font-converter COMMAND [ARGS]
All font-converter subcommands process files in the given path. The INPUT_PATH argument can be a single font file or a folder containing one or more fonts. In case a directory is passed as INPUT_PATH, all fonts stored in it will be processed.
The -out, -output-dir, --recalc-timestamp and --no-overwrite options can be used in all subcommands, unless
otherwise specified.
The directory where the converted files are to be saved. If output_dir is not specified, files are saved to the
source folder. If output_dir doesn't exist, it will be automatically created.
By default, original head.modified value is kept when a font is saved. Use this switch to set head.modified
timestamp to current time.
By default, converted files are overwritten. Use this switch to save them to a new file (numbers are appended at the end of file name, so that Times-Bold.otf becomes TimesBold#1.otf).
Converts SFNT fonts (TTF or OTF) to web fonts (WOFF and WOFF2).
Usage:
font-converter ft2wf [OPTIONS] INPUT_PATH
Options:
-f, --flavor [woff|woff2] By default, the script converts SFNT fonts
(TrueType or OpenType) both to woff and woff2
flavored web fonts. Use this option to create
only woff (--flavor woff) or woff2 (--flavor
woff2) files.
-out, --output-dir DIRECTORY Specify the directory where output files are
to be saved. If output_dir doesn't exist, will
be created. If not specified, files are saved
to the same folder.
--recalc-timestamp Keep the original font 'modified' timestamp
(head.modified) or set it to current time. By
default, original timestamp is kept.
--no-overwrite Overwrite existing output files or save them
to a new file (numbers are appended at the end
of file name). By default, files are
overwritten.
--help Show this message and exit.
Converts fonts from CFF to TrueType format.
Usage:
font-converter otf2ttf [OPTIONS] INPUT_PATH
Options:
-out, --output-dir DIRECTORY Specify the directory where output files are
to be saved. If output_dir doesn't exist, will
be created. If not specified, files are saved
to the same folder.
--recalc-timestamp Keep the original font 'modified' timestamp
(head.modified) or set it to current time. By
default, original timestamp is kept.
--no-overwrite Overwrite existing output files or save them
to a new file (numbers are appended at the end
of file name). By default, files are
overwritten.
--help Show this message and exit.
Extracts each font from a TTC file, and saves it as a TTF or OTF file.
Usage
font-converter ttc2sfnt [OPTIONS] INPUT_PATH
Options:
-out, --output-dir DIRECTORY Specify the directory where output files are
to be saved. If output_dir doesn't exist, will
be created. If not specified, files are saved
to the same folder.
--recalc-timestamp Keep the original font 'modified' timestamp
(head.modified) or set it to current time. By
default, original timestamp is kept.
--no-overwrite Overwrite existing output files or save them
to a new file (numbers are appended at the end
of file name). By default, files are
overwritten.
--help Show this message and exit.
Converts fonts from TrueType to CFF format.
Usage:
font-converter ttf2otf [OPTIONS] INPUT_PATH
Options
-t, --tolerance FLOAT RANGE Conversion tolerance (0-5, default 1). Low
tolerance adds more points but keeps shapes.
High tolerance adds few points but may change
shape. [0<=x<=5]
--safe Sometimes Qu2CuPen may fail or produce
distorted outlines. Most of times, using '--
safe' will prevent errors by converting the
source TTF font to a temporary OTF built using
T2CharstringsPen, and then reconverting it to
a temporary TTF font. This last one will be
used for TTF to OTF conversion instead of the
source TTF file. This is slower and produces
slightly bigger files, but is safer.
--keep-glyphs Doesn't remove 'NULL' and 'CR' glyphs from the
output font.
--no-subr Turn off subroutinization of converted fonts.
-out, --output-dir DIRECTORY Specify the directory where output files are
to be saved. If output_dir doesn't exist, will
be created. If not specified, files are saved
to the same folder.
--recalc-timestamp Keep the original font 'modified' timestamp
(head.modified) or set it to current time. By
default, original timestamp is kept.
--no-overwrite Overwrite existing output files or save them
to a new file (numbers are appended at the end
of file name). By default, files are
overwritten.
--help Show this message and exit.
Exports static instances from variable fonts.
Usage:
font-converter var2static [OPTIONS] INPUT_PATH
Options:
-s, --select-instance By default, the script exports all named
instances. Use this option to select custom
axis values for a single instance.
--no-cleanup By default, STAT table is dropped and axis
nameIDs are deleted from name table. Use --no-
cleanup to keep STAT table and prevent axis
nameIDs to be deleted from name table.
--update-name-table Tries to update the instantiated font's `name`
table. Input font must have a STAT table with
Axis Value Tables.
-out, --output-dir DIRECTORY Specify the directory where output files are
to be saved. If output_dir doesn't exist, will
be created. If not specified, files are saved
to the same folder.
--recalc-timestamp Keep the original font 'modified' timestamp
(head.modified) or set it to current time. By
default, original timestamp is kept.
--no-overwrite Overwrite existing output files or save them
to a new file (numbers are appended at the end
of file name). By default, files are
overwritten.
--help Show this message and exit.
Converts web fonts (WOFF and WOFF2) to SFNT fonts (TTF or OTF).
Usage:
font-converter wf2ft [OPTIONS] INPUT_PATH
Options:
-f, --flavor [woff|woff2] By default, the script converts both woff and
woff2 flavored web fonts to SFNT fonts
(TrueType or OpenType). Use this option to
convert only woff or woff2 flavored web fonts.
-d, --delete-source-file Deletes the source files after conversion.
-out, --output-dir DIRECTORY Specify the directory where output files are
to be saved. If output_dir doesn't exist, will
be created. If not specified, files are saved
to the same folder.
--recalc-timestamp Keep the original font 'modified' timestamp
(head.modified) or set it to current time. By
default, original timestamp is kept.
--no-overwrite Overwrite existing output files or save them
to a new file (numbers are appended at the end
of file name). By default, files are
overwritten.
--help Show this message and exit.
