What's New
Changes to the tools and the guides, newest first. This gets written when something happens — there's no publishing schedule to fill, and JPEG XL produces about four genuine news items a year.

15 October 2026 — Chrome and Firefox switch JPEG XL on, and thirteen new articles
Two big changes in nine days. Chrome 155 (6 October) and Firefox 158 (13 October) now display JPEG XL by default, after years of the format living behind flags. Microsoft Edge 155 is the exception: it still can't show a .jxl. The guides that said otherwise have been corrected, starting with the Chrome guide, and there's a new live test that tells you what your own browser does.
The blog now has one article per question rather than one page trying to cover everything: opening a .jxl on Windows, Mac, iPhone and Android; JPEG XL in Photoshop, Lightroom and GIMP; Firefox; the command-line tools; and comparisons with JPEG, PNG and HEIC based on our own measurements, with the method written down. All of them in English and Spanish.
Less visible: the site moved from Cloudflare Pages to its own server in Germany. Some Spanish internet providers block Cloudflare addresses during football matches, which made the site unreachable from Spain on match days. The privacy policy has been updated to describe the new server and its log.
A fix that should have been there from the start: the JPG to JXL page promises a lossless re-pack, but the “Lossless” box came unticked, so unless you ticked it you got a re-compressed copy instead. It now comes ticked on that page, and the result can be turned back into your original JPEG byte for byte.
29 August 2026 — Five new guides, and the site becomes readable
Five guides published: what a .jpg-large file is (the one Twitter/X leaves you with), what HEIC is, HEIC vs JPG, opening HEIC on Windows without paying for a codec, and whether JPEG XL is lossless.
Alongside them, the guides now behave like a proper publication: every article shows its publication date and author, there's a Spanish index at /es/guias/, and both languages have an RSS feed. The file picker also accepts .jpg-large directly now, so that guide ends at the tool instead of at a dead end.
28 August 2026 — About and Contact
The site had no page saying who runs it or how to get in touch, which is a fair thing to hold against a website. Both now exist, in all five languages, and the viewer pages were rewritten with actual content instead of three sentences.
3 August 2026 — The guides section
Five English guides and an index, covering what a .jxl file is, JPEG XL against AVIF, which software supports the format, archiving without quality loss, and why iPhone photos won't open on Windows.
29 July 2026 — Rewritten for search
Titles and descriptions rewritten across the site, the first three guides published in all five languages, and internal linking added so the pages actually point at each other. Search impressions roughly doubled over the following month.
14 July 2026 — Batch downloads
Converting several files at once now offers a single ZIP, with a manifest listing the original and final size of each image so you can check what you gained before deleting anything.
25 June 2026 — JXL Convert opens
The converter and viewer go live in English, Spanish, German, French and Russian. Everything runs in the browser through libjxl compiled to WebAssembly — including true lossless JPEG re-packing, which needed a custom build because the off-the-shelf ones crashed on anything past about 12 megapixels.
