I use Resizing.app to resize my photos not just by resolution, but also for optimizing the file size and dimensions for every platform I need! It's so fast and intuitive. There's no need to log in, just upload and resize is there! Other apps or platforms require logging in or signing up, but with Resizing.app, it solves that problem. Just go to Resizing.app and you can resize with one click, no need to sign up. Review collected by and hosted on G2.com.

Bulk image resizing is still not available. Hoping they will work on that in the future! Review collected by and hosted on G2.com.
