About this converter

Convert JPG photos to WebP locally for smaller, modern web images.

What happens to your file

For supported tools the file is read with the browser File API and held in memory on your device. It is validated, processed by the Image codecs engine in a Web Worker, and the result is handed back as a download. At no point is the file sent to a server.

What to expect from the output

The tool writes WEBP. Formats differ in what they can represent, so expect transparency, colour depth and metadata to be handled differently depending on the format you choose.

How to use this converter

Four steps, none of which involve an account.

  1. 1 Choose your file

    Drop a jpg, jpeg file onto the drop area or browse for it.

  2. 2 Check the output

    The output format is preselected as WEBP. Change it if the tool supports other targets.

  3. 3 Convert

    Everything happens on your device, so speed depends on your machine rather than a queue.

  4. 4 Download

    Save the result, then reset the tool to clear it from memory and start again.

Frequently asked questions

Answers specific to JPG to WebP.

Is this tool free?

Yes. JPG to WebP is free to use and needs no account, no sign-up and no email address.

Where is my file processed?

This tool is being built for local processing, so the file is handled by your own browser. Until that engine is connected the page shows an explicit notice instead of pretending the conversion succeeded.

Which files can I use as input?

Accepted formats are JPG, JPEG. The converter writes WEBP.

Which image conversions run locally?

PNG, JPG and WebP work in modern browsers. Other formats depend on the codecs available in your browser; when a format cannot be decoded, the converter reports that instead of returning a broken file.

Will converting my image reduce its quality?

Lossless formats such as PNG keep every pixel. Lossy formats such as JPG and WebP let you trade a small amount of quality for a much smaller file, and the tool will make that setting explicit.
