Here's a comparison with a simple image:
Irfan (without PNGout), 2,164 bytes

Xnview, 1,943 bytes

PNGout, 1,213 bytes

...and just for comparison: GIF, 2,084 bytes

maybe a admin could resend it? i dont find where to get it myself - cause "forget my password" doesnt help and the rest is french et mon francaise est ne pas très bien, seulemente en peut que je apprend sur l'école
The original gif image has 45 colors, these 2 have 16, no wonder why they're smaller...Drahken wrote:1016 1111
I just ran a test making a PNG with Xnview, then using the PNGout standalone prog to compress it further:
XNview: 1,111 bytes.
PNGout recompressed: 1,016 bytes (nearly a 10% savings).
ladiko, your account should be active, now. Please let the admin know if this is not the case.ladiko wrote:p.s.:i dont get the email to activate my account "ladiko"

How does that disagree with what i wrote?Drahken wrote:It does more than that. Make a PNG wih xnview using any filter/settings you want, run it through pngout and you'll find it much smaller. 2 drawbacks to pngout are that it only works on indexed (256 color) png, and it takes a while to compress the pic.
You suggested that one could try and manually select the best Compression method in XnView... while Drahken precised that PNGOut would always provide a much smaller result than this suggestion.Danny wrote:How does that disagree with what i wrote?
