It is strongly associated with the late-1990s move from GIF toward PNG on the open web. ### Project history The project predates its GitLab hosting and has a long changelog preserved by Eric S. Raymond's project page. The NEWS file shows releases in 1999 leading up to version 2.0.0, which was marked ready for Burn All GIFs Day, a campaign-era milestone in PNG advocacy. Development continued through portability, packaging, and correctness work: DocBook documentation in 2002, RPM and Freshmeat packaging updates in 2003, libpng and security fixes in the 2000s and 2010s, a simpler makefile after Autotools removal in 2015, a Go port in 2019, and Go module packaging in 2023. ### Adoption history gif2png's adoption was rooted in a specific historical problem: GIF was ubiquitous but politically and technically contentious, while PNG offered a patent-free replacement for many web graphics. The utility gave web maintainers a batchable path to convert image assets and update references. The package's continued presence in Homebrew, Fedora, Arch, and other packaging indexes reflects its role as a small, stable conversion tool rather than a large image suite. Users who need this exact conversion can install a purpose-built command instead of pulling in a broad graphics application. ### How it is used Practitioners use `gif2png` for file-level GIF to PNG conversion and `web2png` when converting a directory tree of web pages and image references. The README describes POSIX and Go build requirements, a regression test suite, and the `make check` workflow. Typical use is archival cleanup, static-site maintenance, packaging tests around image conversion, or migration of old GIF-heavy web assets to PNG. ### Why package nerds care gif2png is package-nerd significant because it is old, focused, and still easy to package. Its changelog records decades of small portability and correctness fixes, including security hardening and a language-port transition from C-era tooling to Go while keeping the command-line identity intact. ### Timeline - 1999: Version 2.0.0 was prepared for Burn All GIFs Day. - 2002: Documentation masters moved to DocBook. - 2003: RPM and Freshmeat packaging updates landed in the 2.5 series. - 2012: A filename buffer overflow fix for CVE-2009-5018 was released. - 2015: Autotools was removed in favor of a simple makefile. - 2019: The code was ported to Go. - 2023: The build was converted to a Go module. - 2026: Version 3.0.4 updated web2png for Python 3. ### Related projects - gif2png is related to PNG, GIF, libpng, web2png, Burn All GIFs Day, and small Unix-style image conversion utilities. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** gif2png - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - dnf - gif2png - 3.0.4-1.fc45: normalized package name match | Fedora Rawhide package metadata: gif2png from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | A GIF to PNG converter | http://www.catb.org/~esr/gif2png/ - pacman - gif2png - 3.0.3-2: normalized package name match | Arch Linux sync databases: gif2png from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | A GIF to PNG image format converter | http://www.catb.org/~esr/gif2png/ ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [Web development packages](https://www.automicvault.com/pkg/web-dev-tools/) - Matched web development metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [xmlto](https://www.automicvault.com/pkg/brew/xmlto/) - Build dependency declared by Homebrew. - [makeicns](https://www.automicvault.com/pkg/brew/makeicns/) - Shares av.db curated category or tags: cli, conversion, image, image-conversion, media. - [gifcap](https://www.automicvault.com/pkg/brew/gifcap/) - Shares av.db curated category or tags: cli, gif, image, media. - [gifify](https://www.automicvault.com/pkg/brew/gifify/) - Shares av.db curated category or tags: cli, conversion, gif, media. - [gifsicle](https://www.automicvault.com/pkg/brew/gifsicle/) - Shares av.db curated category or tags: cli, gif, image, media. - [gifski](https://www.automicvault.com/pkg/brew/gifski/) - Shares av.db curated category or tags: cli, gif, image, media. - [gimme-aws-creds](https://www.automicvault.com/pkg/brew/gimme-aws-creds/) - Shares av.db curated category or tags: cli, gif, image, media. - [pdf2image](https://www.automicvault.com/pkg/brew/pdf2image/) - Shares av.db curated category or tags: cli, conversion, image-conversion, media. - [swiftdraw](https://www.automicvault.com/pkg/brew/swiftdraw/) - Shares av.db curated category or tags: cli, conversion, media, png. - [apng2gif](https://www.automicvault.com/pkg/brew/apng2gif/) - Both packages work with overlapping file formats or content types.
