How do I make an existing animated GIF loop repeatedly?
I have an animated gif which, as originally created, animates once then stops. I want to modify the image file so it loops forever instead.
What free applications or command-line utilities for Mac OS X can I use to do this? I've found several GIF utilities that can create new animations, but none that let me tweak the properties of existing ones.
Solution 1:
Solution involving the Terminal:
- Download the sources of Gifsicle
- Unpack the sources and go to the unpacked directory
- Do
./configure --disable-gifview --disable-gifdiff - Do
make - Do
cd src - And finally do
./gifsicle -bl /path/to/image.gif
Solutions using GUI tools (I didn't test any them!):
- You can try GifBuilder (requires Rosetta to work with Snow Leopard).
- Pixen also seems to be a GIF Editor.
Solution 2:
You can use ImageMagick. You just run:
convert -delay 20 -loop 0 nonloopingImage.gif loopingImage.gif
You may need to install ImageMagick first.
If you use brew you can: brew install imagemagick from the terminal, then you can run the convert command.
Solution 3:
GIMP can edit animated GIFs; open the image in that then save it again. You will be asked a few questions, and one of the available options is to loop forever.
It is apparently possible, or even easy, to install GIMP on OS X, but I can't say I've done it,
Solution 4:
Assuming you already installed Homebrew and run brew install imagemagick.
Just use the command line to do:
convert -delay 15 -loop 0 input.gif output.gif
And this edits your existing image without modifying the existing durations:
mogrify -loop 0 Untitled.gif
