Is it possible to convert a 300 DPI image of size 500kb to 75 DPI of size less than 75 kb?

@RaMathuzen My suggestion is grab a graphics design software that lets you try different resizing/resampling methods and give it a shot
I like paint.net :D

ooh that too
I often also play with quality settings
it helps with size (and uh, I sometimes need intentionally poorer quality images)

HEIF files are supposed to be smaller than JPEGs and better quality.
High Efficiency Image File Format (HEIF) is a container format for storing individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio and video.HEIF can store images encoded with multiple coding formats. A HEIF image using HEVC requires less storage space than the equivalent quality JPEG. It "can store twice as many pictures in the HEIC format as in JPEG". AVIF refers to HEIF images using AV1 coding. It has "file size 10 times smaller than JPEG with the same image quality". HEIF is also capable of storing animation...
