Frequently Asked Questions

Why look for a TinyPNG alternative?

TinyPNG is great for occasional use, but has limitations: 20 images/month (free), 5MB file size limit, upload/download wait times, and $25/year for 500/month. If you compress images regularly or need batch processing, desktop alternatives offer better value.

What's the best free TinyPNG alternative?

Diwadi is the best free alternative - unlimited images, unlimited file sizes, no monthly caps, 25x faster batch processing, 100% private, and free. No limitations or upsells.

Are desktop compressors better than online tools?

For regular use, yes. Desktop tools like Diwadi are 25-70x faster (no upload/download), 100% private (local processing), and have no file size or monthly limits. Online tools are convenient for one-time compression of 1-5 small images.

Can I switch from TinyPNG to Diwadi easily?

Yes! If you can use TinyPNG, you can use Diwadi. Install (30 seconds), drag images, choose compression level, click compress. Done. Same simplicity, but unlimited and faster.

What if I need to compress large files (>5MB)?

TinyPNG rejects files >5MB. Desktop alternatives like Diwadi and ImageOptim have no file size limits. Diwadi can compress 50MB+ RAW conversions and high-res photos without restriction.

Is compression quality the same across tools?

Yes! Most tools use the same underlying algorithms (pngquant, mozjpeg, etc.). TinyPNG, Diwadi, ImageOptim all produce excellent quality. The difference is speed, limits, and convenience.

Do any free alternatives match TinyPNG's quality?

Yes! Diwadi, ImageOptim, and Squoosh all produce quality comparable to TinyPNG. They use the same or similar compression algorithms - the difference is in features, limits, and speed.

Can I use multiple tools together?

Absolutely! Many users keep TinyPNG for quick single-image optimization on the go, and use Diwadi for bulk work (90% of tasks). Use what works best for each scenario.
