Online Photo Editor

Purpose: A browser-based photo editor that enables quick image edits without installing software. Users include students, freelancers, marketers, social media teams, and small businesses who need fast changes to images for posts, thumbnails, or documents. When used: during content creation, last-minute adjustments, or when desktop apps are unavailable. Core logic: supports non-destructive edits (undo/redo) via in-browser processing, with operations such as crop, resize, rotate, brightness, contrast, saturation, and color filters; export to PNG, JPG, or WEBP; privacy-first design. Outputs: edited image file and metadata, with chosen format and quality. Algorithms: uses standard pixel operations: cropping maps coordinates, rotation via affine transform, brightness/contrast/saturation/sharpness via linear or curve transforms, and filters via convolution or color-matrix. Edge cases: invalid image types rejected, large files may trigger memory limits, and unsupported exports gracefully fall back to a known format. Localization: follows ISO image formats and uses metric-based crop dimensions; no region-specific content beyond language. Assumptions: client-side processing by default; no RAW or professional color management; no cloud storage by default; single-image edits per operation.
