Photo Format Converter is a desktop batch image conversion, vector rasterization, geometric transformation, and color mode normalization utility for Linux. An independent Linux desktop alternative to XnConvert for batch image format conversion, it handles raster and vector inputs with alpha matte compositing, multi-size icon packaging, DPI metadata tagging, and before/after pixel inspection.

Key Features:

• Multi-Format Batch Queue: Converts between PNG, JPEG, WebP, TIFF, BMP, multi-size ICO (16..256), PPM, and GIF, while rasterizing SVG, SVGZ, and XPM inputs via Qt vector rendering with user-chosen matte compositing for non-alpha target formats.
• Geometric & Color Mode Pipeline: Applies EXIF orientation normalization, 90/180/270 or custom angle rotation, horizontal/vertical flips, aspect-preserving resize or fit-box letterbox padding, RGB/RGBA/8-bit Grayscale/1-bit Dithered B&W/CMYK color normalization, custom DPI metadata (72/150/300/600), and templated output filenames.
• Before/After Preview & Throughput Log: Displays side-by-side transformed previews with pixel mode, bit-depth, DPI, and file size telemetry plus CSV and JSON manifest export.
