PDF Compressor

What is PDF Compressor?

Compress PDF files to reduce their size without losing quality. The tool shrinks embedded images, removes redundant data, and cleans up the PDF structure. Processing happens entirely on your device — your documents never leave it.

How to use

1. Upload the PDF file you want to compress. The tool displays the original file size and page count.
2. Select a compression level: low (best quality), medium (balanced), or high (smallest size). Each shows an estimated output size.
3. Click 'Compress' and download the optimized PDF. Compare the before and after file sizes to see your savings.

Result
