Hey I'm looking for compression and exporting recommendations!

Unfortunately, I took an awesome picture of a drone in flight while my Nikon was set to save NEF / RAW files.... So I have this great shot I've edited in Gimp and it appears crystal clear until I upload it to Facebook.

I've tried setting it to Facebook's sizing recommendations (720px, 960px or 2048px wide) as well as compressing the file size to under 100KB. I export it to JPG for my personal color preferences. The picture looks great on my computer still, and then I upload it to an HD folder on Facebook and it's disgusting... 

Anyone know the exact parameters I should use in GIMP or what I should set each individual compression option to when exporting? Any advice is appreciated!!! I want this photo to sparkle online a little more than what I've been able to achieve so far. Thanks!

Facebook compress all the images uploaded to it. Facebook supports photos that are either 720 px, 960 px or 2048 px on their longest edge. Any other sizes will have their dimensions reduced automatically and it results in a low quality image. Have you tried to upload the Facebook images in a PNG file because i read somewhere that Facebook allow the users to upload the PNG file at any size?

I know nothing about Facebook, but JPEG or JPG is an image compression format, so Facebook is further compressing an already compressed image. If what Claire22 says is true, export your RAW image as a .png (or other non-compressed format Facebook will accept) and go from there. If you choose .png, then when you press the "export" button, it will open an option screen and you can adjust the image size. Push the slider control left to "0" (no compression) for the highest quality and then save.

So, you would:

Open your pic in Gimp

File >Export as >(choose your format and name the new file)

OK

Slide the compression adjuster to "0".

Save.

Wish I could help you more, but I am clueless as to Facebook.
