How to convert JXL to JPG
- Drop the JXL.
- Pick a quality.
- Press Convert and download.
What happens to your file
libjxl decodes the JPEG XL on Fylane’s servers into a lossless PNG, and the ordinary pipeline encodes the JPG at your quality. A JXL made losslessly from a JPG comes back as the same picture; a JXL from a camera or HDR source is tone-mapped to what a JPG can hold.
Questions
Why does nothing open my JXL?
JPEG XL is the newest image format; Safari and a few apps read it, most do not. Convert what you need to share.
Do it once, not on every form
A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
