PDF conversion guides

If you’ve ever dealt with trying to send a large file via email, you know how frustrating it can be. Many email servers flat out refuse to accept email attachments of a certain size. To help save you time and hassle, try compressing your PDF file before you send it.

How to compress PDF for emailing?

Some PDFs need to be compressed to fit into email service providers' file size limits. We recommend shrinking file size using custom compression settings and removing all unnecessary assets. However, if that still doesn't help, you can use our PDF split tool and send PDF in separate emails.

How to compress PDF on MAC or PC?

With our Compress tool, you can make your files smaller either on Mac or PC - it works online on all modern browsers like Chrome, Firefox, Edge, or Firefox. It means you don't need to have anything installed on your Windows or Apple computer. You can compress PDF on iOS or Android devices as well.

How to compress PDF without losing quality?

There are always some sacrifices when compressing files. You can remove metadata, reduce image quality, or remove assets like fonts. Even though sometimes you want to keep the document as close as possible to the original version. In this case, we recommend using custom compression options and removing metadata only. You can also set up image quality to 80-90% - this should make the file size smaller, but images would still look very sharp.
