What is JPG?

JPG (or JPEG) is the most widely used photo format. Its lossy compression keeps files small and it opens everywhere, but it has no transparency.

What is JPEG XL?

JPEG XL is the successor to JPG: smaller files at the same quality, transparency, HDR and lossless mode. Safari opens it, but most other browsers and programs still don’t.

Questions

Does converting JPG to JPEG XL lose quality?
JPEG XL uses compression to keep files small. At the default quality (85) the difference is practically invisible, and you can raise it under Advanced Options.
Do you store my files?
No. Your files are never uploaded, so there is nothing for us to store. They only exist in your browser’s memory while the page is open and are deleted when you remove them, clear the list or close the tab. We only count anonymous usage, like how many conversions happen, never file names or contents.
Is it safe?
Yes. Your files are converted on your own device and are never uploaded to any server.
Is it free?
Yes. It’s free, with no sign-up, no watermarks and no ads.
Is there a limit?
We don’t set any limit on the number or size of files. Since everything happens on your device, its memory is the real limit: on a computer, 100-megapixel photos, 300-page PDFs and long videos convert without trouble. Phones have less room. Video and audio use your browser’s codecs, so Chrome and Edge support the most formats. If something doesn’t work, we’ll tell you.
Does it work on my phone?
Yes, in any modern browser on iPhone, Android or desktop.
