Professional Features
Everything you need for rapid RAW photo culling and processing, built directly into your browser without sacrificing performance or privacy.
Lightning Fast Performance
No server uploads. Cull-Pro works locally in your browser, decoding CR2, DNG, TIFF, and other RAW images instantly. Skip the latency of cloud-based editors.
100% Privacy & Security
Your photos never leave your device. All processing, cropping, and adjustments are handled locally via WebGL and WebAssembly, ensuring maximum client privacy.
Offline-Ready Sessions
Pick up where you left off. Cull-Pro safely saves your workspace sessions, ratings, and edits directly to IndexedDB so you can work entirely offline.
Broad Format Support
Seamlessly open Canon RAW (.CR2), Adobe Digital Negative (.DNG), TIFF, JPEG, and WebP formats. Review high-resolution previews or precise uncompressed data.
Non-Destructive Editing
Apply curves, contrast, exposure adjustments, and visual profiles without mutating your original RAW files. Export stunning JPEGs or apply adjustments in bulk.
Advanced Cropping
Use touch-friendly, aspect-ratio locked cropping tools right within the cull viewer. Prepare your composition perfectly before exporting your final select.
The Engine Under the Hood
Native WebAssembly Decoding
Unlike traditional web apps that rely on servers to process images, we utilize compiled WebAssembly modules (like raw.js) to decode massive camera sensor data directly efficiently using your CPU. This provides near-native desktop speeds inside any modern browser.
GPU-Accelerated Filters
When you adjust exposure, curves, or apply color profiles, we map those instructions to native CSS and Canvas API filters. This means your graphics card does the heavy lifting, ensuring a fluid 60fps editing experience without frustrating lag.
