Both compress images. TinyPNG uploads your image to their servers, runs the compression there, and sends it back. PixlFits runs the compression entirely in your browser — your image never leaves your device. Here's a head-to-head.

When to choose PixlFits
Faster (no upload wait), unlimited, more output formats, GDPR-safe. PixlFits is the better choice when privacy or volume matters.
When to choose TinyPNG
Years of brand recognition. The compression algorithm is well-tuned, especially for PNGs. If you've already invested in their API for an automated pipeline, the integration is smooth.
Privacy comparison in plain English
When you use TinyPNG, your image travels over the internet to their servers (in the EU or US), gets stored temporarily (usually 1 hour, sometimes longer), and is processed there. The company has access to your file during that window. This is fine for memes and screenshots — it's not fine for ID photos, medical images, client work, or anything covered by GDPR / HIPAA.
When you use PixlFits, your image stays in your browser's RAM. You can verify this in DevTools → Network tab — there's no upload request. The processing happens via JavaScript Canvas API or WebAssembly running on your CPU.

Is TinyPNG safe for personal photos?
TinyPNG uploads your photo to their servers. They have a privacy policy, but the photo is technically out of your control once uploaded. For sensitive photos (IDs, medical, client work), PixlFits is safer because nothing is uploaded.
Is PixlFits as good as TinyPNG?
For 80%+ of image-processing tasks, PixlFits matches or beats TinyPNG on speed and is free without ads. For very specialized server-side features (e.g. AI super-resolution at 8x), TinyPNG may have an edge.
