Social Media Images: WebP for Your Site, JPEG for the Networks

Social networks recompress whatever you upload. Your website should not. Use their native JPEG/PNG specs for posts, and convert the same creatives to WebP for your blog, campaign pages and link-in-bio site.

Two outputs from one design

Export from Canva/Figma once at a high-quality PNG or JPEG. Upload that to Instagram. Convert a copy to WebP 1080–1600 px for the website.

Why it matters

Link-in-bio pages are real websites with LCP.
Republished Instagram grids on a site are often uncompressed dumps.
You do not control Meta's encoder; you do control yours.

How to do it

Keep a social-masters folder.
Convert website copies at 1080–1600 px / 80%.
Do not replace the file you upload to Instagram with WebP unless the app accepts it (it usually wants JPEG).

Settings that work

Feed 1080 px. Stories 1080×1920 — convert if they appear on the web; for the app, follow the network.

Put it into practice
