Converting Fonts for the Web Revision as of Saturday, 9 April 2022 at 18:21 UTC

Encode and Decode

Encode

function dataurl() {
    local MIMETYPE
    MIMETYPE=$(file -b --mime-type "$1")

    if [[ $MIMETYPE == text/* ]]; then
        MIMETYPE="${MIMETYPE};charset=utf-8";
    fi
    echo "data:${MIMETYPE};base64,$(openssl base64 -in "$1" | tr -d '\n')";
}

Decode

#!/bin/bash

ENCODED_FILE=$1
sed 's/data:application\/font-woff;base64,//g' "$ENCODED_FILE" | base64 -D > "${ENCODED_FILE%%.*}.woff"

WOFF, WOFF2, TTF, OTF, and SVG

Install FontForge (on Homebrew) and then save this as a script (convert.pe) and make it executable. Now you can convert whatever you’d like.

Open($1)

Generate($1:r + ".ttf")
Generate($1:r + ".otf")
Generate($1:r + ".svg")

Run with

fontforge -script name_of_script font.woff

You can also use FontSquirrel’s excellent Online Generator.

Deprecated Stuff

EOT (Deprecated Format)

Install ttf2eot via Brew and then

ttf2eot Inconsolata.otf > Inconsolata.eot

For a bunch of files,

for f in *.otf; do ttf2eot $f > ${f%".otf"}.eot; done

Utilities

Install this via Homebrew and convert away. It installs this script and a bunch of dependencies.
