Photo Editor Free

Purpose and users: This tool provides browser-based photo editing for freelancers, marketers, educators, and small teams who need fast image refinements. Common scenarios include resizing for social media, cropping for banners, and color corrections for product photos. The goal is immediate, shareable results without desktop software.
Core logic & features: The editing pipeline ingests an image, applies a sequence of edits, and renders a final asset. Required features include image upload, crop/resize/rotate, brightness, contrast, saturation, color temperature, and optional sharpness or blur. Output formats JPEG, PNG, and WEBP with quality controls. Advanced options may include AI auto-enhance, aspect-ratio presets, and basic non-destructive edits.
Algorithms & calculations: Cropping uses coordinates; resizing uses bicubic interpolation; rotation applies a 2D affine transform; brightness/contrast/saturation map input deltas to linear adjustments; color temperature modifies white balance; encoding quality governs compression. Outputs preserve transparency for PNG and WEBP where supported.
Error & edge cases: Invalid image files, unsupported formats, or extreme dimensions may fail gracefully with error codes. Non-destructive history is limited to a short undo history; large files may require more memory.
Industry/region & localization: Uses sRGB color space and standard web export formats. Units are pixels; no currency or locale-specific adjustments are required.
Assumptions & exclusions: Does not support RAW editing or layered compositing; no advanced masking, HDR, or 3D features. No watermarking or DRM features.
