# Convert JXL to WebP in your browser.

This is the Markdown version of https://converter.chabulab.com/jxl-to-webp/, for a reader that would rather not parse the page's HTML. The converter itself is at https://converter.chabulab.com/ and runs on your own device.

JPEG XL is a next-generation format that beats JPG and PNG on size while still offering lossless, but no browser can display it yet. WebP is the modern web format: smaller than JPG at the same quality, with transparency, and every current browser reads it. This page moves a JXL to a WebP in your own browser: the file is read, re-encoded and handed back without being uploaded.

Both formats carry transparency, so a transparent background survives the conversion.

WebP is a lossy format: the encoder discards detail to make the file smaller, and the quality slider on this page is how you choose how much.

No browser can decode JXL, so this page ships its own decoder and runs it in a worker on your device. That is what the first JXL conversion is waiting for.

## Why convert JXL to WebP

- You want a small web image from a JPEG XL file.

- You are converting a stored JXL into something browsers display today.

### What to expect

- The page decodes the JXL itself, then encodes WebP locally.

### JXL to WebP questions

#### Is converting JXL to WebP free?

Yes, and there is nothing to unlock. The conversion runs in your browser, so there is
           no account, nothing to pay and no licence key to enter. Every format and every
           feature on the site is available to everyone.

#### Are my JXL files uploaded anywhere?

No. Your file is decoded and re-encoded inside this tab and never uploaded. The ads on this page are served by Google and do see that you are here, but they never see your file. You can check it yourself: open the network panel and search for a request carrying your picture.

#### Does the WebP keep transparency?

Yes. Both JXL and WebP carry an alpha channel, so a transparent background comes through unchanged.

#### How much quality do I lose converting JXL to WebP?

Some, and it depends on the picture and the setting. WebP is lossy, so it throws away detail the encoder thinks you cannot see. The quality slider is adjustable from 10 to 100 before you convert, and the queue shows you the resulting file size so you can trade one against the other.

#### Do I need to install anything to open a JXL file?

No. No browser can read JXL, so this page ships its own decoder and loads it the first time you convert one. The file never leaves your device to be decoded anywhere.

#### Can I convert more than one JXL file at once?

Yes. Drop a batch onto the page and every file is converted in the
    queue, then downloaded together. The queue also shows the size before and after, so you
    can see what the conversion saved. There is no cap on how many files you convert at once;
    the only real limit is what your device can hold in memory at the same time.
