Mass Image Compressor is free image compressor software and converter running on Windows desktop, which is easy-to-use and best for website image optimization, and of course, it’s freeware and ad-free.

When launching the OSJOY.com, I used tinypng.com to compress JPG, PNG, GIF images online, and the compressed rate is always excellent, the speed is fast, everything is very well. Even I tried many other online image compressors to reduce image size for web; you know what? Tinypng.com deserved the best.

Still, the downside of Tinypng free version only allows users to drag and drop to 20 images and the file size max to 5MB, that means if you want to compress more, you should go Pro version which takes you 25$ for one year per user.

Which means if you have more than 20 images, there is a problem. Don’t we have Tinypng alternative desktop version for Windows?

The answer is yes. Mass Image Compressor can do the job for you.

Features

  • Reduces image size up to 90%
  • Optimizes all images in a folder
  • Allows to resize the image
  • Preserves image EXIF Metadata
  • Image Format supports: JPEG, PNG, RAW

How to use Mass Image Compressor?

  1. Download Mass Image Compressor and double-click to launch.
  2. Choose your photo folder with … button.

Well, the settings are dead simple; everyone must have no obstacles to use it. That isn’t our focus, right? And we would like to know the compressed quality made by Mass Image Compressor, do we?

For this time, Mass Image Compressor Wins, however, I couldn’t tell this freeware will be always the best in any situation, it depends, I have to say. You can test it under strict conditions, but to whom those don’t like to use image compressor online and are looking for the one can be used on Windows Desktop with batch compression.

You can try Mass Image Compressor.

If I really need to find downsides of Mass Image Compressor, I have to say the software doesn’t support drag and drop. Despite that, it deserves the best.

A Suggestion of Using This Image Compressor Software

The software set New Dimension in 70% and 80% in Compress Parameters as default.

When I used this project for the first run, I haven’t noticed it yet, and yes I got an inaccurate rate to compare with Tinypng.com, thus, if you would like to keep the original dimension of the photo, enter 100 instead of 70 like above. If you want to resize the image, just set Fixed width or set in target number.
