The Best TinyPNG Alternative in 2026
TinyPNG is popular — but it uploads every image to their servers, only supports PNG and JPEG, and charges per image above the free limit. PicaPic is a privacy-first alternative that runs entirely in your browser, supports 4 formats, and does batch processing for free.
No account needed. Files never leave your device. Free to start.

🔒 Why "no upload" matters: When you compress images through TinyPNG, every file is sent to their AWS servers in the US. That means your images — product photos, client work, personal content — are transmitted and temporarily stored by a third party. PicaPic runs entirely in your browser using WebAssembly. Nothing ever leaves your device.
Why choose PicaPic?
- 100% browser-based — your images never touch any server, ever
- Convert to AVIF for up to 50% smaller files than TinyPNG's output
- Visual before/after slider so you can see quality before downloading
- Built on the same open-source Squoosh codecs used by Google
- Batch compress and download as a ZIP in one click
- Works offline once loaded — no internet required for compression
When TinyPNG is still a good choice
We'll be honest: TinyPNG has a higher free monthly limit (500 images/month vs PicaPic's 5/day) and a widely trusted brand. If you compress a few images monthly and don't care about privacy or format variety, TinyPNG is a fine tool.
But if you need privacy, AVIF support, batch ZIP downloads, or you compress images regularly, PicaPic is the better choice.
Try PicaPic now — no account, no upload, no compromise.
