Frequently Asked Questions about image-converter

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert SVG to PNG on macOS for web assets?▼

To convert SVG to PNG on macOS, this Skill rasterizes the SVG using local utilities like rsvg-convert or magick. It checks tool availability at runtime and applies safe fallbacks to produce cross-platform PNG output at your chosen size.

Can I generate ICNS and ICO files for app icons locally on macOS?▼

Yes, you can generate ICNS and ICO files for app icons locally on macOS. This Skill uses built-in utilities like iconutil and magick to create Windows ICO and macOS ICNS assets from your source images without external services.

Does this image conversion approach work without installing extra software on macOS?▼

This image conversion approach works using pre-existing macOS local tools. It requires dependencies like rsvg-convert, magick, sips, iconutil, and qlmanage, performing runtime checks to verify tool availability and provide safe fallbacks if a tool is missing.

What's the best way to batch resize and export images to WebP and PDF on macOS?▼

The best way to resize and export images to WebP and PDF on macOS is using a deterministic command-line workflow. This Skill leverages local utilities like sips and magick to streamline format conversion and resizing for app and website assets.

Why does SVG rasterization fail when rsvg-convert is not installed?▼

SVG rasterization may fail if rsvg-convert is not installed because it is a primary tool for converting SVG files. The Skill checks for rsvg-convert availability and falls back to magick, but if neither is present, the rasterization cannot proceed safely.
