How do I convert PNG to JXL using LetsConvert?

Upload your PNG file via drag-and-drop or file picker. Choose lossless mode if you want zero quality loss, then click Convert. Your JXL file is processed locally or on secure servers and is ready for download in seconds. Batch upload multiple PNGs for high-volume conversion.

Why should I convert PNG to JXL instead of staying with PNG?

JXL (JPEG XL) typically reduces file size by 40-60% compared to PNG with no quality loss in lossless mode, and it supports complex features like HDR, wide color gamut, and progressive decoding. This makes JXL ideal for high-res web images, mobile apps, and long-term archiving, despite some older browsers not supporting it yet.

Does PNG to JXL conversion preserve transparency, color profiles, and resolution?

Yes. The converter retains the alpha channel for transparency, embeds existing ICC color profiles (sRGB, Adobe RGB, etc.), and preserves the exact pixel dimensions. In lossless mode, no image data is altered; in lossy mode, you can control quality to balance file size. EXIF/XMP metadata is copied automatically.
