- New: JPEG XL — open .jxl files and convert them to anything, or save your images as JPEG XL. - New: Lossless JPEG to JPEG XL — the file gets smaller without losing a pixel, and converting it back gives you the exact original JPEG. - New: Subtitles to Word and text — turn SRT and VTT files into a DOCX or TXT transcript, with or without timestamps. - Fixed: FLAC and OGG now convert to MP3, WAV, AIFF and Apple Lossless, any file converts to Opus, and mono recordings to OGG — these used to fail. AAC files are now standard .aac files.
