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:
- The web tool allows 20 compressions per session; the API includes 500 compressions per month
- Files are uploaded to their servers — privacy concern for sensitive images
- Conversion limits depend on the current web tier
- Paid web tiers raise file-size, conversion, and folder limits
If you need more flexibility, better privacy, or different output formats, these alternatives deliver.
