Postcraft Studio is a free design editor for social media images. Start from a template or a blank page at the exact size each platform wants, then export PNG, JPG, WebP or AVIF. It runs in your browser with no account, and your photos never leave your device.
Runs entirely in your browser
Postcraft Studio is a design editor for social media images that runs entirely in your browser. You choose what you are making — an Instagram post, a story, a Pinterest pin, a YouTube thumbnail or a custom size — and start either from a blank page at that exact size or from one of more than 1,500 templates.
Everything on the page is editable: text with fonts and highlights, shapes, icons, photos with crops, filters and masks, and colours through a palette that keeps text readable. A legibility check flags text that will be hard to read, and the editor shows each platform’s safe zones so buttons and captions do not cover your words.
One design can become many: Magic Resize turns a post into a story, a pin or a banner, re-arranging the layout for the new shape rather than just stretching it. When you are done, export PNG, JPG, WebP or AVIF, at up to 8K on desktop, or download several sizes together as a ZIP.
