How to compress a PDF

  1. Add your file. Select the PDF you want to make smaller.
  2. Choose a level. Pick “Recommended” for a good balance of size and quality, or “Maximum” for the smallest possible file.
  3. Compress and download. Select Compress PDF and download the reduced file.

Frequently asked questions

Will the text still be readable?
Yes. Compression mainly shrinks images; text stays crisp. On a text-only PDF the saving is small because there is little to compress.
Which level should I choose?
“Recommended” suits email and sharing. Use “Maximum” when size matters most, or “Light” to keep print-quality images.
Is this tool free?
Yes - it is completely free, with no account, no limits, and no watermarks added to your files. Every PDF tool on File-Extension works the same way.
