Image Resizer Tool – Resize Images Instantly Without Losing Quality
In today’s digital world, images play a major role in everything we do online. Whether you’re managing a website, posting on social media, creating an eCommerce store, or sending files via email, image size matters a lot. Large image files can slow down websites, take up storage space, and make sharing difficult. That’s where an Image Resizer Tool comes in handy.

10. What’s the difference between resizing and cropping an image?

Use PNG for images with transparency or graphics.
Use WEBP for web optimization — it offers great quality with smaller sizes.
