picopt is a multi format lossless image optimizer that uses external tools.
picopt will optionally drop hidden timestamps at the root of your image directories to avoid reoptimizing images picopt has already optimized.
Note the software transforms images in place and discards the old image. Always have a backup of images before running picopt in case you are not satisfied with the results.
This is free and open source software.
Formats supported:
- By default picopt will optimize GIF, JPEG, PNG, and WEBP images.
- Optionally optimize SVG images, ZIP, ePub, and CBZ containers.
- Convert many lossless images such as BMP, CBR, CUR, DIB, FITS, GIF, IMT, PCX, PIXAR, PNG, PPM, PSD, QOI, SGI, SPIDER, SUN, TGA, TIFF, XBM, and XPM into PNG and WEBP.
- Convert Animated GIF, TIFF, and FLI into Animated PNG or WebP files.
- Convert Animated GIF, TIFF, FLI, and PNG into Animated WebP files.
- Convert MPO to JPEG by stripping secondary images (often thumbnails created by cameras) if a primary image exists. (Experimental).
- Convert RAR files into Zipfiles and CBR files into CBZ files.
- Support for preserving EXIF, ICC_PROFILE, and XMP data across optimization and conversion.
- Internal oxipng replaces external optipng for PNG compression.
