Does 4chan support bmps? What is the maximum file size? What

Yes, but you'll have to process your BMP through imagemagick first.

It doesn't. I think it used to say next to the file upload box what you could upload.

It did, it also had the maximum allowed filesize for each board.

JPEG, PNG, GIF, and WebM are allowed everywhere except /f/ which only allows SWF files.
/po/ also allows PDF files.
I think the default max filesize is 4MB now but I'm not sure. A few of the boards allow larger files.

Oh and also regarding WebM
VP8 video only
On /gif/ and /wsg/ you can have vorbis audio.

I think there's a maximum of 2 minutes for WebM.

It's 4MB for images, and 3MB for webms I think. 10 000 x 10 000 resolution. 3 minutes for webms.
/gif/ and /wsg/ have longer and larger webms with sound. /p/ doesn't strip jpgs unlike other boards.
They're some pretty stupid rules, and they should unify them and post them somewhere to be honest.

2 minutes for boards other than /wsg/ and /gif/. On there the limit is 5 minutes.

/f/ still uses the old formatting where you can see the limits. I have no idea why hiro decided to remove these from around the post box.

Let's test.

>>61174614
I think these got removed way back before hiro came on board.

>>61174614
Pretty sure these have been removed for longer than Hiroyuki has been admin.

Anyway, I'm all for bringing it back. Encourages people to read the FAQ and Rules before posting, and gives some info about max filesize and such. Very informative and very useful, and if you don't want to see it, just use CSS.

>>61174614
I'd thought they were removed some time ago, like around the time webms were introduced. Or when submit was changed to post.
It's probably in an attempt to not confuse normies, better to just say something doesn't work and let people try than to scare off people that don't know what a jpeg is.

I told you man.
