Question

Any open source tools for website thumbnail creation on the fly or for storing on server side??

Most of them provide limited no of thumbnail requests per month in free mode. Are there any services/ tools that’re completely open source ?

Answer 1

wkhtmltopdf does the trick:

$ wkhtmltoimage http://stackoverflow.com so.png

You can convert image formats on a Linux box:

$ convert -sample 100x75 so.png small-so.png

Or you can script it for all the images:

#!/bin/bash
for i in *.png
do
  convert -sample 100x75 "$i" small-"$i"
done
