oxipng — Losslessly improve compression of PNG files. More information: <https://manned.org/oxipng>.Compress a PNG file (overwrites the file by default):
oxipng {{path/to/file.png}}Compress a PNG file and save the output to a new file:
oxipng --out {{path/to/output.png}} {{path/to/file.png}}Compress all PNG files in the current directory using multiple threads:
oxipng "*.png"Compress a file with a set optimization level (default is 2):
oxipng {{[-o|--opt]}} {{0|1|2|3|4|5|6|max}} {{path/to/file.png}}Set the PNG interlacing type (
0 removes interlacing, 1 applies Adam7 interlacing, keep preserves existing interlacing; default is 0):oxipng {{[-i|--interlace]}} {{0|1|keep}} {{path/to/file.png}}Perform additional optimization on images with an alpha channel:
oxipng {{[-a|--alpha]}} {{path/to/file.png}}Use the much slower but stronger Zopfli compressor with max optimization:
oxipng {{[-Z|--zopfli]}} {{[-o|--opt]}} max {{path/to/file.png}}Strip all non-critical metadata chunks:
oxipng --strip all {{path/to/file.png}}Code Snippets
