Convert HEIF to WEBP

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.

WebP is a modern image format developed by Google that offers superior compression for web graphics. It supports both lossy and lossless compression, providing smaller file sizes compared to JPEG and PNG while maintaining high image quality. WebP images feature transparency like PNG files and can display animations like GIF files. This format helps websites load faster and reduces bandwidth usage.

WebP output is useful when smaller files matter, such as images for websites, and the receiving software supports the format. WebP can be smaller than JPG at similar visual quality, though results depend on the image and quality setting. If a client, printer, or older app may not open WebP, JPG is the safer choice.

.WebP images fully support transparency through an alpha channel, similar to PNG files. The format allows both binary (fully transparent or fully opaque) and variable transparency levels (partial opacity). When using lossy compression, WebP maintains high-quality transparency while achieving smaller file sizes compared to PNG. The lossless WebP variant preserves transparency without any quality degradation, making it ideal for logos, icons, and graphics requiring clear backgrounds.

Some quality loss is possible. Framebird decodes your HEIF image and encodes a new WebP file, and WebP output from this tool can lose fine detail. The default quality setting is 90, which suits most everyday uses. Even quality 100 does not guarantee an identical image. Metadata from the source is not copied, so keep your original HEIF file as a backup.
