Note: source files are immediately extracted to temporary subdirectories which allowsīrowsing/editing content before converting. With 50% resampling from 1920px output files are typically 10 times smaller than source.Īpplication is native and portable, settings are stored in local ini file, thereĪre no dependencies on any runtime framework or non-standard dlls (except for those Source with subjectionably neglectable quality loss. output: zip (cbz) with no compression (copy mode).ĭepending on resampling used output files are at least 2.5 times smaller than.

optional image resampling (percentage),.dozens of formats available since version 0.9 thanks to ImageMagick (including AVIF, JPEG XL, FLIF - your reader would be actual limitation and WebP might be still leading due to compatibility),.

initially: conversion to WebP format with libwebp (typically 2-3 times smaller image sizes),.

source: any format recognized by 7-zip (zip, rar, tar, 7z = cbz, cbr, cbt, cb7 respectively),.

Helper utility for cbz/cbr files (comic books mostly) content scaling and converting to WebP (as default) format:
