FOR MANY YEARS I HAVE USED JPEGminiPro [BUT I DID NOT UPGRADE TO VERSION 3]
The most recent version is 3.5.3.50941 but I use Version 2.2.9 build 20571. I have downloaded trial copies of Version 3 and could not see any real improvement and could not justify paying an annual subscription that was in fact expensive compared to what I paid for the original. I am in the process of switching to Squash 3 by Realmac [$13.99 per year] as it produces WebP files and because it is a lot less expensive.
JPEGminiPro is a software application that reduces the file size of JPEG photos by up to 5X while preserving the resolution and quality of the original photos. It is a popular tool among photographers, web designers, and anyone who wants to save space on their computer or mobile device.
Pros:
Effectively reduces file size: JPEGminiPro is very effective at reducing file size without sacrificing image quality. In most cases, you won't be able to tell the difference between a compressed JPEGmini photo and the original.
Easy to use: JPEGminiPro is very easy to use. Just drag and drop your photos into the application, and it will automatically compress them. You can also batch process multiple photos at once.
Available for both Mac and Windows: JPEGminiPro is available for both Mac and Windows, so you can use it on any computer.
Cons:
Not as powerful as some other image compression tools: There are other image compression tools that can reduce file size even further than JPEGminiPro. However, these tools often produce more noticeable artifacts in the compressed images.
Not free: JPEGminiPro is not free.
Overall, JPEGminiPro is a great tool for reducing the file size of JPEG photos without sacrificing image quality. It is easy to use and available for both Mac and Windows. If you are looking for a way to save space on your computer or mobile device, JPEGminiPro is a great option.
Here are some additional details about JPEGminiPro:
The software uses a proprietary algorithm to reduce file size while preserving image quality.
The software supports batch processing, so you can compress multiple photos at once.
The software is available for both Mac and Windows.
I could not determine the price as they have changed to an annual subscription:
"Starting with the launch of JPEGmini Pro 3 on October 2020, the licensing model changes. The most important part of this change is that we will now require a yearly fee for updates. Once you buy JPEGmini that version is yours to keep forever, but in order to upgrade to the newest version, we ask for an additional yearly fee. If you are an existing user of JPEGmini, you should receive a popup inside the app allowing you to upgrade with a special discount of 30%. If you don't see the banner inside the app, please email our support - [email protected], with the subject: "Upgrade pricing for JPEGmini Pro 3", stating what was the email that was used to purchase JPEGmini and attach a proof of purchase (this could be a screenshot, or an email with an invoice).
