Looking for a TinyPNG alternative that's free, private, and doesn't require uploads? Here are the best options in 2026 — including one that compresses images entirely in your browser.

Why Look Beyond TinyPNG?

TinyPNG is great, but it has limitations:

Free tier limited to 20 images/month via API (500 via web)

Files are uploaded to their servers — privacy concern for sensitive images

No WebP output from the free web tool

Pro pricing starts at $25/year

If you need more flexibility, better privacy, or different output formats, these alternatives deliver.
