GraphicsMagick vs Pixillion Image Converter

GraphicsMagick is free image-processing software with command-line tools, programming interfaces, and graphical interfaces for image conversion, editing, and 2D vector rendering. It can resize, rotate, sharpen, reduce colors, apply effects, compare and composite images, create montages and GIF animations, and draw shapes or text. It reads, writes, and manipulates images in more than 92 major formats, including AVIF, GIF, HEIC, JPEG, JPEG-2000, JXL, PNG, PDF, TIFF, and WebP. The software also supports very large images, including gigapixel-size files. OpenMP multi-threading can scale CPU-bound processing across processor cores when built with a compatible compiler. Interfaces include C, C++, Lua, Perl, PHP, Python, Tcl, Ruby, Windows .NET, and Windows COM, alongside the command line. Some format support relies on external components, such as Ghostscript for PDF and PostScript or dcraw for camera RAW formats. GraphicsMagick is distributed under an MIT-style license for open-source, proprietary, or GPLed applications. The project lists version 1.3.48, released July 23, 2026, as current and recommends updating because significant issues are addressed in almost every release.

Pixillion Image Converter is a Windows and macOS desktop tool for converting image files between formats including JPEG, PNG, GIF, PDF, BMP, RAW, PSD, ICO, and HEIC. It can batch-convert or compress photos, rotate and resize them, add captions, watermarks, or logos, and update image metadata. Before conversion, it previews images and shows format, compression settings, and resize dimensions. The product page says conversion is available from the right-click menu. Pixillion preserves vector graphics when converting between vector formats, and its listed formats include SVG, TIFF, AVIF, WEBP, EPS, HEIF, DNG, CR2, and others. The free version is for non-commercial use, never expires according to the maker, and costs nothing. Pixillion Plus is the paid professional version, with no price listed. NCH provides tutorials, a manual, a forum, bug reporting, and technical support. NCH says the current version works on 64-bit Windows 11, 10, 8, 7, and Vista; the versions page lists Pixillion 14.00 for macOS, uploaded August 20, 2026. Purchases older than six months may require an upgrade purchase for the current version.
