Convert HEIF to PNG

HEIF (High Efficiency Image Format) is a modern image file format that offers superior compression compared to JPEG while maintaining higher image quality. Developed by MPEG, it can store both still images and image sequences. HEIF files typically use the .heif extension and are particularly popular on Apple devices running iOS 11 or later. The format supports features like transparency, 16-bit color, and HDR imaging.

PNG (Portable Network Graphics) files are lossless image files that support transparency and millions of colors. Created in 1996 as an alternative to GIF, PNGs excel at displaying sharp graphics, logos, and text-heavy images. They maintain crisp edges and vibrant colors without quality loss during compression. While larger in file size than JPEGs, PNGs are ideal for web graphics requiring transparency or precise detail preservation.

PNG output is useful when you need transparency or want to keep the decoded pixels without further compression loss, such as for graphics, screenshots, or files you will edit again. The tradeoff is size: photographs saved as PNG are often much larger than JPG. For sharing photos where size matters, JPG may be the more practical choice.

PNG files fully support transparency through an alpha channel, allowing both fully transparent and semi-transparent pixels. This makes PNG ideal for logos, icons, and images that need to blend seamlessly with different backgrounds. Unlike JPEG, PNG's lossless compression preserves sharp edges and transparency without quality degradation, though file sizes may be larger. The format supports both binary transparency (fully visible or invisible pixels) and variable transparency levels (partial opacity).

PNG encoding is lossless, so Framebird keeps the decoded pixels exactly as they come out of your HEIF file. It cannot restore detail that was already lost when the HEIF was first compressed. Framebird decodes the image and writes a new PNG file, which may be larger than the original. Source metadata is not copied, so keep your original HEIF file as well.
