How to open a PNG file?
If you cannot open a PNG file, it is most often due to missing software. Select a program from the list according to your operating system. Then go to the official website of the program developer, download it, and install it on your device.
XnView, ImageJ and Fotor Photo Editor stand out as the preferred programs to manage PNG files effectively. To get the latest version of Adobe Photoshop, open the Adobe website where a universal installer for all operating systems is available.
After setup, the operating system should recognize PNG files and link them with Adobe Photoshop.
Set Adobe Photoshop as the default PNG program
Change Default Program on Mac
- Right click or Control + left click on the desired PNG file;
- Choose "Open in Application" and click "Other";
- Scroll down to the bottom of the window, and there you will find the "Enable" menu. The default selection is "Recommended Programs";
- Choose "All Programs" within this menu and locate Adobe Photoshop. Check the box next to "Always open in app" to set it as the default program.
Set default programs for Windows
- Start by right-clicking on your PNG file, then select the "Open with" option and choose "Choose another app" from the menu that appears;
- In the pop-up window, select the Adobe Photoshop application;
- Check the "Always use this application" checkbox, and then click "OK" to apply the selected application as the default for opening PNG files.
Convert files to and from PNG
If a PNG file is difficult to handle, you might try converting it to formats such as DWG, JPG, JPEG, GIF, MP3 or similar, which may be easier to work with.
Be aware that converting a PNG file may reduce some features, but you can usually revert it to the original format.
Offline conversion tools, like XnView, Adobe Photoshop and IrfanView, provide reliable and high-quality conversion of PNG files.
