Convert AVIF to WEBP

AVIF (AV1 Image File Format) is a modern image format that offers superior compression and quality compared to JPEG, PNG, and WebP. Developed by the Alliance for Open Media, AVIF supports both lossy and lossless compression, HDR, wide color gamut, and transparency. Its efficient encoding reduces file sizes while maintaining excellent image quality, making it ideal for web content and digital media storage.

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.

You can. Framebird decodes the AVIF pixels and encodes a new WebP file. WebP output can lose detail, even at the highest setting. The default quality is 90, and quality 100 does not guarantee an identical image. Source metadata is not copied to the new file. Keep your original AVIF in case you need the full source later.
