ARW to PNG converter

.arw

ARW is a format used to store raw captured photos by Sony digital cameras without their compression to other file formats such as JPEG. The format adopts basic specifications from TIFF and maintains the full set of image data. In some cases, the data is minimally adjusted depending on the camera type or model. Unlike image file formats compressed like JPEG, files using ARW are larger, details and cannot be easily viewed. This means they require special programs that can be used in opening and converting them.

The ARW format provides its users with the freedom to make changes or adjustments to an image as they see fit. Converting ARW images allows viewing of images on internet browsers. The camera model used determines the type of format captured despite using a similar .arw file extension. This is possible due to the presence of sensor variations in cameras. The differences presented are significant determinants of the software used to view, convert, or store an image.

PNG – is a scan-line graphic format developed as an alternative to GIF, a commercial license. However, they are both raster image types. PNG is based on the best features of the predecessor, including lossless compression and transparent background support. The PNG technology ensures the preservation of all stages of editing and the restoration of the step by preserving the quality. However, it does not allow us to save several pictures in one file at once, limiting its use in the development of animated images.

The PNG extension was proposed as a tool that helps to transfer and store images on the World Wide Web. The technology is limited to an 8-bit transparency channel so that you can adjust the colors from opaque to transparent. It supports 24-bit RGB colors, matching images, and shades of gray. However, as a non-professional format, PNG can not display other color spaces. Most programs allow you to open such files. They can also run in any browser. Images are different in small weight with good quality.
