Compress PDF
Reduce PDF size while keeping text, links, and original pages
How to use Compress PDF
Reduce PDF size by optimizing embedded images and PDF data while retaining selectable text, clickable links, bookmarks, forms, and metadata.
- Choose your PDF and a compression level, or set custom image quality and resolution.
- Compress the document and compare actual file sizes and the original and output previews.
- Download the smaller PDF. The original is retained if optimization would make it larger.
What to check before using the result
Image compression can reduce image detail. Text-heavy or already optimized PDFs may shrink only slightly. Transparent images and small graphics keep their original pixels. Digitally signed files are retained unchanged to protect their signature.
Common questions
Where does Compress PDF process my document?
This tool processes your document in your browser. There is no document upload to the application server for this operation. Download the result to keep your own copy.
Can I use Compress PDF on my phone?
Open Compress PDF in a modern mobile browser and use the same document controls. Large files and image-heavy documents can take longer on a phone; a desktop browser is useful when you need more screen space.
Is a CreatePDF account required?
No CreatePDF account is needed. Core PDF operations do not add a watermark. Download any output you need to retain.
