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.
1. QuickShrink (Best for Privacy)
Price: Free (5 images/day) | Pro $4.99/mo
Website: quickshrink.orthogonal.info
Key advantage: 100% browser-based. Your images never leave your device. Zero uploads, zero server processing.
- Supports PNG, JPEG, WebP output
- Adjustable quality slider
- Instant results — no waiting for server response
- No account required
Best for: Designers and developers who handle client assets or sensitive images and don't want them on third-party servers.
2. Squoosh (Google)
Price: Free
Website: squoosh.app
Google's open-source image compressor. Also browser-based with side-by-side preview. Excellent for single images but no batch processing.

The Verdict
If privacy matters (and it should — especially with client work), QuickShrink is the strongest TinyPNG alternative. Your images stay on your device, compression happens in-browser, and it's fast.
For power users who need codec-level control, Squoosh is excellent but limited to one file at a time.
