The .jpg filename extension refers to digital photography files or digital images that are associated with the JPEG file format specification. The joint photographic experts group, or JPEG for short, is a file format from the 'lossy image' class of image formats. Many devices including smartphones with inbuilt cameras and professional digital SLR cameras support the JPEG/Exif file format natively. Such support allow images captured on these devices to be stored directly into the jpg format without conversion. Efforts towards standardization of the JPEG format first begun in 1992 with ISO/IEC 10918-1:1994
The Picture Exchange file format, shortened PCX, with the .pcx filename extension is an image file format developed by ZSoft Corporation. It was initially released in 1985 as a lossless bitmap image format and for a time was the default file format for PC paintbrush. The format is now largely superseded by other formats given the target platforms for the software associated with the format are no longer in production, i.e. MS DOS and Windows 1.0.
FreeFileConvert uses tuned encoding for JPG to PCX conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload JPG files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized PCX results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent PCX audio with dependable progress tracking.
Being a 'lossy image' file format, digital image files saved as .jpg files use encoding algorithms that make inexact approximations of the photographic data to save on storage space during compression. This allows for relatively small files that are suited for delivery over networks or in low bandwidth scenarios. The jpg file format is flexible in that it accommodates a tradeoff between the size of the file and the image quality during compression. Image compression may leave noticeable artifacts in the produced image. The maximum resolution supported by the JPEG format is 4 Giga pixels.
Later iterations of the format supported 24bit color palette, upgrading from the original 2 to 4 colors. Byte ordering used by the format is little endian ordering with three blocks; a 128 byte header, image data and an optional 256 color palette. Image data is stored in an orthoganal arrangement of scan lines ordered from the top to the bottom. Files can eiher be compressed using the simple RLE (Run Length Encoding) algorithm or uncompressed.
