Set the optimization level preset.

The default level
|

.B 2

is quite fast and provides good compression.

Lower levels are faster, higher levels provide better compression,

though with increasingly diminishing returns.

(files with \(lq.png\(rq or \(lq.apng\(rq extension).
|

.TP

Write output file(s) to

is one of:

.RS

.TP
|

.B safe

Strip all metadata except in the comma-separated list

.TP
|
||||
.BR \-a ,\ \-\-alpha
|
||||
Perform additional optimization on images with an alpha channel,
|
||||
by altering the color values of fully transparent pixels.
|
||||
This is generally recommended for better compression,
|
||||
but take care as while this is \(lqvisually lossless\(rq,
|
||||
it is technically a lossy transformation
|
||||
and may be unsuitable for some applications.
|
||||
.TP
|
||||
.BR \-i ,\ \-\-interlace\ \fItype
|
||||
Set the PNG interlacing type, where
|

.I type

is one of:

.RS
|

.TP
|

.B 0

Apply Adam7 interlacing on all images that are processed
|

.TP
|

.B keep
|

Keep the existing interlacing type of each image
|
||||
.RE
|
||||
.IP
|
||||
Note that interlacing can add 25-50% to the size of an optimized image.
|
||||
Only use it if you believe the benefits outweigh the costs for your use case.
|
||||
.IP
|
||||
[default:
|
||||
.BR 0 ]
|
||||
.TP
|
||||
.B \-\-scale16
|
||||
Forcibly reduce images with 16 bits per channel to 8 bits per channel.
|
||||
This is a lossy operation but can provide significant savings
|
||||
when you have no need for higher depth.
|
||||
Reduction is performed by scaling the values such that,
|
||||
e.g. 0x00FF is reduced to 0x01 rather than 0x00.
|
||||
.IP
|
||||
Without this flag, 16-bit images will only be reduced in depth
|
||||
if it can be done losslessly.

.TP
|

.BR \-v ,\ \-\-verbose ...
|

Run in verbose mode (use twice to increase verbosity)

Run in quiet mode

.TP
|

.BR \-f ,\ \-\-filers\ \fIlist
|

Perform compression trials with each of the given filter types.
|
||||
You can specify a comma-separated list, or a range of values.
|
||||
E.g.\:
|
||||
.B \-f\ 0\-3
|
||||
is the same as
|

.BR \-f\ 0,1,2,3 .

Lowest count of distinct bigrams
|

.TP
|

.B 8\ \[rA] BigEnt
|
||||
Highest Shannon entropy of bigrams
|

.TP

|

Smallest compressed size (slow)

.RE

.IP
|

The default value depends on the optimization level preset.
|
||||
.TP
|
||||
.B \-\-fast
|
||||
Perform a fast compression evaluation of each enabled filter,
|
||||
followed by a single main compression trial of the best result.
|
||||
Recommended if you have more filters enabled than CPU cores.
|
||||
.TP
|
||||
.B \-\-zc\ \fIlevel
|
||||
Deflate compression level (1\-12) for main compression trials.
|
||||
The levels here are defined by the libdeflate compression library.
|

.IP
|

The default value depends on the optimization level preset.

|

.TP
|
||||
.B \-\-nc

.TP
|
||||
.B \-\-np
|

Do not change color palette
|

.TP
|
||||
.B \-\-ng
|
||||
Do not change to or from grayscale
|
||||
.TP
|
||||
.B \-\-nx
|
||||
Do not perform any transformations and do not deinterlace by default.
|
||||
.TP
|
||||
.B \-\-nz
|
||||
Do not recompress IDAT unless required due to transformations.
|
||||
Recompression of other compressed chunks (such as iCCP) will also be disabled.
|
||||
Note that the combination of
|
||||
.B \-\-nx
|
||||
and
|
||||
.B \-\-nz
|
||||
will fully disable all optimization.
|
||||
.TP
|
||||
.B \-\-fix
|
||||
Do not perform checksum validation of PNG chunks.
|
||||
This may allow some files with errors to be processed successfully.
|
||||
.TP
|
||||
.B \-\-force
|
||||
Write the output even if it is larger than the input
|
||||
.TP
|
||||
.BR \-Z ,\ \-\-zopfli
|
||||
Use the much slower but stronger Zopfli compressor
|
||||
for main compression trials.
|
||||
Recommended use is with
|
||||
.B \-o\ max
|
||||
and
|
||||
.BR \-\-fast .
|
||||
.TP
|
||||
.B \-\-timeout\ \fIsecs
|
||||
Maximum amount of time, in seconds, to spend on optimizations.
|
||||
Oxipng will check the timeout
|
||||
before each transformation or compression trial,
|
||||
and will stop trying to optimize the file if the timeout is exceeded.
|
||||
Note that this does not cut short any operations that are already in progress,
|
||||
so it is currently of limited effectiveness
|
||||
for large files with high compression levels.
|
||||
.TP
|
||||
.BR \-t ,\ \-\-threads\ \fInum
|
||||
Set number of threads to use
|
||||
[default: num CPU cores]

Print help (see a summary with

.BR \-h )
