Convert JPG to WebP in your browser

WebP files are often smaller than JPG files of similar quality, which makes pages load faster. This tool turns JPG images into WebP files on your device. Nothing is uploaded.

It uses your browser's own WebP encoder. Safari cannot create WebP files, so use Chrome, Edge or Firefox.

JPG to WebP

Your images are converted on this device and never uploaded.

JPG → WebP

Higher numbers give better quality and larger files. 80 suits most photos.

Safari cannot create WebP files. Use Chrome, Edge or Firefox.

Metadata such as the location, camera and date is not copied into the new file. Colors are converted to sRGB.

    How it works

    1. Set the WebP quality. 80 suits most photos.

    2. Choose your JPG files, or drop them anywhere on the page. Conversion starts right away.

    3. Check the size before and after on each row, then download each WebP file, or all of them as one ZIP file.

    Your browser decodes each JPG in a background worker and encodes it as WebP with its built-in encoder. The image is not sent anywhere.

    Questions

    What it does and what it does not

    Privacy, metadata, file limits and browser support.

    Are my images uploaded?

    No. The page and its encoders load from quireapps.com, and after that each image is read, converted and saved inside your browser tab. There is no analytics or tracking on this page. You can check this in your browser's developer tools, on the Network tab: converting an image makes no requests.

    Why does it not work in Safari?

    Safari can open WebP images but cannot create them: when a page asks Safari for a WebP file, it returns a PNG instead. This page checks for that and shows a warning in Safari. Use Chrome, Edge or Firefox, or, if you only need a smaller file, use the image compressor to make a JPG.

    How much smaller will the WebP be?

    It depends on the image and on how hard the JPG was compressed. Each row shows both sizes. A JPG that was already compressed hard can come out larger as WebP at a high quality setting; in that case try a lower setting or keep the JPG.

    Does it lose quality?

    A little. The JPG is decoded and compressed again with WebP's lossy encoder, so some detail is lost each time. At the default quality of 80 the difference is hard to see on most photos. Higher settings lose less and give larger files.

    What happens to the metadata?

    It is not copied. The new file has no EXIF location, camera details or date taken. The EXIF orientation is applied to the pixels first, so the image keeps the way it was displayed. Colors are converted to sRGB and no color profile is written. To remove metadata without converting, use the EXIF remover.

    Are there limits?

    Each file can be up to 50 MB and 100 megapixels, and the list holds up to 100 files at a time. Safari on iPhone and iPad limits images to about 16.7 megapixels for this kind of processing, so larger images can fail there. Files are converted one at a time.

    Which browsers does it work in?

    It is tested in Chrome. Edge and Firefox should also work, but have had less testing here. Safari cannot create WebP files, and the page shows a warning if your browser cannot.

    Is it free?

    Yes. There is no account, no sign-up, no watermark and no daily limit.
