// about this tool
WebP is a modern image format developed by Google that achieves significantly smaller file sizes than JPEG and PNG at comparable visual quality. This tool converts images to WebP entirely in your browser using the Canvas API — no files are sent to any server. A quality slider controls the lossy compression level, and a side-by-side canvas shows the original versus the converted result.
// when to use
- Optimise hero images and product photos before uploading to a website
- Compare WebP quality levels to find the best size-to-quality tradeoff
- Convert screenshots to WebP for use in documentation or blog posts
- Batch-check how much file size WebP would save for a set of images
// faq
Does the original file leave my device?
No. The conversion is done entirely in your browser using the HTML Canvas API. The image is read locally, drawn to a canvas, and exported as a WebP blob — no network request is made at any point.
Which source formats are supported?
Any format your browser can decode: JPEG, PNG, GIF (first frame), BMP, AVIF, and WebP itself. HEIC/HEIF is not universally supported — it depends on the browser and OS. If the image doesn't load, try converting it to PNG first.
