Resize images for social media
Every platform crops differently, so a photo that looks great in a feed can be cut off in a story. The Quick Sizes panel covers the dimensions people ask for most — Instagram posts and stories, YouTube thumbnails and banners, Facebook and LinkedIn posts, X posts and WhatsApp status images. Pick one and the width and height fill in for you; you can still edit them afterwards.
Supported image formats
- JPG / JPEG
- PNG
- WebP
You can also convert while resizing — load a PNG and save it as JPG or WebP to get a lighter file for the web.
