Compress a PDF
Reduce the size of your PDF files without losing readability. Three levels: light for on-screen viewing, balanced for everyday use, print to keep high resolution. Compression mainly acts on images, which account for almost all of a PDF's weight.
If the file can't be reduced, the original is returned unchanged: no risk of degrading an already optimized document.
How it works
- Drop your PDFs (up to 20)
- Choose the compression level
- Download the lighter files
Frequently asked questions
How much can I save?
On a scan or an image-heavy document, often 50 to 90%. On a text-only PDF, little or nothing.
Does the text stay sharp?
Yes, vector text is untouched. Only images are recompressed.
Which level for email?
Balanced. It gets under most mailbox limits while staying readable.
