JPEG Optimizer allows you to upload and compress your photos online. This simple tool works, as its name implies, only on JPEG files.
What’s great about JPEG Optimizer is that it allows you to resize your images before you optimize. Resizing your images will save you even more loading time, and with this online platform you don’t have to split your workflow into two steps.
JPEG Optimizer also allows you to select your own optimization level, which lets you control the quality of your optimized image. This feature is especially important for photographers, since you’ll want to find the sweet spot between preserving quality and saving space.

Optimizilla manages to reproduce great quality in your images with lowest file size possible. And you can compress both your JPEG and PNG photos with this tool. Optimizilla also features a slider which shows you the before and after version of your photo. That way, you can preview the quality of your image before continuing. With the slider, you can decide how much you want to resize your image before you experience any noticeable quality loss.This online tools is great for batch processing. Optimizilla allows you to upload up to 20 images at a time and to set the compression level for each photo separately.Unfortunately, since Optimizilla only works on JPEG and PNG files, you won’t be able to use it to optimize your PDFs. Some others on this list will be better suited for PDF optimization.
