Free TinyPNG Alternative (No Upload, No Signup)

TinyPNG is a well-known image compressor, but it typically uploads your files to its servers and free use often comes with a monthly image limit. If you want fast PNG and JPG compression without any of that, 325Tools is a free, private alternative that runs entirely in your browser.

Why choose 325Tools over TinyPNG

• No upload. Your images are processed locally — they never leave your device. TinyPNG typically uploads every file to the cloud.
• No signup. Use every tool immediately, with nothing to install.
• No monthly limits. There's no "you've used your free images this month" wall.
• More than compression. Resize, convert formats, and more — bundled with 160+ other tools.

How to switch

1. Open the tool you need above — for example Image Compressor.
2. Drop in your images. They stay on your device.
3. Download the smaller files. No account, no limit, no waiting.

That's the whole workflow — a faster, more private replacement for TinyPNG.
