About Compress PDF

Compress PDF reduces the file size of your PDF so it is easier to email and upload. Choose from four levels: Lossless keeps every pixel, Recommended shrinks large images while text stays sharp and selectable, and Strong and Maximum make the file smaller still. Paperwing shows the size before and after, and keeps your original if it can't make the file smaller.

  • No queues, no waiting There is no upload step, so a 50-page merge finishes about as fast as your device can read the files.
  • Chain your tools Finished merging? Send the result straight to Compress, Sign or Page numbers without downloading in between.

Frequently asked questions

Is Compress PDF free?

Yes. Compress PDF is free to use, with no sign-up, no watermark and no daily limit.

Are my files uploaded to a server?

No. Paperwing processes your files inside your browser, on your own device. They are never uploaded, and they are cleared from memory when you close the tab.

Does it work on my phone?

Yes. Paperwing works in any modern browser on Windows, Mac, Linux, Android and iPhone, with nothing to install.

Is there a file size limit?

Each file can be up to 300 MB. Very large files depend on your device's memory, so a computer handles them faster than a phone.
