Gif

I would like to modify the text in a GIF.. Any editor available?

?? Is it animated? If not then you can use Paint. If it is download the free old version of PSP, it has an other exe in it, ani***.exe, you can open animated gifs there, and you can use PSP to alter the diffrent frames..

Either way your still gonna have an issue of the pixels that were covered by the text to start with. The color of these will not be known if by edit you mean remove in anyway the existing letters. First of all you will have the issue of identifying the charaters on the image too.
