Converseen
What it is
Converseen is a free batch image processor for Windows, Linux, macOS, FreeBSD, and other operating systems. It converts, resizes, rotates, flips, and compresses images, and can rename groups using progressive numbers or prefix and suffix values. ImageMagick lets it handle more than 100 formats, including DPX, EXR, GIF, JPEG, JPEG-2000, PNG, SVG, TIFF, WebP, and HEIC/HEIF. It can convert a full PDF or selected pages into images at chosen dimensions and formats, and extract images from Windows icon files. Built with open-source frameworks and libraries such as Qt and ImageMagick, its source code is released under GNU GPL version 3. Linux installation options include source code, AppImage, Snap, Flatpak, and distribution repositories. Converseen does not transfer information to other networked systems. Windows and Linux users need Ghostscript configured for PDF processing. The macOS release is beta and is not currently codesigned.
