Frequently asked questions

How much can PDF compression reduce a file?

The reduction depends on image resolution, embedded fonts, duplicate objects, and stream structure. Text-heavy PDFs often shrink less than scan-heavy PDFs with large images.

Does compression make a PDF blurry?

Lossless mode avoids image quality changes. Quality-based profiles may downsample or recompress images, so choose the balanced profile when readability matters.

Can I compress a PDF locally?

Supported browser operations can use Zero-Upload Client Privacy Mode. The standalone Tauri client is designed to run compression entirely on the device.
