GraphicsMagick vs Photopus

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.

Photopus is Windows software for batch photo editing, including conversion, resizing, renaming, watermarking, transformation, and touch-up. Its batch mode can edit hundreds of photos. The product supports more than 90 image formats, including RAW camera images, and maintains image metadata after processing. Editing tools include text and image watermarks, rotate, flip, crop, color adjustments, and effects. It can create multi-page PDF or TIFF files from multi-page images. The free edition is listed for Windows 7, 8, 10, and 11. Photopus Pro costs 19.95 USD once and includes one year of free upgrades and a 30-day money-back guarantee. The edition comparison lists PDF and multi-page PDF, PNG, RAW camera formats, and additional formats among Pro features, so format availability depends on the edition. The Pro evaluation trial expires after 9 executions. Listed requirements are a 1 GHz CPU, 1 GB RAM, and 100 MB disk space. The maker offers email support and does not regularly provide telephone support.
