Complete Guide to Converting Images to WebP
This free image compressor helps you make image files smaller for websites, email, WordPress, ecommerce, and social platforms. It converts common image formats to optimized WebP directly in your browser, giving you smaller downloads without sending files to a remote server.
You can compress one image or a batch of files at once.
Supported Image Formats
| Input | Best for |
|---|---|
| JPG / JPEG | Photos, product images, blog graphics |
| PNG | Screenshots, UI graphics, transparent assets |
| GIF | Static GIF frame compression |
| BMP | Large bitmap files |
| TIFF / TIF | Scans and high-resolution exports |
| WebP | Recompressing existing WebP images |
All compressed downloads are generated as WebP files because WebP is usually smaller for web delivery.

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.
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.
Can I convert multiple images at once?
Yes. Drag and drop multiple files or select them using the file picker. Each file is converted individually and you can download them one by one or use Download All.
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.
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.
