FAQ
No. The compression engine runs entirely in your browser. Your file never touches our servers.
For 'Low' level, yes. For higher levels (Medium/High/Extreme), pages may be rasterized (converted to images) to maximize size reduction.
Since it works locally, the limit depends on your device's memory, but it handles most standard documents easily.
