A full design suite that never phones home

Design Studio gives you the core of a pro graphics editor — canvas presets for every social platform, genuinely designed templates, draggable text, shapes, icons and your own images, with smart magenta snap guides, rotation, layering, opacity and shadows. Undo as much as you like, auto-save keeps your work safe in this browser, and you can export crisp PNG (1× or 2×, optionally transparent) or quality-controlled JPG, plus save the whole project as JSON to reopen later. Completely free, no watermark, no account, works offline.
