Local DOM Processing
Resizing occurs strictly inside your browser using the HTML5 Canvas API. This prevents bandwidth consumption, guarantees zero latency, and ensures your private files never touch a remote server.
Smart Aspect Ratios
When batching images of different orientations (portrait vs. landscape), using the "Target Width" or "Target Height" modes forces uniformity on one axis while perfectly calculating the other to prevent image warping.
Lossless ZIP Archiving
To avoid crashing the browser with hundreds of individual download prompts, the processed images are buffered into memory and instantly compressed into a single, standardized ZIP archive.
