2. Open the “Optimise PDF” tool.
3. Locate your file and click Open.
4. Click Reduce File Size in the top menu.
5. Select appropriate compatibility settings and click OK.
6. Name your file and click Save.
   You can apply these settings to multiple PDFs using the dropdown menu: Reduce File Size > Reduce Multiple Files. Add all the PDFs you want to compress and then hit OK.

Why compress PDFs? The benefits.

Most email clients have size limits on attachments and your PDFs could bounce back if they haven’t been compressed. Reducing file size will ensure your documents are received on time.

You can optimise the storage on your own machine by compressing all the PDFs you have created. Remember to keep a backup if you want to keep your original, uncompressed PDFs.

Customise your compressed PDFs to ensure you maintain the exact quality you want.

Alternatives to compressing PDFs.

File transfer software enables you to send large PDFs that might bounce back if you try to email them. And you can also share PDFs by sending an anonymous or public link that makes the files accessible to anyone who clicks the link. The full-size is PDF is stored on the Adobe Document Cloud.
