WebM konvertiĝo FAQ

What is a WebM file?

WebM is a modern image format developed by Google that provides superior compression for images on the web. WebP supports both lossy and lossless compression, transparency, and animation. It typically creates files 25-35% smaller than JPEG or PNG with equivalent quality.

How do I convert WebM files?

Upload your image using drag-and-drop or click to browse. Select WebP as output, or choose another format if converting from WebP. Adjust quality settings as needed and click Convert. Your optimized image will be ready for download instantly.

Is the image conversion free?

Yes, our WebP converter is completely free for basic use. Convert images without creating an account. Premium features are available for batch conversion and advanced optimization options.

Which browsers support WebP?

WebP is now supported by all modern browsers including Chrome, Firefox, Edge, Safari (14+), and Opera. Over 95% of web users can view WebP images natively. For older browsers, you can provide JPEG/PNG fallbacks or convert to a more compatible format.

Is WebP better than JPEG?

WebP offers 25-35% better compression than JPEG at equivalent quality, resulting in faster page loads. WebP also supports transparency (unlike JPEG) and animation. For web use, WebP is generally the better choice. JPEG remains useful for maximum compatibility and print workflows.

Does WebP support transparent backgrounds?

Yes! WebP fully supports alpha transparency, similar to PNG. This makes WebP ideal for logos, icons, and graphics with transparent backgrounds. WebP transparent images are typically much smaller than equivalent PNG files while maintaining quality.

Can WebP replace animated GIFs?

Absolutely! Animated WebP files are dramatically smaller than GIFs (often 50-90% smaller) while supporting more colors and smoother animation. Converting your GIFs to animated WebP will significantly improve page load times and reduce bandwidth usage.

Should I use lossy or lossless WebP?

Use lossy WebP for photographs and complex images where small quality losses are imperceptible. Use lossless WebP for graphics, screenshots, or images with text where you need pixel-perfect quality. Lossy offers smaller files, lossless preserves every detail.

Can I use WebP with WordPress or other CMS?

Yes, WordPress 5.8+ natively supports WebP uploads. Most modern CMS platforms support WebP, and plugins are available to automatically convert and serve WebP images with fallbacks for older browsers. Converting to WebP can significantly improve your site's Core Web Vitals scores.

How do I convert WebP to JPEG or PNG?

Upload your WebP file to our converter and select JPEG, PNG, or any other supported format as output. This is useful when you need to edit images in software that doesn't support WebP, or when sharing with users who need more compatible formats.
