Image compression reduces file size by removing redundant data. Lossy compression (JPEG, WebP) achieves smaller sizes by discarding some image information, while lossless compression (PNG) preserves all original data.
According to HTTP Archive, images account for approximately 50% of total page weight on average websites. Properly compressed images can significantly improve page load times, user experience, and SEO rankings.

WebP Best For

How does image compression work?
This tool uses the browser's Canvas API to recompress your image at the specified quality level. Lower quality means smaller file size but may reduce image clarity.
What image formats are supported?
You can upload JPEG, PNG, WebP, GIF, and BMP images. The compressed output can be saved as JPEG, PNG, or WebP format.
Will compression affect image quality?
JPEG and WebP use lossy compression, so some quality loss may occur depending on your settings. PNG uses lossless compression. Use the quality slider to balance size vs. quality.
How do I resize an image?
Enable the resize option and choose either percentage scaling or enter exact width/height in pixels. The aspect ratio can be locked or unlocked.
Is my image data secure?
Yes! All compression happens entirely in your browser using the Canvas API. Your images are never uploaded to any server.
What is WebP format?
WebP is a modern image format developed by Google that provides superior compression compared to JPEG and PNG, while maintaining similar or better image quality.
