pingo optimizer
pingo, a fast image optimizer
pingo is an experimental, fast web image optimizer which offer lossless, web lossless or lossy compression. it performs image reductions over iterations thanks to recursive multi-processing and multithreading systems
version:
0.99 [beta 30] — 64-bit — windows (zip)overview
| auto optimizer for Web | convert PNG or JPG to sRGB |
| do image compression automatically | CMYK JPG — iCCP/ICC color or gray |
| WebP optimizer | APNG optimization |
| optimize WebP, or convert PNG/JPG to WebP | optimize animated PNG losslessly or lossy |
| image transformations | clean all private data |
| auto-rotation, grayscale, scaling, no trans | remove private or useless data from images |
about
| highly optimized speed — compression | multiprocessing — multithreading |
| palette sorting, advanced filters, SIMD opt. | process multiple files and multiblocks comp. |
| multiple adaptive lossy | targets high quality |
| set lossy filtering, quantization or paletted | detect JPG quality, no color differences |
| management of some corrupted files |
| try to handle corrupted files automatically |

important
always do backup before using pingo. try on test files/folders especially made for this. understand that this tool is processing all files in subfolders. it could convert/reduce the visual quality of your files and overwrite them without any backup or warning
