Why Client-Side Image Compression Protects Privacy
Standard online image converters transmit your images over the internet to remote servers for processing. For sensitive product screenshots, identity documents, or proprietary creative assets, uploading files introduces unnecessary privacy risks.
With the OpenTools Image Compressor and Converter, image processing executes directly in your browser tab using native HTML5 Canvas and browser image codecs. Your images never touch an external server, and files are saved directly to your local downloads folder.
Supported Formats and Compression Controls
The optimizer supports JPEG, PNG, and WebP formats. You can adjust output quality and resize dimensions before exporting:
- Format Conversion: Convert uncompressed PNGs or large JPEGs to modern, lightweight WebP files.
- Quality Adjustment: Tune lossy compression quality to strike the right balance between file size and visual fidelity.
- Dimension Scaling: Resize high-resolution assets for web publishing without installing heavy desktop photo editors.
