Free Photo Editor

Purpose & User Intent: This tool provides a free, browser-based photo editor designed for photographers and hobbyists who need non-destructive editing, color grading, RAW support, and batch processing without installing software. It targets users handling multi-image workflows and seeks consistent output across sets.
Core Logic & Features: The system implements a non-destructive edit stack, adjustable controls (exposure, contrast, highlights, shadows, white balance, saturation), tone curves, color grading, lens corrections, noise reduction, and export presets. Required features include image import, an editable history, real-time previews, and export. Optional/advanced features include a presets library, batch processing, histogram visualization, local caching, and offline-like performance optimization.
Inputs & Outputs: Inputs are image files (JPEG, PNG, TIFF, RAW) and export settings (format, quality, resolution, color space). Outputs are edited image files in the selected formats, with optional metadata preservation. Algorithms & Calculations: Edits are applied via a non-destructive stack that preserves the original pixels; color space conversions between sRGB and Adobe RGB are performed; histogram-based adjustments, LUT-like color grading, sharpening, and noise reduction are applied.
Error & Edge Cases: Handles missing inputs by returning empty results; validates file types and sizes; gracefully handles large RAW files and memory constraints; ensures export requests are validated and honored where possible. Industry/Region & Localization: Aligns with standard imaging workflows; supports sRGB and Adobe RGB color spaces; uses ISO-based exposure considerations; privacy and data locality are emphasized, with client-side processing preferred. Assumptions & Exclusions: Assumes inputs are supported formats; excludes server-side editing pipelines, third-party plugins, and full RAW debayering beyond common formats; no licensing or watermark constraints implied.
