I tried using 'JPEGmini' and 'JPEGmini Pro', which can reduce the size of JPEG file up to about 1/12
I want to keep the file size as small as possible when uploading photos to SNS or online storage or sending them as an email attachment, but I also want to avoid image quality degradation. The software for Windows and Mac ' JPEGmini ' that can reduce the size of JPEG file will meet such demand. As there are trial version with limited functionality, paid version with removed functionality, and pro version with some more features, purchase pro version and compare it with trial version as to how much difference there is. The
JPEGmini-Your Photos on a Diet!
JPEGmini is software that you install and use, but you can also check the power of file size reduction on the official site. Click 'UPLOAD PHOTO' at the bottom left of the image displayed on the top page.
Drag and drop the JPEG file you want to test into the gray frame, or click 'Press to Upload Photos' to select the file.
File upload and processing is done ...
You can see the result. On this screen, the left side is the original, the right side is the photograph processed by JPEGmini, and the border part can be moved to the left and right by dragging. In the case of this file, the original is 17 MB (17923 KB) and 3791 KB after JPEG mini processing. The original consumes a capacity of 4.7 times.
◆ Installation of JPEGmini
There are three types of JPEG mini: “JPEG mini” for home users, “JPEG mini Pro” for professional photographers, semi pros and creators, and “JPEG mini Server” for sites with many photos and commercial sites. There is a free version with limited functionality for trial use in 'JPEG mini' without a mark, so we will use this first.
Click 'Download Free Trial' on the following page.
JPEG mini | Download the Free Windows App
Click 'Save File'
Since the file of the icon like ' JPEGmini_installer.exe ' is an installer, it starts.
Then file download and installation will start
Check the lower left check box and click 'Accept'
Check out 'Use JPEGmini free version' and click 'Continue' to try it out. There is a limit of 20 files per day.
◆ Setting of JPEGmini
The main screen looks like this, and the remaining number that can be used in one day is displayed at the bottom of the screen.
Click on the lower left 'Optimize Originals' to open the option settings screen.
By default, Optimize Originals above is checked. In this state, the dragged and dropped original file is optimized as it is. In addition, warning is given at the time of overwrite. If 'Send anonymous usage information' at the bottom is checked, anonymous usage information will be sent, so those who care about it will uncheck and click 'Apply'.
If you select 'Export to Folder' below, the optimized file will be output to the specified folder. If you are in trouble when the original file disappears, choose this.
Also, if you check Resize Photos, the vertical and horizontal size will be resized when optimizing the file size. There are five choices: Small (960 × 720), Medium (1600 × 1200), Large (2592 × 1944), Max Width, and Max Height.
For 'Max Width' and 'Max Height', enter the maximum horizontal or vertical size and click 'Apply'. Small, Medium, and Large seems to be forced to have that resolution, but actually it is scaled down while maintaining the aspect to fit in that size. For example, when an image of 1200 pixels x 800 pixels is reduced by 'Small', it is output as 960 pixels x 640 pixels (hereinafter referred to as px notation).
◆ Try using JPEG mini
So, let's actually use JPEG mini. The subject is a photo of this tram I tried earlier in the browser version. What is up in the article is a file that is simply shrunk to 560px wide (1200px wide after clicking), and the original photo has 6016px width.
The file size is 17.5 MB. With this, I can not upload to SNS etc ... indeed.
JPEG & PNG Stripper , but the reduction width is about 100 KB and water on burnt stone.
Since deleting the metadata can reduce the file size only a little, I tried to delete the metadata of this file using the
Therefore, the file size is reduced by 13 MB when using JPEG mini.
Both the original as-photographed and the previous metadata deleted version have greatly reduced the file size. As JPEGmini doesn't delete metadata, if you want to delete metadata, you need to use another software.
The appearance of the photo itself looks like this, and we do a simple reduction for the article posting as before.
It will be like this if you cut out only a part. This is before processing.
This is after processing. If you are a person who prints, you may be concerned about subtle deterioration, but it will be difficult to notice the difference as long as you look at photos on a PC or smartphone.
By the way, the original size was 4.7 times the size after JPEG mini processing was the same as the browser version, so I checked it, and it was shrunk to the exact same file size.
◆ Try using JPEG mini Pro
JPEGmini is $ 19.99 (about 2480 yen) in the regular version without functional restrictions, but JPEGmini Pro is different in figures from $ 149 (about 18,484 yen). In the end, I decided to actually try out how much power would be gained with Pro.
Click 'Buy JPEG mini Pro' on the following page.
JPEG mini Pro | Photo optimization for professional photographers
If there is no mistake in the input content, the purchase is complete.
Within 10 minutes, you will receive an email with the subject line 'Your JPEG mini Pro Delivery Information' at the registered email address.
Download and install the Pro installer from the URL described in the email. The procedure is exactly the same as JPEG mini.
The difference is almost only an icon. If you check it and click 'Accept', the procedure from here is Pro only.
Enter the activation code sent by email and click 'Continue'.
Check the check box and click 'No Thanks'.
The appearance of the basic screen, setting screen, etc. is exactly the same as JPEG mini.
Furthermore, the file optimization part actually works exactly the same. This file property, the one on the left is optimized with JPEG mini (as shown above), the one on the right is optimized with JPEG mini Pro. It matches in 1 byte unit. In other words, it does not mean that the file size can be made smaller than the regular version.
The difference between Pro and Normal version is that 'Normal version can handle only 28 megapixel photos, but Pro can handle up to 50 megapixels' 'Pro is 8 times faster than regular version' 'Lightroom plug-in is There are three points. I wanted to test whether it was really eight times faster, but because the trial version of JPEGmini can only use up to 20 sheets per day, I did not see the difference that I could see in the trial with 10 sheets.
So, I tried how long it takes to process 1000 sheets. The photo is about 15MB or more, and there are 15.9GB for 1000 sheets.
The process goes on and on, but even if you move it from the SD card to the PC, the processing of 1000 photos that you have a hard time seems to be very hard ....
It takes 17 minutes and processing is complete. Finally, a dialog asking for 'Please rate JPEGmini Pro' was displayed, so click 'Not Now'. If you get a dialog at this timing though you have purchased ....
Thus, the folder after processing has become significantly slim with 3.12 GB at 1000 sheets. Each photo is about 2MB to 6MB.
As a conclusion, if you only plan to process up to 20 cards a day, it is sufficient to use only the official site or the trial version. If you do not plan to use 'Lightroom plug-in' which JPEGmini automatically optimizes the file size when exporting files from Adobe photo editing software Lightroom , first use JPEGmini. It is better to start from where you try. If you are not satisfied with the speed, buy a Pro when the Lightroom plug-in is required.
