Frequently Asked Questions
Common questions about WebP conversion and privacy.
How does this image compressor reduce file size?
The compressor decodes your image in the browser and re-encodes it as WebP using your selected quality setting. WebP compression is usually smaller than JPG or PNG for web use while preserving good visual quality.
Can I compress images without losing quality?
Any lossy compression can remove some image data, but high WebP quality settings usually look visually close to the original. Start around 80–85 quality and increase it if you notice artifacts.
What quality setting should I use?
For most web use, a quality setting of 75–85 provides an excellent balance between file size and visual quality. Lower values reduce file size further; higher values preserve more detail.
Are my images uploaded to a server?
No. All conversions happen entirely in your browser using the Canvas API. Your images never leave your device, making this tool fully private and secure.
Is there a file size limit?
There is no server-side limit because files are processed locally. Very large images may be limited by your device memory and browser capabilities.
How does WebP improve SEO?
Smaller images load faster, which improves Core Web Vitals metrics like Largest Contentful Paint (LCP). Google uses page speed as a ranking factor, so optimized images can help your SEO.
