Why Compress PDFs Before Emailing?
Email servers typically limit attachments to 10-25MB. Large PDFs containing high-resolution images or many pages can easily exceed these limits. Compressing PDFs before emailing ensures your documents arrive without bounce-backs or failed uploads.
Beyond email limits, smaller files download faster on mobile connections and use less storage space in email archives and inboxes.
