How it works
Add files
Add a PDF.
Adjust the settings

Download the result
Download the compressed PDF.
Limitations
- Files up to 512 MB are supported; the actual limit also depends on the free memory of your device.
- Only images inside the document are recompressed: text, fonts and vector graphics don't change, so a text PDF barely shrinks.
- Images in CMYK, with a palette, black-and-white (1-bit), as well as JBIG2 and JPEG 2000 are not recompressed - a PDF made of such scans may barely shrink.
Frequently asked questions
Why did my PDF barely shrink?
Images and scans take most of the space in a PDF. A text-only document is already almost incompressible.
Will the text stay selectable?
Yes, only images inside the document are recompressed; text and vector graphics don't change.
