How to convert to WEBP
WebP is Google's modern image format that compresses images more efficiently than JPEG or PNG while supporting transparency and animation. At equivalent visual quality, lossy WebP files are typically 25 to 35 percent smaller than JPEG and lossless WebP is 25 to 35 percent smaller than PNG. All major browsers have supported WebP since 2020, making it practical for production web use. Converting images to WebP is one of the highest-impact image optimization steps for web performance.
This converter accepts any image file you upload and encodes it as WebP directly in your browser using WebAssembly. The image never leaves your device. Choose between lossy and lossless modes, adjust the quality setting, and download the result. Transparency from PNG source files is preserved in both modes.
Upload the source image
Drop any image file: PNG, JPEG, AVIF, GIF, BMP, TIFF, or HEIC are all accepted. The format is detected automatically.
Choose mode and quality
Lossy WebP at quality 80 to 85 is the best choice for photographs: significant size reduction with minimal visible quality loss. Lossless WebP is better for logos, illustrations, and images requiring exact pixel preservation.
Convert in browser
The WebAssembly encoder processes the image locally. For large photographs, encoding at high quality may take a few seconds. No server or internet connection is needed.
Download and deploy
Save the WebP file. Update your HTML image tags or CSS to reference the new file. For compatibility, use the picture element with a WebP source and a JPEG or PNG fallback.
Frequently asked questions
How much smaller will my image be as WebP?
Typically 25 to 35 percent smaller than JPEG at similar visual quality for lossy mode, and 25 to 35 percent smaller than PNG for lossless mode. Results vary by image content; photos with complex textures compress better than flat-color graphics.
Does WebP support animation?
Yes. Animated WebP is supported in all major browsers and produces smaller files than animated GIF. This converter produces static WebP; for animated WebP, you need a tool that accepts a frame sequence.
Is my image uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly. Nothing is sent to any server.
Do I need a JPEG or PNG fallback for older browsers?
WebP support exceeded 96 percent of global browser usage by 2023. IE11 does not support WebP. If you need to support IE11, keep a JPEG fallback using a picture element. For all other browsers, WebP alone is sufficient.
Should I use lossless or lossy WebP for screenshots?
Lossless WebP is the correct choice for screenshots, UI documentation, and images with sharp edges and text. Lossy WebP applies block compression that blurs text and introduces ringing artifacts at edge boundaries, which is obvious in screenshots.
