PDFs are processed on your device, never uploaded.
Email attachments, application portals and government forms often cap PDFs at a few megabytes — and a scanned or photo-heavy PDF blows right past that. A PDF compressor optimizes the images inside the document so the file shrinks while the text stays crisp and readable.
ConvertEase compresses PDFs entirely on your iPhone. Pick a compression level, and it rebuilds the file smaller in seconds — no uploading a private document to a website, no watermarks, no page limits, and it works offline.
