Transform your HEIC files into PNG format instantly within your browser.
HEIC is Apple's file extension for images encoded under the High Efficiency Image File Format (HEIF) standard, using HEVC (H.265) compression. Apple made it the default photo format on iPhones starting with iOS 11, since it stores images at roughly half the file size of an equivalent-quality JPEG. As a container format, a single HEIC file can also bundle image bursts, depth data, or Live Photo sequences together. The main friction point is compatibility: older software, most Windows PCs, and many web platforms still can't open HEIC natively, which is the main reason people convert it to JPG.
PNG (Portable Network Graphics) is a lossless raster format released in the mid-1990s as a royalty-free successor to GIF, after a licensing dispute over the LZW compression algorithm. It compresses images with the DEFLATE algorithm, the same method used by ZIP archives, so every pixel is preserved exactly with no generation loss on repeated saves. PNG also supports a full 8-bit alpha channel for smooth, partial transparency, unlike GIF's binary on/off transparency. These properties make it the standard choice for screenshots, logos, icons, and any graphic with sharp edges, flat colors, or text that needs to stay perfectly crisp.
