How to compress PDF files
Use PDF Compressor to reduce a PDF's file size. It accepts a PDF, then lets you choose Screen, eBook, or Print, set custom DPI and quality values, or enter a target file size. You can preview the rebuilt PDF before downloading it.
Choose a PDF compression method
PDF Compressor has three preset choices and controls for custom settings. Pick the method that matches the output requirement:
- Choose Screen, eBook, or Print when a preset fits the job.
- Set custom DPI and quality values when you need to choose those settings directly.
- Enter a target file size when the rebuilt PDF needs to fit a stated size requirement.
- Preview the rebuilt PDF, then download it.
Use a target file size
Enter a target file size when the rebuilt PDF needs to meet a stated size requirement. If you want to choose the output settings yourself, use custom DPI and quality values instead.
PDF Compressor names its presets Screen, eBook, and Print. Their individual DPI and quality values are not stated here. Set custom values when you need to choose them directly.
