Sfsym – a command-line tool to export Apple SF Symbols as vector SVG/PDF/PNG.

Technical Positioning

Automates the export of high-fidelity Apple SF Symbols, providing programmatic access for 'agentic design sessions' and saving manual effort. Ensures output matches system rendering, not approximations.

SaaS Insight & Market Implications

This tool addresses a niche but critical developer friction point within the Apple ecosystem: programmatic, high-fidelity access to SF Symbols. Its direct integration with macOS's symbol renderer ensures visual accuracy, essential for consistent design systems and automated asset pipelines. The `--json` output and schema definition align with modern trends towards machine-readable interfaces and agent-driven development workflows. The `data-layer` attribute for CSS retheming further enhances utility for scalable design operations. While specific to Apple, the underlying principle of extracting and manipulating proprietary UI assets programmatically has broader implications for cross-platform design consistency and automated UI development, reducing manual intervention.

Show HN: Sfsym – Export Apple SF Symbols as Vector SVG/PDF/PNG

I found myself reaching for SF Symbols' 'Copy Image As…' quite often during agentic design sessions, so I made a command-line tool that the agent can use by itself. It exports Apple SF Symbols as SVG, PDF, or PNG.The vector paths come directly from macOS's symbol renderer. Internally it reaches a private ivar on NSSymbolImageRep to get the CUINamedVectorGlyph, draws into a CGPDFContext, then walks the PDF content stream back out as SVG `d` commands. The output matches what the system draws, rather than an approximation traced from rasters.A few things about it:- Every subcommand accepts `--json`, and `sfsym schema` returns a machine-readable description of the whole CLI.
- Symbol enumeration reads the OS's Assets.car BOM tree, so the list of 8,300+ names stays current with macOS updates without a version table in the binary.
- Each SVG `` carries a `data-layer` attribute, so you can retheme in CSS without touching geometry.It's been saving me a bunch of clicking. Please let me know if you have any other ideas for it.

any chance for other icon sets? lucide/tabler/material. keeping icons consistent between a web app and ios app is pain when the toolchains dont overlap

> The default format is PDF.Genuine question: what’s your use case for having a single SF Symbols icon as a PDF file? Let alone having that as the default? In my own experience, I’d want SVG nearly every time.

But these are copyright by Apple so are you allowed to use them on your commercial websites and apps?

For those wondering what SF symbols are:https://developer.apple.com/sf-symbols/This is not my iconset of choice, though.

This is great! I found myself asking my AI agents to generate those icons every so often (esp. for websites), so thank you for taking the time to build this.Quick question, are you also planning on supporting animations?
