In plain English

ImageAutoPNG is a small Windows tool for people who are not particularly technical, built to solve one annoying problem. Modern phones often save photos as .heic or .webp files, formats that many older programs and websites do not open properly. This tool sits quietly in the Windows system tray and watches a folder you choose, the Downloads folder by default, and automatically converts any new .webp.heic, or .heif image it sees into a plain .png file. There is nothing to configure to get started beyond picking the folder to watch. The tray icon is the only visible part of the program while it runs. Conversion happens instantly when a matching file appears, and you can choose whether the original file is deleted after conversion. The tool can also be set to start automatically with Windows and installs without needing administrator rights, so it fits alongside other apps on a shared or work computer. It uninstalls cleanly through the normal Windows Settings menu like any other app. Because the installer is not digitally signed by a paid certificate, Windows SmartScreen may show a warning calling it an "Unknown publisher" the first time you run it. The README explains this is expected for small, independently made free tools, and you can continue by choosing "More info" then "Run anyway." For anyone who wants to build it themselves, the source is Python based and requires Python 3.10 or newer. After installing the listed requirements, running the main script starts the app, and a separate build script packages it into an installer executable. The tool keeps a small configuration file and a log of conversions in a hidden folder under your user profile. All image conversion happens on your own computer. Nothing is uploaded anywhere, no account is required, and no usage data is collected. It is released under the MIT license, and the author accepts optional tips through PayPal, though none are required to use the tool.
