About this tool

WebP is a widely supported image format that often produces smaller files than JPEG or PNG at similar visual quality — ideal for faster websites and sharing. This tool runs entirely in your browser: your file never leaves your device.

Upload a JPG, PNG, or WebP image, preview the original and the WebP output, compare file sizes, and download the result. All major browsers now support WebP natively, making it the best choice for web-optimised images.

Quick answers about this free online tool.

Upload a JPG, PNG, or WebP file. The image is drawn to an HTML canvas in your browser and exported as WebP — nothing is uploaded to a server. Then preview the result and download.

Output uses lossy compression at a fixed quality setting (0.8) for a balance of size and visual quality. Results vary by image content.

No. Conversion runs entirely in your browser using the Canvas API. Files are not sent to us or stored.

JPEG, PNG, and WebP uploads are supported, up to 25 MB. Very large dimensions are scaled down so the canvas stays within safe browser limits.

Some older browsers cannot encode WebP from a canvas. Try Chrome, Edge, or Firefox.
