec, delivering cutting-edge compression efficiency, high dynamic range (HDR), and wide color gamuts.

50 4B 03 04DOCX is a zipped, XML-based file format developed by Microsoft for word processing documents, standardizing Word documents under the Office Open XML specification.
50 4B 03 04ZIP is an archive file format that supports lossless data compression, allowing multiple files and directories to be packaged into a single transportable container.
47 49 46 38The Graphics Interchange Format (GIF) is an 8-bit palette-based raster image format developed by CompuServe, celebrated worldwide for popularizing short looping animations on the early web.
7B or 5BJavaScript Object Notation (JSON) is a lightweight, human-readable text format for data interchange, completely language-independent and universally used for web APIs.
Plain TextComma-Separated Values (CSV) is a ubiquitous plain-text format for tabular data, where each line represents a data record and fields are separated by delimiter characters.
3C 3F 78 6DExtensible Markup Language (XML) is a versatile markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
