# Convert PNG to JXL in your browser.

Web page: https://converter.chabulab.com/png-to-jxl/

This is the Markdown version of https://converter.chabulab.com/png-to-jxl/, 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.

PNG is lossless and keeps transparency, so it is what screenshots, icons and graphics get saved as. 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. This page moves a PNG to a JXL 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.

JXL 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.

Encoding JXL also runs on your device rather than on a server, so a file you would normally hand to a website is written by your own machine.

## Why convert PNG to JXL

- You want to keep the exact pixels of a PNG but store the file in far fewer bytes.

- You are archiving lossless images and want a modern container for them.

### What to expect

- The conversion preserves the image; it does not reduce resolution unless you choose to.

### PNG to JXL questions

#### Is converting PNG to JXL 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 PNG 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 JXL keep transparency?

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

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

Some, and it depends on the picture and the setting. JXL 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.

#### Can I open the JXL file this page gives me?

Not in a browser, not yet. No current browser displays JXL; it is for software that has its own codec. If you need a file anything will open, convert to JPG or PNG instead.

#### Can I convert more than one PNG 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.
