Choose one PDF or several PDFs, compress them, review the result, then save or share the new compressed copy. Before compression, the app also checks whether there is enough available storage to create the output safely. Highlights: β€’ On-device PDF compression β€’ PDF files are not uploaded to our servers β€’ Original files remain unchanged β€’ Save to Files, share, or preview compressed PDFs β€’ Batch PDF compression support β€’ Free users can process 2 PDFs per day β€’ Free limits: up to 50 MB for one PDF, or 2 PDFs / 100 MB total per batch β€’ Premium unlock: larger PDFs up to 1.5 GB, batches up to 75 PDFs, and no daily PDF limit β€’ No account, no ads, no ad tracking PDF processing works offline.
