No compromises

Image quality is paramount, when it comes to astrophotographs. Compression artifacts are much more visible on them, because of the low signal-to-noise ratio.

One of AstroBin's more central points, and one the very reasons it was created, is to enable the amateur astrophotography community to store, preserve, and share images at the maximum quality that's possible.

Astrophotographs are not like regular daytime pictures: if you apply JPEG compressions, artifacts will be much more visible, and nobody wants that after spending many nights out and many hours post-processing to reveal the faintest and finest details.

For this reason, even the entry level subscription plans on AstroBin allow for very large upload sizes, and the AstroBin Ultimate plan poses no limits to image size other than what is technically achievable.

Images are permanently stored in full size and full quality, and when smaller versions are generated for thumbnails, they are resized with the maximum quality that's possible.

General purpose image hosting website, and the popular social networks, heavily compress your image in order to save space and bandwidth (which is understandable, because they have millions-to-billions of users, literally). On the other end, AstroBin focuses on quality over savings, and the difference is stark!
