Batch GIF resizing program

[PeR930]

What are some good programs that can batch resize animated GIFs? I have about 40K animated gifs I need to process.

I use Gif Movie Gear for all of my .GIF work, but FAIK it doesn't do batch and isn't free.

Back in the day, I used Jasc Image Robot for mass-resize on gif's for webpages. No idea if it's still around.

Install ImageMagick (ImageMagick: Convert, Edit, Or Compose Bitmap Images) and use it from the command line or search for the ImageMagick bindings/wrappers for your favorite language.

For example, for Node.js, there's gm : GraphicsMagick for node.js. Could write a simple loop that resizes your gifs locally.

Off the top of my head:

var gm = require('gm');

// Resize gif to a width of 100px (preserving aspect ratio)
// if it's wider than 100px
gm('example.gif').resize(100, null, '<');

Thanks for the tips.

I was thinking about Imagemagick but it seems more complicated to setup, though cheapest option. I may have to try it out.

Does anybody have any other suggestions?

Yeah, if you're not a programmer, ImageMagick might be a bit too out of reach.

Have you had any luck with any of the programs that come up when you google "batch image resizer <windows/osx/linux>"?

iRedSoft's BatchImage is a good one that I have used. Little pricey as graphics apps can be, but less than many. They have a free trial. Really easy to use, and lots of features. Produces great results.

There are tutorials for ImageMagic on YouTube. Also Google "How to list image files in a directory" and you will have the 2nd part of the script above.

If you still need help with this, I'll write you a quick script for free. Feel free to PM me.

Like others pointed out, imagemagick will do.

Example:
convert [INFILE] -gravity center -resize '400x300' -crop 400x300+0+0 +repage [OUTFILE]

This takes [INFILE] and makes a 400x300 file called [OUTFILE]

Should be easy to make a large batchfile that runs through your GIFs one by one.
