App: batchRESIZE
Developer: Jiulong Zhao
Genres: Education, Photo & Video

Copy and resize an entire folder of pictures with just one simple click. Best tool for thumbnail making too!
It supports various kinds of file formats and can both enlarge and shrink images.  
Modern cameras' shot resolution keeps getting higher and higher, but sometimes, it's not necessary for it to be that large, and the large file size makes sharing difficult. 
batchRESIZE can easily resize these images to save your space, reduce upload times, and save money! 
batchRESIZE is also a useful tool for conserving space on your cloud servers. 
So, after the shot and before sharing, give batchResize a try!
