    Exactly what I was looking for. Made it much easier to archive large volumes of previously unoptimized images on backup drives. I especially appreciate the feature that allowed me to set a size threshold above which files should be compressed.

    One of (if not THE) best image compressors around. PLEASE use it and give this person some money!

    One of the best softwares out there to compress bulk images together up to the desired compression ratio. Thanks a lot.

    Everything is good, just if we can add CR2 and CR3 Support

    simplemente sensacional. La compresión es bastante buena. Permite elegir perfectamente los porcentajes de reducción, calidad, etc. Y en tiempo real ves el tamaño final de la imagen. Y lo más importante, es rapidísimo si quieres comprimir del tión varios miles de imágenes. He probado con otros softwares y lo que este hace en minutos, en otros puede llegar a costar varias horas. Solo un consejo al desarrollaador. Estamos, por desgracia en época de webp :) larga vida al código abierto.

    500+ images compressed in 5 minutes from 1.01 GB to 65 MB. And you can barely see the difference in quality. Unbelievable.

    Had to login to leave a review on this. This software is fully automated and can compress thousands of images in no time. This has really improved my the load time on my websites for SEO. This is an awesome tool! For so long my website load was slow. I also scanned this with many anti-virus tools including Virus Total. This software is clean! Thank You!

    This tool is a definite treasure for web designer. It really optimize compression, and does it via batch queries. Great automation.

    No very good looking interface, but main bug is: no mapped network drive in explorer! Why? No network discs, no network computers... Why ? i.imgur.com/wl8Vbwb.png i.imgur.com/x4bwpO2.png With Regards Jaro

    Try our latest version (4.1.0), provide full network path such as :\\pc-name\shared-folder as input location and add that to Compression List. We have also tested the software where output images can be saved at network address. Please make sure you have appropriate access rights to the network location.

    A very easy project to use. The settings are dead simple and there are very few to confuse the user. This app did a fantastic job of compressing a large folder structure of artwork. Additionally the application does a great job at preserving the transparency of png files (which can be a problem with other software, Irfanview for instance). A feature I'd like to see added is "set long side to X pixels." Currently only "width set to X pixels" is implemented.

    Today I found my Afelo picture compression utility no longer works on Win8.1. (JRE 8.144). I even tried a reinstall of Afelo and installing an earlier version of Java (JRE v7.9). I went hunting for a new program an found MassImageCompressorV2.0.0.zip here on SourceForge, which actually seems to contain Mass Image Compressor Vv1.0.0, based on the installed MICompressor.exe . I gave it all 5's except for Support, which I gave a 4 only because of the v2 vs v1 issue I just mentioned. Great program. Thanks!
