Recently, a client of ours was looking for ways to reduce the size of uploaded images on their site without burdening the authors. To solve this, we used the module Image Optimize which allows you to use a number of compression tools, both local and 3rd party.
The tools it currently supports include:
- Local
- 3rd Party
- Resmush.it (General)
- TinyPng (PNG & JPEG)
We decided to avoid the use of 3rd party services, as processing the images on our servers could reduce processing time (no waiting for a third party to reply) and ensure reliability.
