Engineered for Extreme Media Workflows

Everything you need to automate, compress, and organize massive media collections locally.

Camera RAW & Photo Suite

Native LibRaw integration converts Sony, Canon, Nikon, and Fuji RAW files directly to WebP/AVIF with ICC color preservation and smart downscaling.

.ARW .CR3 .NEF .DNG WebP / AVIF

4K/8K Video & Hardware Acceleration

Auto-probes GPU hardware to encode via NVIDIA NVENC, Apple VideoToolbox, Intel QSV, AMD AMF, and VAAPI with 2-pass bitrate targeting.

NVENC VideoToolbox QuickSync H.264 / HEVC / AV1

Background Folder Watcher Daemon

Watches incoming directories using OS kernel event hooks (< 0.1% CPU). Auto-compresses files dropped into monitored folders with desktop toast notifications.

Windows Startup LaunchAgent systemd

Document & PDF Compression

Flate-decodes PDF structural content streams, removes redundant orphan cross-reference tables, and re-encodes scanned pages with optimal DPI scaling.

Stream Deflate DPI Downsampling Font Deduplication

Animated GIF & WebP Engine

Adaptive P-mode palette quantization solves GIF memory overflow and converts heavy legacy GIFs into modern animated WebP/MP4 files up to 90% lighter.

P-Mode Fixed Octree Quantization Animated WebP

Zero-Leak Queue & Safety Gate

Streamed file scanning processes 100,000+ files with constant bounded RAM. "Only Save If Smaller" protection ensures files never grow in size.
