Batch PNG, JPEG & WebP optimizer with Target-KB fit & split loupe
Image Size Optimizer is a desktop batch image compressor, palette quantizer, Target-KB auto-fitter, and interactive split-preview analyzer for Linux. An independent Linux desktop alternative to Caesium Image Compressor for batch image optimization, lossless and lossy encoding, and side-by-side quality checks.
Key Features:
- Batch PNG, JPEG & WebP Compression: Quantizes RGBA PNGs via Fast Octree and RGB PNGs via Median Cut (16 to 256 colors) with level-9 zlib compression, encodes progressive JPEG with configurable 4:4:4, 4:2:2, or 4:2:0 chroma subsampling and EXIF metadata removal, and supports both lossy and lossless WebP output.
- Target-KB Auto-Fit & Lanczos Scaling: Runs binary search across JPEG/WebP quality or PNG palette color counts to fit within a strict file-size budget, with optional Lanczos maximum-dimension scaling and real PSNR (dB) measurement.
- Interactive Split Before/After & 4x Pixel Loupe: Compares original and compressed pixels side-by-side with a draggable vertical curtain and real-time 4x zoom loupe.
- Multi-Format Preset Benchmark: Evaluates six presets (PNG-256, PNG-64, JPEG Q85, JPEG Q70, WebP Q80, WebP Lossless) in memory with encode timings and size charts, plus batch folder export and CSV/JSON reporting.
