Why Resize Images Before Upload?

Properly resizing images helps reduce page size, prevent layout shifts, improve page speed, increase SEO performance, and reduce bandwidth usage. Large unscaled images are one of the most common website performance issues.

Resizing FAQ

Which mode should I use for Instagram?
For Instagram posts, we recommend 1:1 Square (1080x1080) for the main feed or 4:5 Portrait (1080x1350). The portrait format grabs more screen real estate! For Stories and Reels, use 9:16 (1080x1920).
Does reducing quality blur my image?
Lowering quality (e.g., to 80%) mainly removes invisible color data to save file size. It rarely causes visible blur unless you go below 60%. It's great for faster loading websites.
What is 'Cover' vs 'Contain'?
Cover fills the entire canvas (cropping excess). Contain ensures the whole image is visible (adding white space if needed). Stretch warps the image to fit (not recommended).
