When I post pictures I try to make them smaller to not take up too much space. Does that help and what size should I aim for? Less than 1 MB? 500 kb?
I am aware that I can join pixelfed who's servers might have different rules and then transpost a link here to mas.to.
(joinmastadon.org says:
Images (PNG, JPG, HEIF, WEBP) up to 16MB. Images will be downscaled to 8.3 megapixels (enough for a 3840x2160 image). Up to 4 images can be attached, per post.)
