I am not able anymore to download photo's from the photoshop for web on my PC. A few days I was still able to do this.

Hi Mariya, sorry to hear the PNG export stopped working — and good to know the PSD download still works. Let’s first rule out a browser issue, following Adobe’s official troubleshooting steps for Photoshop on the web:

1. Try the export again in a new browser window.
2. 2. Make sure your browser is fully up to date — Photoshop on the web is supported on Chrome and Edge 102 and above (64-bit), and Firefox 111 and above.
3. 3. Clear your browser cache and cookies, then try again.
4. 4. Restart your computer.

Could you also let us know which browser (and version) you’re using, and whether you see any error message when the PNG export fails? If the steps above don’t help, please share that detail and we can dig deeper.
