Open Graph Image Maker
This web app will take image files (jpg, png or webp) and convert them to the ideal size for the Open Graph protocol. It detects the source image file type automatically.
It can create WebP, JPG and PNG files. The source image will be centred, cropped and resized to 1200 x 630 pixels - which is the recommended size. However you can chose a square image if desired, for tall images.
