TinyPNG and compresspngfile.com are two of the most popular free online PNG compression tools. Both use smart lossy compression to dramatically reduce PNG file sizes. But which one is actually better for your needs?
We ran head-to-head tests on both tools to give you a definitive comparison.

Compression Quality Test Results
We compressed 5 different PNG file types on both tools and recorded the results:

|---|---|---|---|---|
| Logo (transparent) | 485 KB | 148 KB (69%) | 89 KB (82%) | compresspngfile.com |

File Size Limit Comparison
This is one of the biggest practical differences between the two tools.
| Scenario | TinyPNG | compresspngfile.com |
|---|---|---|
| 3 MB product photo | ✅ Works (under 5 MB) | ✅ Works (under 20 MB) |
| 8 MB high-res PNG | ❌ Fails (over 5 MB free limit) | ✅ Works |
| 15 MB RAW export | ❌ Fails | ✅ Works |
| 20 MB design export | ❌ Fails | ✅ Works |
TinyPNG's 5 MB free limit is a significant restriction for photographers, designers, and anyone working with high-resolution PNG files. compresspngfile.com's 20 MB limit handles virtually all use cases.
Privacy Comparison
| Privacy Factor | TinyPNG | compresspngfile.com |
|---|---|---|
| Server upload | Yes — files uploaded to TinyPNG servers | Yes — files uploaded to secure servers |
| Storage duration | Stored temporarily (hours) | Auto-deleted after download |
| Third-party sharing | Not explicitly disclosed | Never stored or shared |
| HTTPS | Yes | Yes |
