Hello, I posted my first webcomic “Flat Lids” today and I saw that the image was blurry. Flat Lids

The image is a PNG file 2363 X 800. I original image was a JPEG 3840 X 1300.

What can I do to make it clearer?

Thanks

It looks pretty clear now and it's a PNG. Did you manage to fix the issue?

What I'd normally advise is:
Comic pages are automatically cut down to 960 PX wide and saved as a JPG (I think) so saving it as 960 wide (and a png) to upload it will circumvent the issues of being saved as a compressed jpg.
