How to convert GIF to PNG offline

Choose local GIF image files, choose "PNG" as target image format, then click the "CONVERT OFFLINE" button to start offline conversions in bulk. File size can be up to 2GB.

This offline converter will try to use canvas in web browser to convert images first. The image format depends on whether your current web browser supports. For example: the latest Chrome browser supports AVIF images while some old versions don't. Then the offline converter will try to use JavaScript to convert images if your current web browser doesn't support the image format.

Introduction	The Graphics Interchange Format (better known by its acronym GIF) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.	Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet. PNG itself does not support animation at all. MNG is an extension to PNG that does; it was designed by members of the PNG Group.
