FAQ
J2K to GIF Conversion
What are J2K files?
J2K represents an upgrade of the JPEG format, including more features, such as supporting transparency and alpha channel, or lossless compression. J2K is part of a larger pack of improved JPEG extensions, known as JPEG2000, together with formats such as J2C, JPX, JPM or JP2. Most of these formats are compatible with mainstream image viewers, but do not enjoy the popularity of JPEG.
What are GIF files?
GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
