Why should I compress a PDF for slow internet?

Large PDF files take longer to upload or download on slow internet connections. Compressing the file reduces transfer time and prevents upload failures.

How much can compression improve upload speed?

Reducing file size by 50–80% can significantly improve upload speed, especially on limited bandwidth or unstable connections.
