How may i convert an image from .png to .gif ?
I tried to upload on a site and it work only as .gif extension and i have the picture in .png format.

why would u convert png to gif?

You could try opening the image in an image editing program and saving it as .gif
I don't know about just changing the extension, but that has worked in the past



Usually to decrease the image size

Because i can upload it only in that format.

i would rather posterize than turning into gif

Thank you, i have just found a similar one in .jpg format and worked.
