Small Mac apps to convert SVG files to PNG, ICNS, and macOS folder icons.
Inutile, donc indispensable
Launch one of the apps, then drop an SVG file to convert it.
Right-click on an SVG file, select Open with, then choose one of the svg2any apps.
| App | Description |
|---|---|
 svg2png |
Convert an SVG file to a PNG image with transparency |
 svg2icns |
Convert an SVG file to a macOS high-resolution icon |
 svg2folder |
Set the containing folder icon to the SVG image |
 svg2svg |
Resize an SVG to 1024 x 1024 |
Convert an SVG file to a PNG image with transparency, perfect for social networks that don't support SVGs.
The resulting PNG file is compressed using the slow but efficient Zopfli algorithm for images up to 1024 pixels, and the faster but less efficient zlib algorithm for larger images.
Important Images up to 1024 pixel are compressed using Zopfli, which is very slow. It takes 2~3 minutes on a recent MacBook Pro M1 for a simple image. More complex images with lots of details, or less capable CPUs, will take way more time.
Convert an SVG file to a macOS high-resolution icon.
Set the containing folder icon to the SVG image.
Resize an SVG to 1024 x 1024.
The resulting SVG will not be optimized, it's just a simple resize.
It is recommended to optimize the resulting SVG with svgo, an online version is available at SVGOMG.
- Some SVGs work best when only the
viewBoxattribute is set. - On macOS, the finder will show a better icon preview when the width and height attributes are not present.
Original SVG file:
<svg width="1024" height="1024" [...]>Better:
<svg viewBox="0 0 1024 1024" [...]>
- ICNS file are not compressed with
oxipngsinceiconutilrecompress them anyway. - Compressing each PNG files before packing them with
iconutilwill result in larger ICNS files.
Each app create a unique log file in ~/Library/Logs/cyann.
Why this?
- I like SVG files: they are tiny, can be optimized a lot, and look good at any resolution.
- I also like my folder icons to be more visually descriptive as it makes me more productive.
- However macOS can't use SVGs for icons, it works only with ICNS.
- Switching to the console to run a script breaks my flow when I'm managing files and folders with Finder.
- Compiling the binaries is a PITA when dealing with C code
on legacy hardware (try to
brew install librsvg), Rust works better.
This little project should help me with Ally, Ystorian's inventory command line tool written in Rust:
- Provide some kind of limited GUI.
- Bundled in macOS apps that are more user-friendly than command line tools.
- With universal binaries to support the modern arm64 architecture (Apple
- Silicon) as well as the legacy x64 (Intel).
- Signed and notarized.
- Available in the App Store for easier distribution.
- Experiment to find the best app sandboxing and hardening options.
- And understand which open source license works best with app distribution in the App Store.
The binaries that used to be included were built from these repositories:
- rsvg-convert (LGPL)
- oxipng (MIT)
- Platypus (BSD)
The rest is AGPL3, feel free to ask for another license if needed.
svg2any depends on these binaries to build the apps:
- Build the macOS .app: Platypus
- Convert SVG to PNG files: rsvg-convert
- Compress PNG files: oxipng
The command line tool for Platypus can be installed with Homebrew:
brew install platypusNotes:
- To help build universal apps, the compiled binaries
librsvgandoxipng, for x86_64 (Intel) and arm64 (Apple Silicon since M1), used to be present in this repository. - The build script optimizes the NIB in the bundles with the
optimize-nibparameter. - This requires Xcode to be installed and configured.
Build the apps with Platypus:
./build.shSee rustup.rs
Add and update the 2 supported targets:
rustup target add aarch64-apple-darwin
rustup target add x86_64-apple-darwinbrew install cairo pkg-config pango gdk-pixbufUse these commands to compile the binaries and combine them to get the universal binaries.
mkdir vendor
mkdir bin
git -C "vendor" clone https://gitlab.gnome.org/GNOME/librsvg.git
git -C "vendor/librsvg" pull

lipo vendor/librsvg/target/aarch64-apple-darwin/release/rsvg-convert vendor/librsvg/target/x86_64-apple-darwin/release/rsvg-convert -create -output bin/rsvg-convertThe generated rsvg-convert universal binary can then be copied to svg2any/
git clone https://github.com/shssoichiro/oxipng.git
cd oxipng

The binaries must not have dependencies on locally installed libraries.
The otool command should only list path in /usr/lib and /System/Library.
otool -l rsvg-convert | grep "name /"otool -l oxipng | grep "name /"

xcode-select: error: tool 'ibtool' requires Xcode, but active developer
directory '/Library/Developer/CommandLineTools' is a command line tools instance
Solution: Launch Xcode, open the Settings pane, select the Locations tab and ensure Command Line Tools is not empty.
