The subject line pretty much says it all. I want to upload the highest res image to this site but not sure if that's FITS, TIFF, XISF, or other. Thanks in advance for your advice.

What file format do you save to Astrobin
Well Written
I have always uploaded PNG, it always rejects tiff if I upload that by mistake.

It would be nice if ultimate subscribers could up load TIFF images for display
Hi Mike,
resolution has nothing to do with the format: resolution only refers to the number of pixels.
AstroBin accepts the following formats:
JPG
PNG
GIF
There are no limits on resolution, but there is a 25 MB limit if you're on Free or Lite, 50 MB if you're on Premium, and 200 MB if you're on Ultimate.
For best quality, you can upload a lossless JPG of PNG (i.e. without compression), if that's within the limits of your subscription.
AstroBin will store your original upload, but resize it to various resolutions to display it reasonably (e.g. a 200 MB PNG would be too much to display on the technical card page, because it would make the page load too slow).

Always PNG
A full resolution JPEG would suffice, even when the image contains annotations. For the latter, just compress less when exporting. I find PNGs an overkill for images not contain annotations or other graphic elements. Think about your viewers: PNGs typically are larger thus taking longer to download. Maybe your viewer is under a slow internet connection or he/she's just impatient. I have just experienced this. The waiting for just viewing an image in full-res reminded me the dialup days when images were rendered in our screens line-by-line. Recently I had uploaded a PNG image and I feel it is not a good practice.
