How would I go about making an image's file size larger?

you gotta add more "data" to it. more colors, filter, shit, anything.

File: Steganography-Hidden-Message-in-Image.png (200KB, 740x194px) Image search: [Google]

200KB, 740x194px

i think changing the compression could be more faster, or maybe some steganography method -link below

*way faster

if it's lossless, pure noise is theoretically incompressible, and will thus have a good chance of being large. otherwise, just add a shitton of metadata or something.

Why?

GIF is a bad choice since it uses some techniques like color mapping to reduce file size (every pixel maps a value to a predefined pallette).
This is also how gif does transparency.
PNG on the other hand uses separate 'channels' (think of them as layers with blend modes) and does not uses gif's color palette technique.
Save that inage as a png that supports transparency, and make sure not to save it as interlaced and it becomes huge.

copy image.jpg + win_10.rar annoyingimage.jpg

Would that do the job? It'd certainly take a while to download

except that image you have is not noise at all, that's a simple repeating pattern.

also pure noise that is generated by a computer isn't really pure noise.

also learn about how compression works, psds are compressed by combining groups pixels sharing the same color value data across individual color channels. the more unique colors you have, the larger the file.
