HDRU to GIF Conversion: FAQ

What are HDRU files?

HDRU is a rare image format associated with a currently obsolete image handling program called Apollo HRDU. HDRUs are considered old and uncommon, and are difficult to open with regular image viewers, but in case you found one it's probably best to convert to a more accessible extension, such as JPG or PNG.

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.
