About the Compress PDF
Reduce the file size of a PDF so it is easier to email or upload. Choose how strongly to compress it.
How to use the Compress PDF
- Open your PDF.
- Choose a Compression Level: Low (High Quality), Medium (Recommended) or High (Min size).
- Start the compression and download the smaller file.
When to use the Compress PDF
- Making a PDF small enough to send by email.
- Meeting a size limit on an upload form.
- Saving storage space.
Common mistakes to avoid
- Compressing too far, which blurs images and small text.
- Compressing your only copy. Keep the original.
Tips
- Stronger compression lowers image quality and, depending on the method, text may not stay selectable. Check the result before sending it.
- Always keep a copy of the original file.
- PDFs that are mostly text are already small and will not shrink much.
Frequently asked questions
Which level should I choose?
Start with Medium. Use High only if you need the smallest possible file and can accept lower quality.
Why is my PDF so large?
Usually because of high-resolution images or embedded fonts.
