The DCM file format is a specialist image format used in medical circles. They are used to contain images of X-rays, CT scans, or MRIs in a standard format that can be shared across the industry.

Within the DCM file can be several medical images, which are often accompanied by important patient data and surgical routine data, all stored as metadata within the file.

As DCM is a specialised format, it can only be opened and viewed with similarly specialised software. We have tools that allow DCM files to be converted to other, more accessible formats, such as JPEG.

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.

The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.

One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colours down to 256 or 16 colours to help reduce the file size of the PNG.
