Format description
JPEG XL (or JXL) is a new image format with better compression than other image formats like legacy JPEG, PNG, WebP, AVIF and others. Designed for the modern web and with professional photography in mind, JPEG XL offers a more efficient way of storing images. In addition to supporting alpha channels/transparency, lossless, progressive loading and animations, the new image format promises high speed encoding and decoding even on phones.JPEG XL has experimental support in Firefox, Chrome and other Chromium-based browsers like Edge. For now, you need to enable a feature flag for the browsers to display JXL images.
MConverter’s conversions from JPEG XL are lossless, so there is no reduction in the quality of your images.
When converting from JPG or GIF to JXL, the quality is mathematically lossless. In all other cases when converting to JXL, the image quality is kept visually lossless. Your images will look visually identical.

Is converting JXLs safe with MConverter?
For cloud-based conversions, MConverter encrypts your JXL files using the latest technologies, such as TLS 1.3 and HSTS. They are transmitted securely to our cloud service provider’s EU-based data center, which holds internationally recognized ISO 27001 and SOC 2 certifications. There, each conversion is processed in a separate, isolated environment. This technique further reduces the risk of a malicious file impacting other conversions.
Four hours after the conversion is complete, your files are automatically deleted from MConverter’s systems. You can also permanently delete your JXLs and other converted files immediately after finishing the conversion with the trash icon.
When converting on-device, your files never leave your device. MConverter processes them locally. Note: on-device conversions are not yet available for some hardware-intensive formats.
For both cloud and on-device conversions, your files are never scanned or shared with third parties for marketing purposes.

How long does it take to convert JXL?
