When a reader shares an article URL on social media, the open graph card is the single most important factor determining click-through rates. Search crawlers and social bots specifically check for an image that complies with the 1.91:1 aspect ratio. At 1200x630 pixels, your headline and branding remain razor-sharp even on 4K monitors and mobile OLED screens.
Unlike other online image converters that transfer your confidential documents, family pictures, and signatures to remote cloud servers, this toolkit runs WebAssembly and HTML5 Canvas algorithms entirely inside your browser sandbox. Your files never leave your device.
