Frequently asked questions

Is my PDF uploaded?

No. The selected PDF is processed inside this browser tab.

Will compression always make it smaller?

No. Some PDFs are already efficiently encoded. Kinumia reports the real result instead of claiming savings that did not happen.

Kinumia Scan brings scanning, OCR, organization and private PDF tools directly to your phone.
