From time to time you would need to upload a GIF (animated picture) online, but for some reason it wouldn’t. Sometimes the server doesn’t accept it, or the GIF itself is too big.
In the second case, you would require to crop the GIF, change its dimensions. There are desktop software tools for that, as well as free online ones.
One of such free online tools for changing a particular GIF’s dimensions is GIFMAKER – a really simple, yet working solution to change a GIF’s dimensions. This online gif resizer is easy to use – you simply upload a GIF, write the necessary dimensions and push the “Resize GIF” button to perform the conversion.
It should be noted that GIFMAKER also allows to change dimensions of JPG and PNG files, as well as change the animation speed.
