How to use Compress PDF

  1. Choose your PDF file.
  2. Pick Recommended, Strong, Extreme or type a Custom size such as 200 KB.
  3. Tick Black and white if colour is not needed.
  4. Click Compress PDF and compare the old and new size.

Why use our Compress PDF

You can ask for an exact size. Many upload forms have a hard limit, and our target mode searches for the best quality that fits under it.

  • Exact target size in KB or MB.
  • Recommended and Strong keep text selectable.
  • Extreme rebuilds pages as images for the smallest file.
  • Black and white option for extra savings.
  • Clear before and after size, with the saving shown.

Tips for the best result

  • Start with Recommended. Move to Strong only if you need more.
  • Photos and scans shrink the most. Text-only PDFs are already small.
  • Keep your original file for printing.

Frequently Asked Questions

How much can a PDF be compressed?

Files with photos or scans often shrink by 50 to 90 percent. Text-only files are already small and shrink less.

Does it keep text selectable?

Recommended and Strong do. Extreme and some tight custom sizes rebuild pages as images, and the result page tells you when that happened.

What if my file cannot reach the size?

We get as close as possible and suggest options such as Black and white or removing pages with Split PDF.

Can I type my own size?

Yes. Choose Custom size and enter a value in KB or MB.

Is it free to use?

Yes. This tool is free, has no daily limit and does not ask you to sign up or install anything.

Are my files uploaded to a server?

No. The work is done inside your own browser, so your file stays on your device. We never see or store your documents.
