Quick Start
On HeronTool, the optimize tools focus on reducing file size without significant quality loss. Visit Image Compressor to upload images, supporting JPG, PNG, WebP. Click "Compress" to auto-process, then download. Default settings suit most cases, but you can adjust compression level (0-100); lower values reduce size, but beware of artifacts.
SVG & Web Asset Optimization
For vector graphics, use SVG Optimizer. Upload SVG files; the tool removes redundant metadata, comments, and invalid attributes, simplifying paths. Enable the "Pretty" option to keep readability, or disable for compact code. To compress PDF documents (e.g., embedded manuals), use PDF Compressor, supporting batch upload while preserving bookmarks and links.
Advanced Tips
When optimizing web assets, first compress images (usually 80% of size), then optimize SVG icons, and finally compress PDFs for integration into HTML. Use HeronTool's "Compare" feature to see size differences. Keep original image dimensions to avoid blur from rescaling. All tools support drag-and-drop upload; processing happens locally in your browser, ensuring privacy.
