FAQ

SYN to GIF Conversion

What are SYN files?

SYN is an old and obsolete image format also known as Synthetic Universe. It is similar in size and features with the SYNU format, and might be equally difficult to open via regular image viewers. In case you found or were sent such a file, it's probably best to convert it to a more accessible format before trying to open it.

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.
