Image Optimizer\n\nOptimize all PNG, JPG images from directories.\n\n## Pull image\n\n```bash\ndocker pull luizeof/image-optimizer\n```\n\n## Source directory\n\nThis container creates a volume at `/source`, so you can mount a local directory to this remote directory and access any file within.\n\n***If OptiPNG can optimize the input file it will be overwritten with the optimized one.***\n\n## Run\n```\n$ docker run luizeof/image-optimzer -help\n\nOptiPNG 0.6.4: Advanced PNG optimizer.\nCopyright (C) 2001-2010 Cosmin Truta.\n\nSynopsis:\n optipng [options] files ...\nFiles:\n Image files of type: PNG, BMP, GIF, PNM or TIFF\nBasic options:\n -?, -h, -help show this help\n -o optimization level (0-7) default 2\n -v verbose mode / show copyright and version info\nGeneral options:\n -fix enable error recovery\n -force enforce writing of a new output file\n -keep keep a backup of the modified files\n -preserve preserve file attributes if possible\n -quiet quiet mode\n -simulate simulation mode\n -snip cut one image out of multi-image or animation files\n -out write output file to \n -dir write output file(s) to \n -log log messages to \n -- stop option switch parsing\nOptimization options:\n -f PNG delta filters (0-5) default 0,5\n -i PNG interlace type (0-1) default \n -zc zlib compression levels (1-9) default 9\n -zm zlib memory levels (1-9) default 8\n -zs zlib compression strategies (0-3) default 0-3\n -zw zlib window size (32k,16k,8k,4k,2k,1k,512,256)\n -full produce a full report on IDAT (might reduce speed)\n -nb no bit depth reduction\n -nc no color type reduction\n -np no palette reduction\n -nx no reductions\n -nz no IDAT recoding\nOptimization details:\n The optimization level presets\n -o0 <=> -o1 -nx -nz\n -o1 <=> [use the libpng heuristics] (1 trial)\n -o2 <=> -zc9 -zm8 -zs0-3 -f0,5 (8 trials)\n -o3 <=> -zc9 -zm8-9 -zs0-3 -f0,5 (16 trials)\n -o4 <=> -zc9 -zm8 -zs0-3 -f0-5 (24 trials)\n -o5 <=> -zc9 -zm8-9 -zs0-3 -f0-5 (48 trials)\n -o6 <=> -zc1-9 -zm8 -zs0-3 -f0-5 (120 trials)\n -o7 <=> -zc1-9 -zm8-9 -zs0-3 -f0-5 (240 trials)\n The libpng heuristics\n -o1 <=> -zc9 -zm8 -zs0 -f0 (if PLTE is present)\n -o1 <=> -zc9 -zm8 -zs1 -f5 (if PLTE is not present)\n The most exhaustive search (not generally recommended)\n [no preset] -zc1-9 -zm1-9 -zs0-3 -f0-5 (1080 trials)\nExamples:\n optipng file.png (default speed)\n optipng -o5 file.png (moderately slow)\n optipng -o7 file.png (very slow)\n optipng -i1 -o7 -v -full -sim experiment.png\n``` \n\n### Optimize all images in current folder\nBy default this image will compress with `-quiet -o7 *.png` and as such will optimize all images with the best optimization level.\n\n```\n$ docker run -v /local-path-to-image:/source luizeof/image-optimizer -quiet -o7 *.png\n```\n\n### Recursivley optimize all images\nThe following command finds all images in the current folder (`find...`), mounts it to the Docker volume (`-v ...`) and optimizes the image with the best optimization level (`-o7`).\n```\n$ find . -name \"*.png\" | xargs docker run -t -v `pwd`:/source luizeof/image-optimizer -o7\n```\n","has_starred","hub_user","immutable_tags_settings",{"_71":11,"_72":73},"enabled","rules",[74],".*","is_automated","permissions",{"_78":17,"_79":11,"_80":11},"read","write","admin","user","storage_size",33431053,"orgData","recentTags",[87,125],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":96,"_46":114,"_115":90,"_116":29,"_117":52,"_53":118,"_119":120,"_121":105,"_122":114,"_123":62,"_124":17},"content_type","creator",2123474,"full_size",32896702,"id",46972891,"images",[97],{"_98":99,"_100":101,"_102":103,"_104":105,"_106":107,"_108":109,"_110":103,"_111":-5,"_112":92,"_59":62,"_113":-5},"architecture","amd64","digest","sha256:288d31b86ddd5941c242d60b7fcc1ebc8d7aaf6a4fc5491b9b409b2312361a3c","features","","last_pulled","2026-09-22T02:11:10.482967972Z","last_pushed","2019-02-14T19:31:48Z","os","linux","os_features","os_version","size","variant","2019-02-14T19:31:47.06169Z","last_updater","last_updater_username","media_type","latest","repository",6691569,"tag_last_pulled","tag_last_pushed","tag_status","v2",{"_88":40,"_89":90,"_91":126,"_93":127,"_95":128,"_46":133,"_115":90,"_116":29,"_117":52,"_53":134,"_119":120,"_121":131,"_122":133,"_123":62,"_124":17},32896700,46973420,[129],{"_98":99,"_100":130,"_102":103,"_104":131,"_106":132,"_108":109,"_110":103,"_111":-5,"_112":126,"_59":62,"_113":-5},"sha256:5622b7024387ecbc647e746394248228a4da3a617772fc1fa9cab7176cfc7338","2026-09-05T19:37:00.384962665Z","2019-02-14T19:35:40Z","2019-02-14T19:35:39.180659Z","0.9.0","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","showSbxLogoOverride","sbxTrademarkText","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_34":146,"_153":154,"_142":167,"_168":11},{"_36":147,"_38":148,"_41":42,"_43":44,"_45":11,"_46":47,"_48":49,"_50":149,"_53":31,"_28":29,"_54":55,"_56":40,"_57":58,"_59":60,"_61":62,"_63":-5,"_64":58,"_65":66,"_67":11,"_68":29,"_69":150,"_75":11,"_76":152,"_81":29,"_82":83},[],[40],[52],{"_71":11,"_72":151},[74],{"_78":17,"_79":11,"_80":11},"tags",{"_155":156,"_157":-5,"_158":-5,"_159":160},"count",2,"next","previous","results",[161,164],{"_88":40,"_89":90,"_91":126,"_93":127,"_95":162,"_46":133,"_115":90,"_116":29,"_117":52,"_53":134,"_119":120,"_121":131,"_122":133,"_123":62,"_124":17},[163],{"_98":99,"_100":130,"_102":103,"_104":131,"_106":132,"_108":109,"_110":103,"_111":-5,"_112":126,"_59":62,"_113":-5},{"_88":40,"_89":90,"_91":92,"_93":94,"_95":165,"_46":114,"_115":90,"_116":29,"_117":52,"_53":118,"_119":120,"_121":105,"_122":114,"_123":62,"_124":17},[166],{"_98":99,"_100":101,"_102":103,"_104":105,"_106":107,"_108":109,"_110":103,"_111":-5,"_112":92,"_59":62,"_113":-5},[],"canDeleteTags","actionData","errors"]
