TinyPNG
Smart PNG and JPEG compression that reduces file sizes by up to 80% while preserving quality.
Best for developers who need automated image compression in their build pipeline or CI/CD.
Use Cases
Free Tier
500 images/month via API, unlimited via web interface
How to Maximize the Free Tier
TinyPNG's API (500 images/month) is best integrated into your build pipeline for automatic compression before deployment. For higher volumes, use the free web interface which has no limits — just drag and drop files. TinyPNG only handles PNG and JPEG; for WebP or AVIF conversion, pair it with a tool like Squoosh or Sharp in your build script. The up-to-80% compression ratio means smaller pages, faster load times, and lower CDN costs.
Getting Started
Drag and drop to tinypng.com for instant compression (free, unlimited). For API: sign up → get API key → install client → `tinypng API_KEY input.png -o output.png` → integrate into build pipeline. 500 images/month via API.
Pros
- Compression ratio: Reduces PNG and JPEG file sizes by up to 80% with minimal perceptible quality loss
- API pipeline: REST API enables automated compression in build scripts, CI/CD pipelines, and serverless functions
- Web interface: The web interface is completely free and unlimited — no registration needed for manual compression
Cons
- API quota: Only 500 images/month via the API — insufficient for sites that process large volumes of user uploads
- Format limited: No SVG, WebP, or AVIF support — only PNG and JPEG compression with no format conversion
- Compression only: No CDN, no delivery, no storage — it's a compression tool, not a media management platform
