Improving Fax Quality: Blurry or Unreadable Faxes

Fax is a 1980s-resolution medium — roughly 200 DPI in black and white. Within that limit, preparation makes all the difference.

What SendFax.me does

Every paid fax transmits in HD (fine) quality, the highest standard fax resolution, at no extra cost. A one-page free welcome fax transmits at standard quality.

What you can do

• Start from a digital file, not a photo. A PDF exported from Word/Google Docs is pixel-perfect; a phone photo of a paper page starts degraded.
• If you must photograph a document, use Take a photo of a document on the New fax page from your phone: it converts the photo to high-contrast grayscale for you. Lay the page flat, in good light, and shoot straight on.
• Use 10pt+ fonts and avoid thin/light typefaces.
• High contrast: black on white. Gray text, highlighter marks, and colored backgrounds turn to mush at fax resolution.
• Avoid dense images. Logos are fine; detailed photos become halftone noise.

The receiving side matters too

An old machine with a worn drum, low toner, or dirty scan bar prints every fax badly — including yours. If a recipient reports poor quality on a document that previews sharp in your dashboard, their hardware is the usual suspect. The preview you see is exactly what was transmitted.
