ARW to J2K

Upload a ARW camera RAW file and save it as J2K. The converter uses server-side image processing for quick RAW export to common raster formats.

ARW is an uncompressed file format with a digital image of a sufficiently large size, which Sony has created and successfully uses for raw images of its own digital cameras (Sony Digital Camera Raw Image). That is, files of this format are RAW. To open them, you need to use special graphics programs. Any ARW file has a set of basic information. 1) Information from the manufacturer. This includes information about the camera model, filters, lens, sensitivity, color space, white balance, etc. 2) EXIF ​​information. Details of aperture, exposure time, flash, and more. 3) Thumbnail image. Usually about 12 MPx, color, compression. 4) Full-size image with a large color depth. Typically, 12 bits per pixel, or 4096 brightness levels. A full-sized image can be saved as information about different colors. Red, blue, green. The image is collected, and the result is a color photo. Due to this and due to the large color depth of RAW, this type of file is perfect for processing graphics. Better than jpg. The format provides the ability to save many details. It has more options for adjusting color, restoring details from shadows and reducing noise.

J2K is a raster image category file format. It is a compressed bitmap using wave compression instead of DCT compression, which is used by standard .JPEG images. The format supports 16-bit color, alpha transparency and lossless compression. The file type is JPEG 2000 Image. The J2K file format was developed by the Joint Photographic Experts Group (JPEG). J2K is an update to the JPEG format that includes original features. Say alpha channel support and lossless compression. J2K is a segment of a large package of updated JPEG extensions. They gained fame as JPEG2000. Such as J2C, JPX, JPM or JP2. The lion's share of such formats are combined with the main programs so that you can view images. However, JPEG is particularly popular. For those who specialize in photography, it is important that they have the opportunity to reduce the file size, while saving it on disk with the same frame size and at the same high visual quality. How to get out of this situation? You can, for example, store images in JPEG2000 format with the file extension jp2 or j2k. The compression algorithm and the format itself have been known for over 10 years. Nevertheless, there is no need to talk about its widespread use. That's because his "big brother" JPEG is firmly holding on to its position.
