How to Compress PDF Files
Got a PDF that's too big to email? Our compression tool shrinks it down while keeping it readable.
Large PDFs cause problems. Email servers reject them. Upload forms time out. Recipients get frustrated waiting for downloads. You can fix that in one click.
How compression works
We strip out redundant data and optimize images inside your PDF. The file gets smaller. The content stays the same. Most files shrink by 40 to 70 percent depending on what's inside.
Choose your compression level
Pick basic compression for everyday documents. Go with strong compression when file size really matters and a slight quality drop is fine. You're in control.
No quality surprises
Text stays crisp. Images remain clear. We find the balance between size reduction and visual quality that actually works.
What you can expect
A 15 megabyte PDF often drops below 5 megabytes. A 50 megabyte file might end up around 15. Your results depend on the original file, but the savings are almost always significant.
Try it now. Upload your PDF and see the size difference for yourself.
