I have used the converter and it is very good! I just have one problem, that is I can't find an option to change the width of my spaces. I want the spaces in my font to have a width of 3 pixels, but the converter defaults it to 4.

Also, it seems that the space characters are also taller, this is not too much of a problem but it's quite weird that I can't find an option to change how spaces work. I use this font in Aseprite. If you can imagine, all my characters are 5 pixels tall, and the "tiles" I made are 7 pixels tall. When I use the font in Aseprite, it maintains it's 5 high size without spaces, but with spaces it becomes 6 high with an added top part.

Is there an option which I just missed so I can edit spaces?

Edit: also I've noticed I need an 8 font size in Aseprite for it to work, maybe it's just depends on software but it's just weird to see an 8 out of nowhere

Whitespace width is the width of whatever you’ve put in your space character. If your font does not have a space character, it’s up to software to decide what to do with that (it’s probably taking a taller space from Arial/whatever)

Oh, so you mean I can add a blank tile for space width? How will the converter determine the size then if there is no glyph color? I just tried using a blank tile and adding a space character in the  "Glyphs in image" section, but it turned the space into a one pixel wide character, which should help, I just need to use double spaces.

I also just realized that each character already has a 1 pixel space in front of it, adjusted by the "Spacing" option. So my previous comment actually means "I want the spaces in my font to have a width of 2 pixels, but the converter defaults it to 3."

If there are no other options, then it's fine, because at least I can resort to using double spaces which is more manageable than wider spaces.

The number of pixels in your space character will be the width of the space - see the example font.

Ohh! I get it now. I genuinely thought that was just a full stop. Thank you so much for your website, it's the only thing that worked for me!
