How It Works & Features
By utilizing your browser's native capabilities, this tool provides fast, private, and secure image resizing. It natively scales and re-encodes images without the need for external APIs.
- Batch Processing & ZIP Export: Drag and drop multiple files to process them simultaneously. Click Save All to download your resized images securely packed in a single ZIP file.
- Pixel & Percentage Scaling: Switch seamlessly between exact pixel dimensions and percentage-based scaling (e.g., 50% or 200%) using the built-in presets or manual inputs.
- Aspect Ratio Locking: Easily lock the aspect ratio to prevent stretching. Updating one dimension will automatically calculate the perfect proportional opposite.
- Visual Preview & Fullscreen Mode: Verify your scaled output instantly. The tool gives you a live visual confirmation, and you can click Fullscreen to expand the workspace and thoroughly inspect the image before saving.
- Browser-side Privacy: We use native image rendering and canvas features running directly in your web browser. This ensures no data transfer, instant speed, and absolute privacy.
