Try the free planPrivacy, since we're a privacy-first company: this page uses your browser's canvas to crop and export — no upload, no server, no storage. Close the tab and everything is gone. Sizes follow our verified 2026 image-size reference (center-crop "cover" fit; for full art-direction control, crop by hand in your editor). Exports are high-quality JPEG except Stories/vertical, which export as PNG when the source has transparency.
