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.

Format description

PDF is an acronym for Portable Document Format. It was created for presenting documents with formatted text, graphics, and other form elements in a way that is independent of the user's operating system and software. It is based on the PostScript language. PDF files can be password-protected and encrypted.
PDFs can also be edited by converting them to a Microsoft Office Word format like DOCX, then back to PDF.
