It focuses on lossless Huffman-table optimization and optional lossy recompression controlled by quality or target-size flags. ### 项目历史 The upstream README records copyright years beginning in 1996 and lists v1.0 as the first public release. The project was built around IJG libjpeg, with compatibility notes for libjpeg-turbo and mozjpeg, and it stayed close to the Unix tradition of a small binary that rewrites files in place unless directed otherwise. The 1.2 and 1.3 series added metadata preservation and stripping controls, GNU autoconf support, progressive JPEG support, target-size compression, and better cross-platform handling. The 1.4 and 1.5 series added stdin/stdout workflows, parallel workers, safer marker handling, fuzzing integration, CI-built binaries, and options such as `--retry`, `--save-extra`, and `--auto-mode`. ### 采用历史 jpegoptim became a standard packaging target because web developers, image pipelines, and static-site build scripts needed a scriptable way to reduce JPEG size without changing formats. Its presence across Homebrew, Debian, Fedora, MacPorts, Nix, Arch, Scoop, Ubuntu, winget, and openSUSE reflects broad use in both Unix and cross-platform developer environments. ### 使用方式 The tool is commonly run over directories of JPEGs to reduce file size, strip or preserve metadata, convert progressive mode, or cap quality. Because it can preserve modification times and permissions and can emit CSV progress, it fits automation as well as one-off cleanup. ### 为什么软件包爱好者会关心 jpegoptim is notable because it turns a libjpeg-compatible encoder into a packaging-era workhorse: tiny CLI surface, old-school C portability, and enough knobs for web-performance pipelines. It also shows the practical boundary between lossless JPEG optimization and deliberate lossy recompression. ### 时间线 - 1996: Copyright period begins in the upstream README. - v1.0: First public release, as listed in the upstream history. - v1.3.0: Added progressive JPEG support and target-size lossy optimization. - 2022-09-15: v1.5.0 added `--workers` for parallel processing. - 2025-09-15: v1.5.6 added `--retry`, `--save-extra`, `--auto-mode`, initial unit tests, and OSSFuzz integration. ### Related projects - Related projects include IJG libjpeg, libjpeg-turbo, mozjpeg, jpeginfo, imageoptim-style GUI tools, and web image build pipelines. ### 来源 - - - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## 其他软件包管理器记录 - Debian apt - jpegoptim - 1.4.7-1: normalized package name match | Debian stable package indexes: jpegoptim from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | utility to optimize jpeg files | http://www.kokkonen.net/tjko/projects.html - Nix - jpegoptim: normalized package name match | nixpkgs package indexes: pkgs/by-name/jp/jpegoptim/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - jpegoptim - 1.4.7-1: normalized package name match | Ubuntu 24.04 LTS package indexes: jpegoptim from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | utility to optimize jpeg files | http://www.kokkonen.net/tjko/projects.html - apk - jpegoptim - 1.5.6-r1: normalized package name match | Alpine Linux edge package indexes: jpegoptim from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | JPEG optimization utility | https://github.com/tjko/jpegoptim - apk - jpegoptim-doc - 1.5.6-r1: normalized package name match | Alpine Linux edge package indexes: jpegoptim-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | JPEG optimization utility (documentation) | https://github.com/tjko/jpegoptim - dnf - jpegoptim - 1.5.6-3.fc45: normalized package name match | Fedora Rawhide package metadata: jpegoptim from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Utility to optimize JPEG files | http://www.kokkonen.net/tjko/projects.html - pacman - jpegoptim - 1.5.6-1: normalized package name match | Arch Linux sync databases: jpegoptim from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Jpeg optimisation utility | https://github.com/tjko/jpegoptim - zypper - jpegoptim - 1.5.6-1.5: normalized package name match | openSUSE Tumbleweed package metadata: jpegoptim from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Utility for Optimizing JPEG Files | https://www.kokkonen.net/tjko/projects.html - MacPorts - jpegoptim: normalized package name match | MacPorts ports tree: graphics/jpegoptim/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 - Scoop - main/jpegoptim: normalized package name match | Scoop official bucket manifest trees: bucket/jpegoptim.json from https://api.github.com/repos/ScoopInstaller/Main/git/trees/master?recursive=1 - winget - TimoKokkonen.Jpegoptim: normalized package name match | Windows Package Manager source index: TimoKokkonen.Jpegoptim from https://cdn.winget.microsoft.com/cache/source.msix ## Combined YAML source View the package source record on GitHub.
