JPEG XL and PNG are both capable of lossless compression, but they occupy very different positions in the ecosystem. JXL achieves dramatically better lossless compression — often 35-50% smaller than PNG — while supporting features PNG lacks, such as lossy mode, HDR, animation, and progressive decoding. PNG, however, is the established lossless web image format with complete support in every browser, image editor, and operating system since the late 1990s.
Converting JXL to PNG produces a universally compatible lossless image file. For lossless JXL sources, the conversion preserves every pixel exactly. For lossy JXL sources, the decoded image is stored losslessly in PNG, freezing whatever quality the JXL encoding produced without any further degradation. This makes PNG an excellent archival format for decoded JXL content.
PNG enjoys near-perfect compatibility across every platform. All web browsers render PNG natively, every image editor imports PNG without plugins, and every operating system displays PNG thumbnails and previews. JXL, despite being technically superior, lacks this universal support. Converting to PNG ensures your images are accessible to every recipient without requiring them to install new software.
PNG is also the standard format for graphics with sharp edges, text, transparency, and flat colors — icons, screenshots, UI mockups, diagrams, and logos. If your JXL files contain this type of content, PNG preserves them with pixel-perfect fidelity and full alpha transparency support. Web developers commonly need PNG for favicon generation, sprite sheets, and progressive enhancement fallbacks.
The converter decodes the complete JXL bitstream and encodes the pixel data as a PNG file with optimal compression (zlib level 9 by default). Alpha channels from the JXL source are preserved as PNG alpha transparency. JXL's wide color gamut data is converted to sRGB by default, with the ICC profile embedded in the PNG. For lossless JXL sources, the conversion is mathematically lossless within the sRGB color space. 16-bit JXL images are downsampled to 8-bit per channel for standard PNG output.
For lossless JXL sources, the PNG output is pixel-perfect — every color value is identical within the 8-bit sRGB space. For lossy JXL sources, the PNG stores the decoded lossy image losslessly, preserving whatever quality the JXL encoding produced without adding any compression artifacts. PNG is the gold standard for lossless raster image storage.

JXL to PNG conversion trades compression efficiency for universal compatibility and lossless fidelity. PNG is the safest choice when you need a JXL image to be accessible on every platform without quality loss.
