FAQ
Why can't I select text after compressing?
This tool rasterizes and re-encodes pages, so text becomes an image. If you need selectable text, don't compress.
Which PDFs compress best?
Scans and image-heavy PDFs shrink the most; text/vector-only PDFs may barely shrink or even grow.
Are my files really not uploaded?
Yes. This tool processes files locally in your browser using built-in capabilities; file contents are never sent to any server. Verify in the DevTools Network panel — no upload request appears during processing.
Is it free? Any signup or limits?
Completely free, unlimited, no signup required. File size is limited only by device memory; process very large files on a computer.
