Quick Start Compression
Open the HeronTool website and choose the needed tool. For example, with Image Compressor (图片压缩): drag in an image, adjust the quality slider, click "Compress," and download the optimized file. For PDF Compressor (PDF 压缩), upload a PDF, select a compression level (light/medium/heavy), and the system processes it automatically while preserving layout.
Code and Data Compression
Front-end developers can use JS Minifier (JS 压缩) and CSS Minifier (CSS 压缩) to remove whitespace and comments, and HTML Minifier (HTML 压缩) to slim down markup. For data APIs, JSON Minify (JSON 压缩) eliminates extra spaces to reduce transfer size. All tools support pasting code or uploading files, and output compressed results with one click.
Best Practices & FAQ
- Batch Processing: Image Compressor supports compressing multiple images at once to save time.
- Lossless First: For PDF, choose "light" compression to maintain clarity.
- Check Output: Always verify compressed files open correctly.
FAQ
Q: Can compression damage files?
A: Lossless compression preserves quality; lossy (e.g., high-quality image compression) may reduce sharpness. Choose as needed.
Q: Is there a file size limit?
A: Usually up to 50MB; see tool page for details.
Q: How to ensure code isn't broken?
A: Minifiers only remove non-harmful characters; test key functions after compression.
