Why Look for TinyPNG Alternatives?
TinyPNG is one of the most well-known image compression tools, but it has significant limitations that make it frustrating for regular use:
- 20 images/month limit on the free plan — easy to hit if you're managing a website or social media
- Uploads your images to TinyPNG's servers — a privacy concern for sensitive or confidential images
- Only compresses PNG and JPG — no WEBP conversion, no resizing, no other tools
- 5MB file size limit on the free plan
- No quality control — automatic compression with no slider to adjust
The good news: there are excellent free alternatives that have none of these limitations.

Frequently Asked Questions
Why is TinyPNG so popular if it has limits?
TinyPNG was one of the first easy-to-use online image compressors and built a strong reputation for quality. Its simplicity and good compression results made it the go-to recommendation for years. However, its 20 images/month limit and server upload requirement make it less ideal compared to modern browser-based alternatives.
Is it safe to use TinyPNG?
TinyPNG is a legitimate service, but it does upload your images to their servers for processing. For sensitive images (personal photos, confidential product images, etc.), browser-based tools like PixelTools or Squoosh are safer since your images never leave your device.
What is the best free TinyPNG alternative?
PixelTools is the best free TinyPNG alternative for most users: it's completely free with no limits, processes images in your browser (no upload), and includes 18 additional tools beyond compression. Squoosh is the best alternative if you need advanced codec options like AVIF.
Does PixelTools compress images as well as TinyPNG?
Yes. Both use similar JPEG and PNG compression algorithms. The quality difference is negligible at equivalent settings. PixelTools gives you a quality slider for precise control, while TinyPNG uses automatic compression.
Can I use these tools for commercial projects?
Yes. All tools listed here can be used for commercial projects. PixelTools, Squoosh, and TinyPNG (within limits) are all suitable for professional use.
