ImageAutoPNG

Watches a folder and silently converts .webp & .heic to .png

Free for Windows · by heyjmo

What it does

ImageAutoPNG sits in the system tray and watches your Downloads folder (or any folder you choose). When a .webp, .heic, or .heif image appears, it converts it to PNG in the background—no popups, no browser extension.

System tray only (no main window clutter)
Per-user install — no administrator password
Optional “start with Windows” and delete originals after convert
Runs entirely on your PC — files are not uploaded anywhere

Download for Windows Source on GitHub Donate (optional)

Windows SmartScreen: Because this free tool is not code-signed, Windows may say “Windows protected your PC.” Click More info, then Run anyway. That is normal for small free software from independent authors.

Install

Download ImageAutoPNG-Setup.exe
If Windows blocks it: Properties → Unblock (if shown), then run
Choose a folder (default is fine) and click Install
Find the tray icon — right-click for options

Privacy

Conversion happens locally. The app only reads/writes image files in the folder you choose. Settings live under your user profile (.imageautopng). There is no account and no telemetry.
