Convert Images to WebP Online

WebP is the modern image format for the web: it looks the same as JPG or PNG but is often dramatically smaller — frequently just a few kilobytes. Upload up to 10 JPG, PNG, GIF or BMP images and download the converted WebP files in a single ZIP.

How It Works

Choose one or more images, set the quality level, then press Run. Each file is re-encoded to WebP, and the result reports the total space saved. When several images are uploaded they are bundled into one ZIP archive, with each file keeping its original name.

Why Use WebP?

WebP typically produces files 25–80% smaller than JPEG or PNG at comparable quality, which speeds up page loads and reduces bandwidth. All modern browsers support it, making it a safe default for websites and apps.

Supported Input Formats

JPG, PNG, GIF and BMP are accepted. Transparency from PNG and GIF is preserved where WebP supports it. Images that are already WebP are rejected with a clear message, since converting them again would only add noise.

Privacy & Security

Files are processed on our server only to create your result and are deleted afterwards. Download links expire automatically and nothing is shared or sold.

Free & Unlimited

No sign-up, no watermarks and no daily limits. Convert as many images as you need.

Frequently asked questions

How many images can I convert at once?

Up to 10 images per run, as long as their combined size stays within the upload limit. They come back as one ZIP file.

Does WebP support transparency?

Yes. WebP supports an alpha channel, so transparent PNG and GIF images keep their transparency after conversion.

Why was my WebP image rejected?

Files that are already in WebP format are refused, because re-encoding them would not improve quality or size.
