How to compress a PDF

Compressing a PDF online is simple: upload your PDF file, and Forma reduces its file size in seconds, ready to download or save to your cloud. Behind that one click, the compressor shrinks the file while keeping text readable and images as clear as possible, so your PDF stays usable instead of looking degraded. A smaller PDF is useful in plenty of situations - emailing a document that was too large to send, meeting an upload size limit on a form or portal, saving storage space, or making files load faster for the people you share them with. Because everything runs in your browser, there is nothing to install, and your files are processed over an encrypted connection and deleted automatically after compression, so compressing a PDF stays private and secure.
