Image Editor

This tool provides a private, browser-based image editor that performs editing entirely locally without server transmission. It solves the need to quickly resize, crop, rotate, and enhance photos while preserving original data. Target users include designers, marketing teams, social media managers, and content creators who require fast asset preparation, consistent export settings, and privacy-friendly workflows. When used in production, it supports batch edits and repeatable presets to accelerate recurring tasks.
Core Logic & Features: Required features include image upload or drag-and-drop, basic edits (resize in px, crop box, rotate, exposure, contrast, saturation, white balance), and export options for JPEG, PNG, WEBP. Optional/advanced features include batch processing, non-destructive history, export presets, color-management with sRGB, sharpening, noise reduction, and compression control. The tool applies edits to pixel data using standard canvas operations or WebGL where available, updating a preview and ensuring exported results reflect the final state.
Inputs & Outputs: Inputs: image file (types: image/jpeg, image/png, image/webp), size limit 50 MB, operations dictionary with keys: width_px, height_px, crop_rect, rotate_deg, exposure, contrast, saturation, white_balance, filter_id, output_format, quality. Outputs: edited image file and metadata: width_px, height_px, format, size_bytes.
Algorithms & Calculations: resizing uses bicubic-like interpolation; color adjustments operate on linear light space with gamma correction; export uses quality-based compression; history uses a stack of edits to support undo/redo.
Error & Edge Cases: invalid input format, image corruption, missing required inputs, memory constraints in large batches, browser limitations; when an input exceeds limits, the tool returns a structured error code in the API and does not crash.
Industry/Region & Localization: Units are pixels; color space is sRGB; no currency; privacy: images are processed locally, no automatic upload; localization: date/time not required.
Assumptions & Exclusions: Assumes modern browser with Canvas/WebGL support; excludes vector editing, batch asset management UI semantics, or server-based processing; no social features.
