Frequently asked questions

How much smaller will my PDF get?

Scanned and image-heavy PDFs shrink the most — often by 50–90%. A text-only PDF is already small and may not shrink much.

Why is the text not selectable after compression?

This tool compresses by re-rendering pages as images, which is what makes big size savings possible — but it means the text is no longer selectable or searchable.

Is my PDF uploaded to be compressed?

No — compression runs entirely in your browser, so the file never leaves your device.
