Key Features
Compress to a Target Size
Set an exact target size — for example 2 MB for an email attachment — and PDF JustFit searches for the best available quality that fits. Four one-tap presets (Light, Balanced, Strong and Extreme) cover the common cases, and Smart mode keeps text, fonts and structure selectable.
Conversion
Convert between PDF, images and text, so a document can move between formats without a desktop tool.
On-Device Assistant
Ask questions about a document and get answers from an assistant that runs on the device. Files are not uploaded to a server, and no account is required.
