Swiftask transforms your HTML/CSS templates into ready-to-post images. Generate personalized visuals at scale, instantly.

Result:

Eliminate manual design tasks. Produce consistent, professional visuals in seconds.

Manual design bottleneck is slowing down your social strategy

Producing banners for every campaign, product, or blog post is a massive time sink. Marketing teams juggle design tools, copy-pasting, and format adjustments, significantly slowing down content publication.

Main negative impacts:

  • Creative bottleneck: The need for personalized visuals exceeds your design team's capacity, leading to frustrating publication delays.
  • Visual inconsistency: Manual adjustments across different tools lead to brand guideline violations and a fragmented brand image.
  • High operational costs: Time spent by experts on simple repetitive design tasks represents a significant hidden cost for your business.

Swiftask automates production using the HTML/CSS to Image connector. You code your template once, and the AI automatically generates visuals for every new content item.

BEFORE / AFTER

What changes with Swiftask

The traditional way

A marketer prepares a new post. They open a design tool, find the template, edit the text, adjust the image, export to PNG, then download the file. A repetitive task taking 15 minutes per visual.

The Swiftask approach

As soon as a new post is ready, Swiftask pulls the data, injects it into your HTML/CSS template, and generates the final image automatically. Zero clicks, zero manual design.

Automate your visuals in 4 simple steps

STEP 1 : Define your HTML/CSS template

Use your web skills to build a flexible template. Include variables for text, images, and colors.

STEP 2 : Configure the Swiftask connector

Connect the HTML/CSS to Image module in Swiftask and import your code. Swiftask becomes your rendering engine.

STEP 3 : Set the generation trigger

Link the generation to an event: blog post publication, new product, or database update.

STEP 4 : Automate the workflow

The generated image is automatically stored or sent to your social media publishing tools.

Rendering power for your banners

Swiftask handles dynamic rendering: custom fonts, dynamic images, and responsive design for various formats (LinkedIn, Twitter, Instagram).

  • Target connector: The agent performs the right actions in html/css to image based on event context.
  • Automated actions: High-resolution conversion (PNG/JPEG). Full CSS properties support (Flexbox, Grid). Dynamic data injection via API. Ultra-fast rendering.
  • Native governance: You keep full control over aesthetics via your code while benefiting from Swiftask's automation power.

Each action is contextualized and executed automatically at the right time.

Each Swiftask agent uses a dedicated identity (e.g. agent-html/css-to-image@swiftask.ai ). You keep full visibility on every action and every sent message.

Key takeaway: The agent automates repetitive decisions and leaves high-value actions to your teams.
