SVG to PNG Converter - Replicate Cog

A high-quality SVG to PNG converter packaged as a Replicate model using Cog.

Features

  • Convert SVG files to high-resolution PNG images
  • Adjustable output resolution (width, height, or scale factor)
  • Configurable DPI (72-600)
  • Transparent or custom background colors
  • Optimized PNG output
  • Beautiful progress bars and real-time feedback
  • Detailed conversion analytics and summaries
  • Rich formatted logs with emoji indicators
  • Performance metrics and file size tracking

Setup

Prerequisites

  1. Install Docker and ensure it’s running
  2. Install Cog:
sudo curl -o /usr/local/bin/cog -L https://github.com/replicate/cog/releases/latest/download/cog_`uname -s`_`uname -m`
sudo chmod +x /usr/local/bin/cog

Files

  • cog.yaml - Defines dependencies and environment
  • predict.py - Model prediction interface

Local Testing

Test the model locally with Cog:

# Basic conversion
cog predict -i svg_file=@input.svg

# Scale by 2x
cog predict -i svg_file=@input.svg -i scale=2.0

# Specific dimensions
cog predict -i svg_file=@input.svg -i width=2000 -i height=2000

# High DPI with white background
cog predict -i svg_file=@input.svg -i dpi=300 -i background_color="#FFFFFF"

# Large scale, high DPI for print
cog predict -i svg_file=@input.svg -i scale=4.0 -i dpi=300

API Usage

Via our model, you can use the Python client:

import replicate

output = replicate.run(
    "unityaisolutions/svg-to-png:latest",
    input={
        "svg_file": open("logo.svg", "rb"),
        "scale": 3.0,
        "dpi": 300,
        "background_color": "transparent"
    }
)

# Save the output
with open("output.png", "wb") as f:
    f.write(output.read())

Input Parameters

Parameter Type Description Default
svg_file File SVG file to convert Required
width Integer Output width in pixels (1-10000) SVG width
height Integer Output height in pixels (1-10000) SVG height
scale Float Scale factor (0.1-10.0) - overrides width/height None
dpi Integer Rendering DPI (72-600) 96
background_color String Background color hex or ‘transparent’ transparent

Examples

Create social media graphics:

cog predict -i svg_file=@logo.svg -i width=1200 -i height=630

High-res print ready:

cog predict -i svg_file=@design.svg -i scale=5.0 -i dpi=300

Icon generation:

cog predict -i svg_file=@icon.svg -i width=512 -i height=512

Notes

  • The model uses CairoSVG for rendering, which provides high-quality output
  • For best results with transparency, use PNG format
  • Maximum dimensions are capped at 10000x10000 pixels
  • Scale factors above 5x may result in very large files
