In their own words
Converseen
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 renames groups using progressive numbers or prefix and suffix values. Through ImageMagick, it handles more than 100 formats, including DPX, EXR, GIF, JPEG, JPEG-2000, PNG, SVG, TIFF, WebP and HEIC/HEIF. It can turn a full PDF or selected pages into images with chosen dimensions and formats, and extract images from Windows icon files. Converseen is built with open-source frameworks and libraries including Qt and ImageMagick; its source is released under GNU GPL version 3. Linux installation options include source code, AppImage, Snap, Flatpak and distribution repositories. The program does not transfer information to other networked systems. The Free plan is free. Windows and Linux users need Ghostscript configured for PDF processing, and the macOS release is beta and not currently codesigned.
Pillow
Pillow is a free, open-source Python library for opening, editing, and saving image files. It can identify and read more than 30 raster formats, while its write support is narrower and covers common interchange and presentation formats. Its documented operations include image processing, color transforms, enhancement, geometric transforms, and image sequences. Pillow supports current Linux, macOS, and Windows systems; its version 12 support table covers Python 3.10 through 3.14. The project documents installation with pip using `python3 -m pip install --upgrade Pillow`. JPEG and zlib are required by default for source builds, while WebP, JPEG 2000, color management, and complex text layout rely on additional libraries. The project flags parsing untrusted image data as its primary attack surface and recommends safeguards including format allowlists, input limits, and sandboxing. Pillow uses the MIT-CMU License. Development and technical discussions are directed to GitHub, Stack Overflow, and Gitter; the core maintainers are volunteers. Commercial support and maintenance are available through a Sonar Subscription.
