Tinypng
TinyPNG is an image compression service that reduces the file size of PNG, JPEG, and WebP images with smart lossy compression while aiming to keep visual quality high.
Key takeaways
- TinyPNG reduces image file size by up to 70% with minimal quality loss
- Supports PNG, JPEG, and WebP formats
- Free for up to 20 images per upload (5 MB each)
- Integrates with WordPress and developer workflows via API
- Compression alone is not a substitute for proper image sizing or responsive images
For SEO practitioners, smaller images can improve page speed, reduce bandwidth, and support better Core Web Vitals performance.
