Pro tip

Pre-optimizing images before uploading to a platform gives you more control than relying on the platform's automatic (and often aggressive) compression.

Frequently Asked Questions

3 questions answered

What is 300×300 pixels used for?

300×300px is used for product thumbnails on e-commerce sites, email newsletter images, LinkedIn and social media profile pictures, and many web form upload requirements. At 96 DPI it measures roughly 3.1 inches square — a common small print size too.

What resolution is 300×300 pixels?

At the standard screen resolution of 96 DPI, 300×300px is about 3.1×3.1 inches. At 300 DPI (print resolution), it would measure 1×1 inch on paper. For web use, pixel dimensions are what matter — not DPI.

How do I resize without losing quality?

Always downscale from a larger original rather than upscaling a small image. Use PNG for graphics with sharp edges, and use JPG at 85% quality for photos. The Image Resizer uses bicubic resampling to minimise softness during resizing.
