best image optimization software

Image optimization is essential for both professional and home use. This is especially important if you’re an online publisher or blogger. Most of the websites (focus on social networks) have limitations for image size. So, you have to optimize photos in order to use them online.

In addition, the large image files that you add from your gallery will increase website page size and thus, largely increase loading time. And we certainly don’t want that. Because the common visitor wants that page to load in a blink. On the other hand, we neither want to trade so much of the image quality for improving the site speed. So, compromising between size and quality is the only viable option.

In that manner, we’ve prepared some fast, online and offline tools for image compression and optimization. All of them are free to use.

Files remain in their original format and there is no need to unzip before using them. It also allows you to customize the balance between quality and compression ratio, which is a very useful feature for images.

It’s very user-friendly: just select the file you want to compress, choose your compression level and click the ‘Optimize’ button.  You can also optimize files from within Windows Explorer and Microsoft Office programs, or choose to automatically optimize email attachments as they are sent.

It lets you choose between two compressing modes: Lossless or Lossy. Lossless will optimize the size of your photos, while maintaining the image quality at the same. Lossy will compress the photo more but will reduce its quality. Lossless mode supports only JPEG and PNG formats, while Lossy works out with the following 4 formats:

  • JPEG
  • GIF
  • PNG
  • SVG

The Compressor is simple to use. You select a preferred optimizing mode, upload your image and it gets automatically optimized. A nice addition is a split screen preview that lets you see the exact difference in transition. A tool supports only one file per compression up to 10 MBs of size.

JPEG Optimizer

JPEG Optimizer is a simple and reliable online tool for both compressing and resizing images. It kind of lacks the advanced features, but it gets the basic job done. Furthermore, the files can be compressed from 1 up to 99 percent, but have in mind that photos will lose a lot of original quality.

The procedure is simple:

  1. Upload a photo (JPEG, GIF, PNG, or BMP)
  2. Choose compression level (from 0 to 99).
  3. Select preferred width in pixels.
  4. Click Optimize.
JPEG Optimizer supports only one file per conversion up to 10 MBs of size. You can try out JPEG Optimizer here.


Optimizilla is a well-designed online tool for image optimizing. The interface is great and easy to use. It supports only 2 file formats: JPEG and PNG, but since these are the most common formats, you shouldn’t have any major problems. Even though some other solutions support more formats, most of them don’t have the drag-and-drop option. To optimize your photo using this tool, do as follows:

  1. Choose up to 20 files, drag-and-drop them in a marked area.
  2. Once uploaded, select an individual file in the queue.
  3. Use sliders to choose optimization level (more quality – less compression).
  4. Compare images to find wanted optimization.
  5. Download files in the standard manner or in a ZIP archive.
