How to compress a PDF
Reduce the size of PDF files right in your browser by choosing a compression level.
- Upload your PDFs — drag and drop or pick one or several files.
- Choose the level — Light, Medium or Strong. The stronger the level, the smaller the file.
- Compress and download — see the before/after size and download the result.
How it works
Compression renders each page as an image and rebuilds the PDF. This greatly reduces the size of scanned and image-heavy PDFs. The trade-off is that text becomes non-selectable.
All in your browser
Compression happens on your device — nothing is uploaded to servers.
Other tools
- Merge PDF — combine several PDFs into one.
- Split PDF — separate or extract pages from a PDF.
