SVG compression works by removing unnecessary metadata, comments, hidden elements, and optimizing the XML structure. An SVG shrinker can minify coordinate values, simplify paths, merge duplicate elements, and remove unused definitions. SVGs are text-based, so compression can achieve 40-70% size reduction without any visual quality loss.

Compressed SVG files load faster on websites, reduce bandwidth usage, and improve page performance. Large SVG files with unnecessary code slow down rendering and waste storage. Using an SVG shrinker to compress SVG images reduces file sizes significantly while maintaining perfect scalability and quality - essential for icons, logos, and responsive web design.

Online SVG compression requires uploading files to external servers, risking privacy and requiring internet connection. Offline SVG shrinker tools like TinyFast compress SVG files directly on your Mac - faster, more secure, and work without internet. Offline compression keeps proprietary graphics private and delivers instant results, while online compressors expose your files and depend on server availability.

No! SVG compression is completely lossless. Unlike raster images, SVGs are vector-based, meaning compression only removes unnecessary code and metadata without affecting the visual output. A compressed SVG looks identical to the original at any scale. Modern SVG shrinker tools can reduce file sizes by 50-80% while preserving every visual detail perfectly.

SVG compression removes comments, editor metadata, unused definitions, hidden elements, default attribute values, and excessive whitespace. It also optimizes paths, minifies coordinates, converts colors to shorter formats, and merges redundant styles. All these removals make files smaller without changing how the SVG renders - perfect for web performance.
