[Pro] If anyone has a second for this (non-FW)

Hi all,

Lately I have been trying to reduce the size of my graphic files especially .png for my site.

I am very perplexed about something. I have a .png that FINDER shows as being 54kb.

I found this site that states they do something amazing- they shrink the size of .png but with little to no loss of quality. When I use the site (which is as simple as just dropping the file on the page) it shows this file INITIALLY as being just 3.7kb (instead of the 54 Finder says) and then produces a new file in this case to 226 bytes.

This is amazing, but I am not sure…

  1. why the size of the file in Finder is so different than when I first drop in in the site (54kb vs 3.7kb). Which is right?

  2. WHen it compresses is it really that small (226 bytes) like Finder now says?

Anyway,

please try the site out and let me know if this is all accurate.

SImply find a .png look at the size, then drop it on their webpage, take notice of their reported size and the NEW compressed size.

Thanks!! Looking forward to hearing your results.

wow - having had a second and gave it a go:

The basic .png had 557KB, the converted 174KB (-74%). That’s pretty cool.

So I tend to say:

As long the basics are good, the tool is doing acceptable things (if it can be said running only one single test). I’ll keep it in mind and do a few others.

Cheers

This tool does the same, is free and runs as application on your Mac.

It has mostly to do with the gamma correction. Some information can be found here: The Sad Story of PNG Gamma “Correction” I use PNGpong, a dashboard extension to shrink my png files. Link: http://ryanschenk.com/PNGpong/ There are some other applications, that will reduce the file size, but I do not know, if all of them can handle the gamma issue.

cool feedback.

Thomas.
Did you notice at all if your .png size in FInder inititally was different than the web site saw it before the conversion?

One .png in Finder says 54kb but when dropped INTO that site it sees it at first as 3.7kb? then converts even smaller. I am thinking either it was never 54kb to begin with (finder wrong) or the new size of 226 bytes (which it then says in finder) is wrong).

seems too good to be true.

öhhhh - yes, Finder 557KB : TinyPNG 551KB - so nothing I should think about - or?

BTW:

Select the image in finder and hit CMD-I (Info) and see the size there: tadaaa

I wouldn’t mind about that much. Usually finder never lies but often includes some “system-space” an item requires.

Ya Thomas, I did that. Your 557 compared to 551 seems real normal.

How would you explain this…

54kb in Finder,
Then hit CMD more info and it says 54kb (53,564 bytes), BUT when it drops into the site it reads it starting at 3.7kb before conversion

That is way different!
