Compress PDF to Size

Compress your PDF to reach an exact target file size. PDFSwap's intelligent algorithm automatically adjusts compression levels until your file meets your size requirement.

How to Compress PDF to a Specific Size

1. Upload your PDF – Select your file or drag it to upload
2. Set target size – Enter the maximum file size you want (in MB or KB)
3. Start compression – PDFSwap iteratively compresses until reaching your target
4. Download – Save your compressed PDF

Perfect For

How It Works

Unlike standard compressors that offer preset levels, PDFSwap's size-specific compression uses iterative algorithms to automatically find the optimal balance between quality and file size. You set the target size, and we handle the rest.

Privacy & Security

Your PDF is processed securely and deleted after 24 hours. We never store or access your documents.
