Is TinyPNG safe to use?

Short answer

TinyPNG uploads your files to its servers.

When you use TinyPNG, your documents are transmitted over the internet to third-party servers for processing. You are trusting their retention, security, and privacy policies with your data — and once a file is uploaded, you cannot verify what happens to it.

The private alternative

Brevio runs every tool entirely inside your browser. Your files are never uploaded — they never leave your device. No account, no server, no retention. You can verify it yourself in the browser network tab.

Frequently asked questions

Does TinyPNG upload my images?

Yes. TinyPNG compresses images on its servers using pngquant. Brevio compresses images using the Canvas API in your browser — no upload.

Is TinyPNG better at compression?

For PNG files, TinyPNG's pngquant algorithm typically achieves higher compression ratios than Canvas API compression. For JPEG files, results are more comparable.
