This is a hotfix for the recently released version 4.3 update.
Get the update
- Microsoft Store release
- You can purchase it here. This helps fund development and is an alternative or supplement to sending in a donation.
- If you already have it installed, the update should happen automatically within the next day or two. To get the update immediately, you can follow the instructions listed here.
- Classic Desktop release
- Download the installer directly (web installer for all CPUs and OSes). This is the recommended download if you don’t have Paint.NET installed. It can also be used to update the app.

Changes since 4.3.1:
- Fixed a hang at app startup on systems using certain locales, such as Thai (th-TH)
- Improved performance of Settings -> Tools, which used to take 6-7 seconds to open. Now it takes about 1 second, thanks to @Bruce Bowyer-Smyth
- Fixed ReadOnlyBoundToNameValuesRule for IndirectUI-based plugins. It was not initializing correctly, although it would work correctly afterward.
Enjoy!

Great load time improvement!
Thanks for these quick fixes, Rick. A question: What I like about Microsoft’s screenshot app is that it automatically generates a filename for each new screenshot. I wonder if paint.net could do the same for new files instead of defaulting to “Unknown”, like “PDN-datetime”. I often use paint.net for screenshots in certain scenarios because it opens so fast, but then I have to manually enter a descriptive filename. It’s not a huge issue, but a bit clumsy and outdated (feels like the original MS Paint) for an application known for its speed and ease-of-use. Thank you for your time.

You did very well not to ignore this problem,
Thank you for the work done
Hi. I just installed paint.net 4.3.2 via its offline installer. My firewall informs that it attempted to access 208.112.63.123:443 at the end of the installation, which resolves to victoriaclarkonline.com. Would you kindly explain what’s going on?
That’s also getpaint.net’s IP address. It’s a shared server. It confused me too when I did an nslookup on the IP, but doing a lookup on getpaint.net will confirm this.
Thanks.
I remember seeing somewhere that pressure sensitivity is a planned upcoming feature. Is that coming soon? Or is it already present and I have missed it?
This was moved to the 4.4 release. Migrating to .NET 5 just became a much higher priority. It’s coming!
So, paintdotnet.exe hanging around in Task Manager after I exited it (From File->Exit) is a bug or a feature? (Quick launch or something).
Definitely a bug. Have you seen it many times, or just once?
Twice so far. I have a Canon scanner plugged in USB and use it frequently (Acquire -> From Scanner of Camera…). Maybe somehow related to this fact? Although, today I’ve scanned several images and paintdotnet.exe did not persist after exiting.
Okay I’ll file a bug and keep an eye on it. Thanks for reporting it!
Hello,
Is the Text Tool editing somehow added into the plan to update or fix it?
Currently modifying text is really uncomfortable at all.
Once we done editing, it then turns into graphics and no more ability to change
Hope this text feature will be improve in the near future.
This is actually a very large project that has to be done after some other large projects. It’s on “the list” but it’s going to be quite awhile.
