Convert JPEG XL to PDF
Need to share your JPEG XL images somewhere that only accepts PDF — email, a document pipeline, a print service, or a viewer that can't open .jxl yet? This tool puts each .jxl image onto its own PDF page, sized exactly to the image so nothing is cropped or stretched. Convert whole batches at once, and the page order follows your selection order. Under the hood your browser decodes each .jxl with a WebAssembly JPEG XL decoder, keeps the pixels lossless as PNG, and assembles the document with a local PDF engine — so your images never leave your device. No uploads, no watermarks, no usage limits, and it works offline once the codecs load. Because the conversion is lossless (pixels are preserved exactly), a PDF built here can be larger than one made from JPG, which is the honest trade-off for keeping fidelity. If file size matters more, convert your .jxl to JPG first and put the JPGs into PDF.

Frequently asked questions
Are my .jxl files uploaded to a server?
No. Decoding and PDF assembly happen inside your browser from local files. That makes it suitable for sensitive scans and photos that shouldn't be sent anywhere.
Why is my PDF bigger than expected?
PDF has no native JPEG XL support, so each .jxl is decoded and embedded as lossless PNG to preserve every pixel. For smaller PDFs, convert your .jxl to JPG first with our JXL to JPG tool, then put the JPGs into PDF.
How is the page size determined?
Each page exactly matches its image dimensions, so no cropping or letterboxing occurs. For uniform pages, convert images of the same size.
Can I control the image order?
Pages follow the order of selection. To change the order, clear the list and pick the files again in sequence.
Can I merge this PDF with other PDFs?
Yes — download the converted PDF, then use our Merge PDF tool to combine it with other documents.
How many images can I convert at once?
Up to 200 per batch. Every image is decoded and losslessly embedded, so very large batches can exhaust browser memory — split them into a few smaller PDFs and combine the results with our Merge PDF tool.
