Compress Now is a great tool for optimizing images. It lets you compress JPG, GIF, and PNG files, which are three of the most common image file types. It also has a few other useful features, such as letting you choose how much you want to compress the image you upload.
The largest file you can upload is 9 Mb, or 9000 KB, which is much bigger than the two images we showed you. When we ran the test, we set the compression level to 65%, and the difference between the original and the much lighter compressed version was hard to see with the naked eye.
The Good
- Interface that’s easy to use
- Helps a lot of different image formats
- Options for custom compression
- The ability to compress in batches
The Bad
- Compared to other platforms, it has fewer features.
- Image quality could be hurt by compression.
JPEG Optimizer

Feature | Description |
---|---|
JPEG Compression | JPEG Optimizer is a specialized platform that compresses JPEG images specifically. |
Custom Compression | Users can select the compression level and image size to meet their specific needs. |
Preview Feature | The platform provides a preview of the compressed image before users download it. |
No Watermarks | JPEG Optimizer does not add watermarks to the compressed images. |
JPEG Optimizer is a good option if you only need to compress JPEG images. As the name suggests, it doesn’t work with PNG or GIF files. Most of us should be fine with the default compression setting of 65%, but the website can compress images anywhere from 0-99%.
Using just the default setting, I was able to reduce the size of the image to almost half of what it was before, and I couldn’t tell that the quality had changed. You can also change the image’s dimensions and set the maximum size (the default is 4mb).
The Good
- Specialized JPEG compression
- Options for custom compression
- Check out a feature
- No watermarks are added to images that are compressed.

- There may be a drop in image quality if only a few formats can be used.
