Compress PDF
Shrink a PDF by re-rendering its pages at lower quality. Note: pages become images (text won't stay selectable).
Reduce a PDF's file size so it's easier to email or upload, right in your browser. Your document is never sent to a server.
How to use Compress PDF
- Add your PDF.

Frequently asked questions
How does the compression work?
It re-renders and re-encodes the pages to cut file size. Image-heavy PDFs shrink the most; text-only PDFs are already compact.
Will the text still be readable?
Yes. Pages stay legible; the savings come mainly from optimizing embedded images.
Is my PDF uploaded?
No. Compression runs locally in your browser, so your document never leaves your device.
