'''动态可移植网络图形'''（{{langx|en|Animated Portable Network Graphics}}，缩写{{lang|en|'''APNG'''}}）是一种继承自[[便携式网络图形]]（PNG）的文件格式，它允许像[[GIF]]格式一样播放动态图片，并且拥有GIF不支持的24位图像和8位透明性。它还保留了与非动画PNG文件的向后兼容性。

APNG文件的第一帧存储为普通PNG流，因此大多数标准PNG解码器都能够显示APNG文件的第一帧。帧速度数据和额外的动画帧存储在额外的数据块中（如原始的PNG规范所规定）。 APNG的竞争者是由PNG团队创建的位图动画的全面格式——[[多重網絡圖形 ]]（MNG）。与其相比，APNG的优势是更小的存储大小以及对旧的PNG完全兼容。

通过对比GIF、APNG和[[WebP]]，可以看出APNG在质量相同的时候有着更小的体积<ref>{{Cite web |title=GIF vs APNG vs WebP |url=http://littlesvr.ca/apng/gif_apng_webp.html |access-date=2019-04-02 |publisher=littlesvr |archive-date=2020-11-01 |archive-url=https://web.archive.org/web/20201101150902/http://littlesvr.ca/apng/gif_apng_webp.html }}</ref>。

== 历史 ==
[[File:APNG Assembler Logo.svg|105px|thumb|right|[[自由软件]]APNG Assembler的Logo，它可以用来制作APNG图片。]]
2004年，APNG由[[Mozilla公司]]的Stuart Parmenter和[[Vladimir Vukićević]]所創立，希望Mozilla社区将其用于[[图形界面]]及[[XUL]]，也期望广泛用于网页，但提案未能通过。

2006年，[[Google Summer of Code]]活动中，加拿大圣力嘉学院的学生为libpng程序库加入APNG支持。

此后开发者继续向Mozilla社区推荐APNG，但一直没有什么进展。

2007年3月23日，[[Mozilla Firefox]] 3.0在开发测试中支持APNG。<ref>{{cite web|url=http://www.mozilla.org/projects/firefox/3.0a3/releasenotes/|title=Gran Paradiso Alpha 3 发布日志|date=2007-03-23|deadurl=yes|archiveurl=https://web.archive.org/web/20100509065420/http://www.mozilla.org/projects/firefox/3.0a3/releasenotes/|archivedate=2010-05-09|accessdate=2007-07-24}}</ref>

2007年4月20日，PNG组织投票以10:8否决APNG进入官方标准。PNG组织决心继续推广[[多重網絡圖形|MNG]]，不过其权力有限，许多常见软件陆续支持了APNG。

2025年6月24日，PNG发布3.0版本标准，正式将APNG纳入官方标准中。<ref>{{Cite web |title=超過20年沒有改版，PNG 3.0支援HDR顯示與原生動畫顯示 |url=https://www.4gamers.com.tw/news/detail/72760/png-3-support-hdr- |website=4Gamers 官方網站 |language=zh-Hant |last=4Gamers |access-date=2025-08-03}}</ref>
