What is PDF compression?
PDF compression is when you reduce the size of a PDF file. It works by removing non-essential items such as embedded fonts, metadata, or images. Then it optimises your files for efficiency and safety—all without impacting your file’s readability.
You can usually use a PDF Compressor to resize your PDFs. This can make it easier to upload and share your files without the big data requirements, as compressed PDFs take up less space.
Sound complicated? Trust us, it isn’t. Just drag and drop your PDF into Adobe’s free compression tool to get started.

How to compress a PDF online
Adobe Acrobat is the fastest PDF compression software. Best of all, it’s free and easy to use online. Simply upload your file, choose a compression level, and then download a compressed, resized PDF. Just follow these simple steps:
- Click on the blue “Select a file” button to bring up your file browser and select the PDF file you want to compress. Then click “Open”. Alternatively, you can drag and drop your PDF file into the dotted drop zone to speed up the selection process.
- When you compress a PDF, it’s not one-size-fits-all. Select your compression level from either “High”, “Medium” or “Low” to suit your needs. The higher the compression, the greater the reduction in file size, but it will take longer. Additionally, images and videos could lose some quality.
- Once you’ve made your decision, click “Compress”. Our compressor tool will automatically reduce the PDF file to the desired size.
- Before you close your browser, you’ll probably want to save and download your newly compressed PDF. From here, you can store your new, smaller file on your PC, or you could sign in and share it with collaborators right from the Adobe site.
