Frequently Asked Questions
How much can PDF compression reduce file size?
It depends on the content. Scanned documents and image-heavy PDFs typically shrink by 50-90%. The tool shows the exact before/after size, and keeps the original if compression would not help.
Is compressing a PDF online private?
Completely. Compression happens locally in your browser — the file is never uploaded, so it cannot be stored, read or leaked by any server.
Will compressed PDF text stay searchable?
The output is an image-based PDF: each page is re-encoded as an image for maximum size reduction. Text is no longer selectable. This is ideal for scans and image-heavy documents.
