.JPG File
What is it?
A JPG (or JPEG) is a compressed image format used for photos and web graphics. It uses lossy compression to keep file sizes small while preserving reasonable visual quality.
How do I open it?
Any image viewer, web browser, or photo editor opens JPG files natively — including the default Photos app on Windows, macOS, iOS, and Android.
Is it safe?
Yes. JPG files only contain image data and cannot run code, so they can't infect your device on their own.
Can I delete it?
Only delete a JPG if you're sure you no longer need the photo — there's no way to recover the exact same file once removed unless you have a backup.
