(And why you should be using them)
Got a file ending in “.png” and not sure what to do with it? No worries, PNG might sound like tech-speak, but it’s actually one of the most practical, powerful, and user-friendly file formats out there. In this quick guide, you’ll learn how to open a PNG file, convert it to other image formats, and understand why this high-quality image format is still the go-to for clean graphics and crisp transparent backgrounds.
Spoiler: it’s not just for screenshots.
What is a PNG File?
A PNG (short for Portable Network Graphics) is your image’s best friend when quality can’t be compromised. It’s the format that keeps things crisp — no matter how many times you open, tweak, or save the file.
Why do people love PNGs? Simple:
- They don’t blur or break down with editing
- They support transparency, so they’re perfect for logos and overlays
- They’re great for detail-heavy images like screenshots, icons, and clean graphics
Originally designed to improve on older formats like GIF, the PNG format became the gold standard for web graphics and design. It skips the flashy animation features but nails what matters most: clarity, control, and consistency — all in a format that plays well with almost every device and app out there.
If you’ve got a screenshot, wallpaper, or design element that needs to look sharp and stay sharp, PNG is the way to go.
