Convert Images in 4 Simple Steps
Quickly transform your images with our streamlined conversion process. Every file is processed through a scalable background queue with real-time status updates — so you can convert hundreds of images at once and watch each one move from In queue to Processing to Ready. No software installation required.
Upload Image Files
Click 'Choose Files' or drag & drop your images into the upload area. Supports multiple files at once.
Select Format & Settings
Choose your target format (WebP, PNG, JPG, etc.) and adjust quality, size, and other conversion options.
Queued & Converted
Click 'Convert All' and each image is queued and processed in the background. Track live status for every file — In queue, Processing, then Finalizing — updated in real time.
Download
As soon as a file is Ready, download it individually or grab everything as a ZIP. Queued processing keeps large batches going even with hundreds of images.
How the Image Converter Works
Drop your images, pick a target format, and convert. Every file is queued and processed in the background with real-time status — In queue, Processing, then Ready — so you can convert hundreds of images at once without the page freezing.
From PNG to JXL: The Next Generation of Image Compression
PNG is the universal web standard, but it's fundamentally optimized for lossless compression — which means file sizes balloon when storing photographs. JPEG XL (JXL), released in 2021 by the Joint Photographic Experts Group, was built as JPEG's modern successor to solve this exact problem: better compression than JPEG at equivalent quality, plus support for lossless and lossy compression in the same standard, along with HDR, wide color gamut, transparency, and even animation. Converting PNG to JXL gives you the same visual content in a far smaller file, with modern browser support and forward-looking format architecture.
Why Convert PNG to JXL?
If you're optimizing for modern web performance and your audience uses current browsers, JXL represents the future of image compression. It compresses photographs and graphics more efficiently than both JPEG and PNG, making it ideal for bandwidth-conscious projects, mobile-first sites, and scenarios where performance metrics directly impact user retention and SEO ranking.
Browser Support and Adoption
JXL support is growing rapidly. Safari has native support, and Chrome/Firefox adoption is accelerating as web developers and browsers converge on this new standard. For projects targeting modern browsers, JXL is a smart choice; for sites requiring IE11 support or targeting very old devices, PNG or JPEG remain safer bets until JXL adoption becomes more universal.
Why Convert PNG to JXL Online
Superior Compression
JXL achieves 20-30% better compression than JPEG and 40-50% better than PNG for photographic images.
Best of Both Worlds
Support for lossless AND lossy compression in one format — choose the trade-off that suits each image.
Modern Format Features
HDR support, wide color gamut, transparency, and animation — all the features PNG and JPEG lack.
Future-Proof Delivery
Adopted by Safari natively; gaining Chrome and Firefox support rapidly — invest in the next-generation standard.
PNG vs JXL: Key Differences
| Feature | PNG | JXL |
|---|---|---|
| Released | 1996 | 2021 |
| Compression | Lossless LZ77-based, larger files for photographs | Superior lossy and lossless compression — 20-30% better than JPEG |
| Transparency Support | Full alpha-channel transparency | Full alpha-channel transparency |
| Animation Support | Not applicable — static image format | Supported with efficient modern encoding |
| Browser/Software Support | Universal across all browsers and platforms | Safari native support; Chrome/Firefox adoption growing; emerging standard |
| Best Use Case | Maximum compatibility and simple use cases | Modern web delivery, performance optimization, future-ready projects |
Where PNG and JXL Each Make the Most Sense
Email Attachments (Maximum Compatibility)
PNG's universal support means it works in every email client on every device, with no compatibility questions whatsoever.
Legacy Browser Compatibility
Older browsers and devices that don't yet support JXL need PNG's universal compatibility as a fallback.
Optimizing Images for Modern Web Pages
When you optimize images for a modern website targeting current browsers, JXL delivers 20-30% better compression than JPEG.
Ecommerce Product Galleries
Product photo galleries load faster in JXL, delivering the compression efficiency of AVIF without complex fallbacks.
Batch Converting to Download as a Zip
Convert an entire folder of PNG images to JXL and download the whole batch as a zip for modern distribution.
