Convert animated PNG images (APNG) online for free
The converter easily converts your APNG animated images to various formats - free and online. No Mozilla Firefox or other Raster Image software needed.
The converter also works in reverse, so you can convert other "Animated Image" formats to APNG without using software like Mozilla Firefox or a similar tool.
The .APNG (Animated Portable Network Graphics) format is an unofficial extension of the standard PNG specification that allows for animated images. Designed by Mozilla Corporation as an alternative to the aging GIF format, .APNG supports 24-bit color depth and 8-bit alpha transparency. You can view these files natively in modern browsers like Mozilla Firefox and Google Chrome, and learn more on its Wikipedia page.
Despite its superior image quality, the .APNG format comes with severe disadvantages. It lacks the advanced inter-frame compression found in modern video codecs, resulting in massive file sizes that slow down website load times and consume heavy bandwidth. Furthermore, compatibility remains an issue; many content management systems, legacy image viewers, and social media platforms do not recognize the animation chunks, causing the file to fail silently and display only the first static frame.
To overcome these performance and compatibility limits, conversion is highly recommended. For fast-loading web animations, convert to WEBP or AVIF. For social media uploads and maximum compression, convert to video formats like MP4 or WEBM. If you need to support legacy systems, convert down to GIF (though you will lose color depth and smooth transparency). Drag and drop your file to analyze and convert it - free, online, and without installing software.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our APNG converter.
