Frequently Asked Questions
How is this different from TinyPNG?
TinyPNG uploads your photos to external servers to execute compression algorithms. Privacy-First Toolbox executes image compression directly in your browser using HTML5 Canvas and WebAssembly. Your photos never leave your device.
Can I compress files larger than 5MB?
Yes. Unlike TinyPNG which cuts off free users at 5MB, Privacy-First Toolbox allows up to 50MB per file because there are no server bandwidth constraints.
