Frequently Asked Questions
What is WebP format?
WebP is a modern image format developed by Google that provides superior compression compared to JPEG and PNG. WebP images are typically 25-35% smaller while maintaining the same visual quality, making them ideal for web use.
Why should I convert images to WebP?
WebP offers significantly better compression than traditional formats. Smaller images mean faster page loads, lower bandwidth costs, better SEO rankings, and improved Core Web Vitals scores. Most modern browsers support WebP.
Which browsers support WebP?
WebP is supported by all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. Safari added WebP support in 2020 (macOS Big Sur / iOS 14), so coverage is now nearly universal.
What does the quality slider do?
The quality setting (10-100%) controls the compression level. Lower values create smaller files but may show compression artifacts. For most uses, 75-85% offers the best balance. Use 95-100% for archival or when quality is critical.
Is my image uploaded to a server?
No! All conversion happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device. We cannot see your images, and no data is collected or stored.
What image formats can I convert to WebP?
This tool accepts PNG, JPEG (JPG), GIF, BMP, and even existing WebP images as input. You can re-compress WebP images at different quality levels.
Does WebP support transparency?
Yes! WebP supports both lossy and lossless compression, as well as transparency (alpha channel). When you convert a PNG with transparency to WebP, the transparency is preserved.
How much smaller will my images be?
Results vary by image content, but typical savings are 25-35% compared to JPEG and 26% compared to PNG for lossy compression. Some images see 50%+ reduction. The tool shows exact before/after file sizes.
