Frequently Asked Questions (FAQ)

Does resizing an image reduce its quality?

Making an image smaller (downsizing dimensions) generally maintains the crispness and quality of the photo while reducing the file size. However, stretching a small image into a much larger dimension (upscaling) may cause pixelation or blurriness.

What is the best image size for social media?

It depends on the platform! For Instagram squares, 1080x1080 pixels is ideal. For Facebook link thumbnails, use 1200x628 pixels. You can use our tool to easily type in these exact dimensions and prep your graphics.

Do I need to install any software?

No, this is a completely web-based tool. It works perfectly on Windows, Mac, Linux, iOS, and Android web browsers without installing any external apps or plugins.
