psd2svg 0.11.0

Convert PSD file to SVG file

PSD2SVG

PSD to SVG converter based on psd-tools.

Features

• Convert PSD files to clean, editable SVG
• Preserve layers and artboards with smart group optimization
• Convert text layers to native SVG text elements (experimental)
  • Arc warp support with SVG textPath
  • Smart font matching with Unicode codepoint-based selection
• Support for most Photoshop blending modes (with approximations for unsupported modes)
• Adjustment layers support (experimental)
• Optional font subsetting and embedding for web optimization (typically 90-95% size reduction)
• Built-in resource limits for security (file size, timeout, layer depth, dimensions)
• Command-line tool and Python API

Installation

pip install psd2svg

Optional Features

# Browser-based rasterization (better SVG 2.0 support)
pip install psd2svg[browser]
playwright install chromium

Quick Start

Command Line

# Basic conversion
psd2svg input.psd output.svg

# With external images
psd2svg input.psd output.svg --image-prefix images/img

Python API

from psd2svg import convert

# Simple conversion with embedded images
convert('input.psd', 'output.svg')

# With external images
convert('input.psd', 'output.svg', image_prefix='images/img')

Advanced Usage

from psd_tools import PSDImage
from psd2svg import SVGDocument

# Load PSD and create SVG document
psdimage = PSDImage.open("input.psd")
document = SVGDocument.from_psd(psdimage)

# Save with options
document.save("output.svg", embed_images=True)

# Embed and subset fonts for web
document.save("output.svg", embed_fonts=True, font_format="woff2")

# Rasterize to PNG
image = document.rasterize()
image.save('output.png')

Known Limitations

• Text rendering: Requires matching system fonts; rendering may differ from Photoshop if fonts are unavailable or substituted
• Text wrapping: Basic support via --text-wrapping-mode foreignobject CLI option or text_wrapping_mode=TextWrappingMode.FOREIGN_OBJECT in Python API (uses <foreignObject>). Note: not supported by ResvgRasterizer, only works in browsers
• Blending modes: Some advanced modes approximated due to CSS spec limitations (Dissolve, Linear Burn/Dodge, Darker/Lighter Color, Vivid/Linear/Pin Light, Hard Mix, Subtract, Divide)
• Gradients: Advanced types not supported (Angle, Reflected, Diamond)
• Filter effects: Bevels, embossing, and satin effects not supported; other effects are approximations
• Adjustment layers: Some not yet implemented (Black & White, Channel Mixer, Color Lookup, Gradient Map, Photo Filter, Selective Color, Vibrance)
• Smart objects: Smart object filters not implemented
• Thread safety: APIs are not thread-safe

Platform Support

All platforms (Linux, macOS, Windows) are fully supported for text conversion and font embedding. Text layer conversion uses a hybrid approach with built-in font mappings (~4,950 fonts) plus platform-specific font resolution.

For detailed font resolution architecture, platform-specific implementation details, and custom font mapping, see the Font Handling documentation and Technical Notes.

Security

psd2svg includes built-in security features for processing untrusted PSD files:

• Resource limits (file size, timeout, layer depth, dimensions)
• Path traversal protection
• Font file validation

For comprehensive security guidance, sandboxing strategies, and production deployment best practices, see the Security Documentation. To report vulnerabilities, see SECURITY.md.
