4.2.9 reduces memory usage by up to 33%

A new version of the Windows image editor, 4.2.9, has been released on January 31, 2020. The new version of the image editor includes significant performance improvements as well as other changes and bug fixes. 4.2.9 is the first stable update of 2020; it is available for desktop versions of Windows and can be downloaded from the developer website or the Microsoft Store. If is already installed, it should notify the user about the update so that it can be downloaded and installed. A click on the Settings icon and the selection of Updates > Check Now runs an update check immediately as well. 4.2.9

The biggest change in 4.2.9 falls into the performance category. The developer of the application managed to reduce overall memory usage of the image editor by up to a third by eliminating the “per-image scratch buffer”. The change is not the only performance related improvement in the new version.

As far as memory usage is concerned, usage was also reduced when “working with many tools” by “consolidating homogeneous tiles” and when printing.

Performance of certain operations has been improved as well. The developer lists the following items with improved performance:

  • History actions such as undo, redo, or commit (by switching from NTFS compression to multithreaded LZ4 compression for history files).
  • Undo and Redo with complex selections.
  • Image > Flatten.
  • Invert colors and desaturate adjustments.
  • When saving files.
  • Effect rendering.
  • Finishing actions of most tools.

All of these improvements should be noticeable when using the application.

The new version of includes two new translations (Hebrew and Slovak), and a new “busy spinner” icon that is displayed when the Magic Wand or Paint Bucket tools are being used in the editor. 4.2.9 features several fixes, among them several crash fixes. Last but not least, two plugins were updated as well in the new version.

Closing Words is a high quality image editor for Windows that is updated regularly. The updates include fixes but often also improvements or new features, and that is one core reason why the program is popular.

Now You: which image editor do you use, and why?

Pingo is a fast image optimizer for the Web

Pingo is a free software program for Microsoft Windows and Linux devices to optimize images for web publication and other purposes.

Pingo is a command line utility but Windows users may download the graphical user interface version called Pinga instead.

The application is provided as a 64-bit program only. Compatibility information is not provided but it should run on any recent version of Windows and on most Linux systems.

The following review looks at the GUI version of the image optimizer for the most part. Note that the command line version is included when you install the GUI version. You can check out an overview of important commands here.

The GUI version

The program supports only a handful of formats at the time of writing. While it does support PNG and JPG, arguably the formats most commonly used on the Web, it lacks support for most image formats; this limits the program’s use especially when you compare it to a program like File Optimizer which supports pretty much any format under the sun.

Still, if you work with jpg, png,, webp, and apng formats exclusively, you may find it useful nevertheless as it offers several interesting options.

You can drag and drop images to the interface to add them to the processing queue. Any format that is not supported is ignored automatically. Each image is listed with its full path and size in the interface.

All processing options are displayed at the top. The main features of the image optimizer are:

  • To strip PNG and JPG metadata.
  • To select a default quality level.
  • To select resize, rotate, colors, and enhance options for JPG images.
  • To set the compression type, e.g. lossy or lossless.
  • Image transformations, e.g. to make the images grayscale or disable transparency.

Once you are done select optimize to process all images in the queue. Processing is quite fast and you will notice that the new file size and the size reduction in percentage is displayed.

The program features no preview option or test run option unfortunately. Programs like ImBatch provide preview options which improves the entire process especially since you get previews without having to process the files first.

Another thing that users need to be aware of is that it processes files directly. Means, files are overwritten so that you should use the program to work on copies only to avoid any resulting issues.

Closing Words

Pingo/Pinga is still in early development and things may improve in the future. It is quite limited in the current version and the lack of previews makes it quite difficult to work with.

Now You: do you use image optimization programs or editors?

The developer of released a new version of the image editor for Microsoft’s Windows operating system on July 13, 2019. 4.2 is an update for the desktop version and Microsoft Store version of the image editor. The new version is already available for download on the official project website. Updates of the Store version and installed versions may take up to a week if automatic updates are enabled.

Desktop users may run a manual check for updates to download the new version immediately; this is done with a click on the Settings icon, and selecting Updates > Check now in the Settings window. 4.2

To put the 4.2 release into perspective. 4.0 was released in 2014, 4.1 in 2018. The developer of releases updates regularly but major updates like 4.2 are rare.

One of the major new features of 4.2 is support for the HEIC file format. Support is not available on all supported versions of Windows, however. HEIC support is only available on devices running Windows 10 version 1809 or newer, and only if the HEVC Video Extensions application is installed.

The developer mentions the paid version for $0.99 only but there is also a free version available that users may want to give a try. Microsoft included the codec initially in Windows 10 but moved it to the Store when it released the Creators Update for Windows 10.

A quick test on a Windows 10 version 1809 confirmed that the free version is enough to display .heic images in the image editor.

The format is used as the default format on Apple iPhone devices and also supported on some devices running newer versions of Android.

Core file types, including BMP, GIF, PNG, JPEG, and TIFF — have been upgraded internally. The developer built them on top of the Windows Image Component instead of GDI+ which also introduced new functionality such as support for saving 32-bit BMP images with alpha transparency, support for larger JPEG, TIFF, and PNG sizes, or saving TIFF images at 25-bit and 8 color depths. did not really handle very large images, those starting at 32kx32k pixels, well performance-wise. Users who had to edit these large images noticed that performance would drop of significantly  and that it could take anywhere from several seconds to a minute before the application responded again.

Other changes in 4.2

  • New keyboard shortcuts for changing the current layer are available now:
    • Go to Top layer —  Ctrl-Alt-PageUp
    • Go to layer Above — Alt-PageUp
    • Go to layer Below — Alt-PageDown
    • Go to Bottom layer — Ctrl-Alt-PageDown
  • Support for saving PNG images as interlaced.
  • TGA images load about four times faster than in previous versions.
  • Errors are reported in the Save Configuration dialog. Also, some performance improvements.
  • Fixed Windows Explorer thumbnails for certain image types, PDN, DDS, and TGA, that were not rendering alpha correctly.
  • Improved CPU usage for thumbnail updates.
