Frequently Asked Questions
What is a WebP file?
WebP is a modern image format developed by Google that provides superior compression for images on the web. WebP files are typically 25–35% smaller than comparable JPEG or PNG files at the same visual quality, making them ideal for websites and web applications.
How do I compress WebP images?
Upload your WebP files to SlimPix, adjust the quality slider to your preferred level, and click Compress. SlimPix compresses WebP images directly in your browser with no upload to any server.
Can I convert WebP to JPEG or PNG while compressing?
Yes. SlimPix lets you change the output format during compression. Select JPEG or PNG from the format options to compress and convert at the same time.
Is WebP better than JPEG?
WebP generally produces smaller files than JPEG at equivalent quality. It also supports transparency (like PNG) and animation (like GIF). However, JPEG has broader compatibility with older software. For web use, WebP is usually the better choice.
