Frequently Asked Questions
What size should a Wix hero image be?
Wix recommends 1920x1080 pixels for full-width hero images and background strips. This matches Full HD resolution and ensures crisp display on most desktop screens. Keep file size under 500 KB for best performance.
Does Wix optimize images automatically?
Yes, Wix automatically converts images to WebP format and serves responsive sizes for different devices. However, uploading properly sized images (not too large) helps Wix deliver them faster.
Why is my Wix site loading slowly?
Large, unoptimized images are the most common cause of slow Wix sites. Compress images before uploading, use JPEG instead of PNG for photographs, and avoid uploading images larger than 1920px wide unless necessary.
What formats does Wix support?
Wix supports JPEG, PNG, GIF, WebP, SVG, BMP, and ICO. For photos, use JPEG. For graphics with transparency, use PNG or SVG. Wix automatically serves WebP to supported browsers for better performance.
