Online PDF Compressor

Compress the size of your PDF for easier shareability without compromising quality in seconds.

There are dozens of reasons why you might compress your PDF files. You might want to free up space on your computer or reduce the amount of time it takes to upload or share a PDF with others. Whatever your reason, we’ve got you covered. However, the big trade-off on file compression is that the more you reduce the size of a file, the more quality is sacrificed. While this may not be a huge issue for some, a PDF comprised solely of text may become unreadable after compression. Fortunately, our PDF compression tool compresses your file to the optimal amount while also maintaining the highest possible quality.

  3. After the process has completed, download and save your new, compressed PDF to your computer.
  4. After your files have successfully compressed, all remaining files will be deleted from our servers automatically.
