FAQ

Can I compress a 50MB PDF down to 100KB?

Depending on the image content, our WASM engine will heavily compress visual data and remove hidden metadata to get as close to 100KB as physically possible.

Is it really 100% private?

Yes. All compression happens directly inside your browser. Your PDF is never uploaded to any server.

Will the text become blurry?

No, vector text and fonts remain razor-sharp. Only embedded images are compressed to hit the 100KB target.
