by Hung Nguyen

Reduce the size of your PDF while maintaining its original quality and formatting offline. Free to download and use.

Everybody loves our online PDF compressor. It’s quick, it’s free, and it gets the job done - every time.

However, inevitably, there are instances where you may not have internet access or are not able to upload your files online. In such cases, you can switch over to the Smallpdf desktop app, readily available for installation and usage for your compression needs.

  1. First, download and install Smallpdf Desktop.

  2. Open the app, click ‘Compress PDF’.

  3. Drag your file into the toolbox, choose the output folder and click ‘Compress file’.

  4. Wait for the app to reduce the file size and you’re good to go.

How does the compression process work?

 

With Smallpdf, we take the file and scans it for repetitive data patterns. In turn, we replace this data with where unique identifiers - created by the software. With this method, we can significantly reduce the PDF size without affecting its quality, as the unique identifiers are much lighter in size. Doing so will allow you to cut down the amount of time spent on file uploads or cleaning out your storage.

Can I alter the compression rate?

 

Unfortunately not.

We aim to maximize our formula and reduce your file size as much as we can, without affecting the font, format, color and so forth, but there is no option to compress your files at the moment further. In case the tool does not reduce the file size to a level that is usable for your needs, you could always use an online service such as WeTransfer for file sharing; they take up to 2GB per file!

How to compress multiple PDFs offline

 

Batch processing is available with Smallpdf Desktop.

To compress PDF files all in one go, repeat the previous step, by drag and drop multiple PDFs into the toolbox all at once, before clicking ‘Compress X files’. There is no limit to how many files you can process simultaneously, either!

The desktop app is free?

 

Unlike its online sibling, the desktop app will activate a 100% free trial as soon as you have it installed for a few days.

On the contrary, the online version of the compress tool allows you to compress PDFs twice every hour. All offline functionalities are available for you to view and modify your documents. There are tools to split, merge, as well as to convert files to and from the beloved PDF format.

Is my OS compatible?

 

The offline app works on Windows 7+ or MacOS 10.9+.

If you are not currently running on one of these operating systems, you can always return to compressing your PDF files via our online site. It offers the same tools, with a slightly different UI and the same processing power. The online version will also allow you to export PDFs from Google Drive or Dropbox to work with on our platform.

Where do I get started?

 

Head over to the download page to get started. It should not take more than a few minutes to get app running, for you to compress PDF offline.

If you wish to keep using Smallpdf for free after the trial period, you can switch to the online version. Otherwise, we offer you to go ‘Pro’ at the price of a coffee per week, which you can read more about via our signup page!
