Convert PNG to WEBP

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.

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 lose some detail. Framebird decodes the PNG pixels and encodes a new WebP file, and WebP output can lose detail. The default quality setting is 90. Setting quality to 100 can reduce loss, but it does not guarantee an identical image. Sharp edges, text and flat colors may show changes. Source metadata is not copied. Keep your original PNG in case you need it later.
