About PBM
Portable Bitmap
The 1-bit black and white member of the Netpbm family: uncompressed pixels after a short text header. Use it as monochrome input for tools such as potrace and fax or OCR utilities.
About JXL
JPEG XL
An image format standardized as ISO/IEC 18181 in 2022, with lossy and lossless modes, HDR and alpha. It can repack an existing JPG losslessly into a file about 20 percent smaller. Use it for archiving photos or for apps that support it; browser support is limited, so check before using it on the web.
