Polotno SDK lets you build and embed a full template system for images and videos inside your product. Developers can define editable layouts — text, graphics, or video layers — and let users customize them directly on the canvas. Templates are stored and rendered using Polotno’s schema, making them easy to automate, version, or generate programmatically.
Key features
Unified template model
Use a single JSON schema to define templates for both image and video formats. Every layer — text, image, SVG, or video — can be positioned, scaled, and styled programmatically.
Customizable layout elements
Templates can include editable text fields, replaceable images or videos, and locked design components. Developers decide which parts are editable and which remain fixed for brand consistency.
Schema-driven control
Each template is fully defined through the schema, allowing automatic generation, duplication, or population from external data sources. Ideal for dynamic ad creation or AI-assisted workflows.
Multi-format export
Templates can be exported as images, PDFs, GIFs, or MP4 videos. Rendering works locally, via a self-hosted service, or through the Polotno Cloud Rendering API for automation and high-volume workloads.
Layer and asset management
Manage fonts, brand colors, icons, and reusable assets within template definitions. Developers can pre-load brand packs or content libraries to ensure visual consistency.
Automation and AI integration
Connect templates to APIs or AI models to auto-fill content, apply variations, or create thousands of designs programmatically. Each instance is generated through schema manipulation, making it reproducible and scalable.
