🧩 Quick file helper

Which app opens this file? (What Opens File Extension)

Type a file ending (like .heic or .7z) → choose your device (optional) → get trusted app suggestions → open it safely. Nothing is uploaded — it runs in your browser.

Tip: include the dot or not — both work. If you have a filename, type just the ending (e.g., holiday.heic → .heic).

If you choose a device, we’ll show that list first.

Helpful when the ending is uncommon or risky.

Safety note: be extra careful with installers and scripts (like .exe, .msi, .apk, .deb, .rpm, .appimage, .bat, .js, .sh). This tool suggests reputable apps, but it can’t verify whether a specific file is safe.
