Free online CR2 to JPG converter lets you convert multiple CR2 files at once. You can choose output file size or quality you want to produce better JPG files. Optionally, you can change to image resolution when converting CR2 files to JPG.
It is a free tool to convert CR2 image format file to JPG/JPEG format. We don't put watermark and allow unlimited convertions for free.
We provide a simple way to transform your image files from one format to another.
The Canon RAW version 2 (cr2) format is a RAW format created by Canon for storing digital images. This does not contain a ready to view picture like a JPG or PNG file, it is used to store information directly coming from the sensor. You can choose to store your pictures in RAW format which gives you the benefit of being able to do a lot of post processing on the file, if you tried to do this with JPEG, this would be difficult and would likely result in a quality loss.
RAW files are the best quality to size ratio that a photograph can be stored in, primarily because each colour is recorded in either 12 or 14 bits and a lossless compression is used. The CR2 takes over from Canon's previous format - CRW and is used by the Canon 350D, 1D, G9 and 20D models.
JPG's are often used for web sites and email as they are generally smaller file sizes as they are lossy meaning that some image quality is lost when the JPG is compressed and saved. The resultant 'lossy' file means that quality can never be recovered. The JPG format is often used in digital camera memory cards. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth.
JPG is a popular graphic format, which is characterized by a high degree of compression, which leads to a decrease in image quality. It uses the technology of encoding of smooth color renditions, providing the ability to reduce the amount of data frequently during the recording of the image. Because of the small size it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPG algorithm is optimally suitable for compressing photographs and pictures, in which realistic scenes with little contrast of colors are present. It is not recommended to use this format for compression of drawings and various kinds of graphics, since a strong contrast between a number of closely located pixels provokes the appearance of visible artifacts.
JPG is a graphical file format for editing still images, it offers a symmetrical compression technique which is processor intensive and time consiming in both compression and decompression. JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. Compression rates of 10:1 or 20:1 yield little degradation in image quality.
The procedure for compressing the digital images in JPG format is carried out in several stages. First, the photo is transformed into a color space YCbCr, then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial.
