01
Combine Your Documents Into One PDF
Fax systems work best when all pages are included in a single PDF.
Here are simple ways to combine pages:
• On Windows: Use the built-in Print-to-PDF tool or free PDF merge tools.
• On Mac: Use Preview → Thumbnail → Drag pages together → Export as PDF.
• On iPhone/Android: Use your phone’s document scanner and “Save as PDF.”
• Online PDF Mergers: Adobe, SmallPDF, and PDF.io all work well.
Make sure the order of your pages is correct before uploading.
02
Check Page Clarity Before Faxing
Multi-page faxes can fail if pages are too dark, too light, or poorly aligned.
Before sending, make sure:
• Text is dark and easy to read
• Photos or scans aren’t blurry
• Pages are upright (not sideways)
• Everything is combined into one clean PDF
Your final PDF should typically be under ~10–15 MB.
