What's the smallest filesize you can get an image to be?

1 bit (a raw 1x1 monochrome image)

IIRC the smallest we could get here is 30 bytes.

If no requisites, this >>57234731.

What's the smallest Pepe

>>57235119
why? because of resize?

summoning webp autist

Couldn't you just program an image?

>>57235384
yea just have to write a gui in node.js to put deep learning on my big data

>>57234731
raw images have headers containing EXIF and such.

>>57235397
>raw images have headers
i don't think we're talking about the same thing here

>>57235443
just because the filename ends in ".bmp" doesn't make it a valid windows bitmap file

>>57234539

oh look it's this thread again

what's the point

>>57234731
please show us how you write a single bit to a file

>>57235476
Then what kind of "raw" image are you talking about?

>>57235537
where did i say i could do that?

op didn't mention files

>>57235537
Let's build a computer.

>>57235566
yes he did you retard

>>57235566
even if he didn't mention FILEsize, good luck writing a single bit to RAM.

>>57235737
either way, the smallest possible image is 1 bit
not being able to directly work with only 1 bit is another issue (one of overhead)

you also can't store a file on a hdd without it taking up at least 512 bytes (or 4096 bytes for more recent hdds) due to that being the smallest addressible unit (a sector)
does that mean a file can't be smaller than 512 bytes? no, it just means they just incur some overhead at a lower layer

>>57235737

#include <stdio.h>

main () {
 struct single_bit {
  unsigned int bit : 1;
  unsigned int bits : 7;
 } a;
 a.bit = 1;
 if (a.bit) printf ("I've wriiten a bit!\n");
}

Yes, and?

>no one's mentioned the empty image yet

>>57236160
What empty image?

>question what the smallest valid image is
>nobody cites the specs
We need to bring back /prog/

>>57236327
The smallest valid image is obviously the smallest image you can post to 4chan.

I doubt webp can beat >>57236070
It has too much metadata.

>>57234539
just make an empty file and change the extension :^]

If we consider mechanical computing, this file is equal to 0 bit.

Your "file" is one line of code. One FORTRAN statement.

Technically that isn't the smallest possible file. Only the smallest file that is considered a non-corrupt file by 4chan.

By GIF's specifications this is the smallest:
