Create the image. Keep the system

quickthumb turns a visual composition into reusable Python or JSON. Build it once, change the content or assets, and render consistent creative at any scale.

pip install quickthumb

from quickthumb import Canvas

canvas = (
    Canvas.from_aspect_ratio("16:9", base_width=1280)
    .background(color="#F5F5F7")
    .text(
        "Make the message impossible to miss.",
        size=88,
        color="#1D1D1F",
        weight=700,
        position=(80, 180),
        max_width=820,
    )
    .shape(
        "rectangle",
        position=(80, 500),
        width=180,
        height=8,
        color="#0066CC",
    )
)

canvas.render("announcement.png")

The core workflow stays small:

1. Create a Canvas.
2. Add backgrounds, text, images, shapes, SVG, or auto-layout groups.
3. Call render().

Built for creative automation

• Layered by default — compose visuals in the same order people think about them.
• Python or JSON — author directly, generate specs with AI, or template content at scale.
• One source, many formats — render images, animated media, documents, and slide decks.
• Designed to be checked — diagnostics catch common layout and legibility problems before export.

Render wherever the work goes

canvas.render("creative.png")
canvas.render("creative.svg")
canvas.render("creative.html")
canvas.render("creative.pptx")
canvas.render("creative.pdf")
canvas.render("creative.gif")
canvas.render("creative.mp4")

Multi-slide Deck compositions can also render to numbered images, PDF, PPTX, HTML slideshows, GIF, WebM, and narrated MP4.

Some formats use optional dependencies. See Installation and Exporting for the exact setup and format behavior.
