How WebP Conversion Can Improve Page Speed & SEO
Core Web Vitals’ LCP measures how quickly the largest visible element appears on a page.
Converting images to WebP can significantly reduce file sizes compared to JPG and PNG, helping improve page speed and user experience.
On image-heavy websites, switching to WebP alone can noticeably improve loading performance.
WebP is widely used by ecommerce stores, blogs, news sites, and content-rich platforms.
What Happens When You Convert Animated GIFs to WebP
WebP supports animated images just like GIF and also preserves transparency (alpha channel). In many cases, animated WebP files are much smaller than GIFs while maintaining similar visual quality.
If you need to convert a WebP file back to GIF, simply choose the “Convert WebP to GIF” option.
Keep in mind that GIF files are limited to 256 colors, so converting from WebP to GIF may result in reduced color accuracy or visible quality loss.
How Online WebP Conversion Works Without Installing Software
Some desktop WebP converter applications require additional setup depending on the operating system or software version.
Vivoldi handles image conversion directly on the server, so there’s nothing to install or configure.
It works consistently across Windows, macOS, Linux, and other platforms. Once the conversion is finished, your files are immediately ready to download.
How to Convert WebP Files When They Won’t Open Properly
WebP is supported by most modern browsers, but older image editors or certain printing environments may not fully support the format.
By selecting “Convert WebP to Another Format”, you can export WebP images as PNG, JPG, HEIC, AVIF, TIFF, BMP, and other formats.
Simply choose the format that best matches your needs. If additional editing is required, you can continue working with the file in the Image Editor.

To save HEIC or AVIF as PNG or JPG, first convert it to WebP, then choose the desired output in WebP to another format mode. Colors, transparency and file size can vary; check the result.

WebP is an image format developed by Google that supports still images, animation and transparency.
File size changes depend on the source format, dimensions, quality and existing compression. Savings and visual quality are not identical for every image, so check the converted result before use.
Lower quality can alter text edges and fine image details. Compare higher-quality results for screenshots and images containing text.
Resizing reduces pixel count; increasing quality does not restore removed detail. The selected originals remain available, so you can adjust the settings and convert again.
Still-image outputs such as PNG and JPG contain only the first frame. Choose WebP to GIF to preserve animation. GIF conversion requires Personal or higher.
GIF has limits on colors and transparency, so results can differ from the source. Check playback and colors in the converted file.
