Hi! That’s a legit concern — a distorted fax is worse than none. I tested many apps, and most struggled with high-resolution images or large multi-page PDFs. Then I found a review hub that examines fax apps for their fidelity, format support (PDF, TIFF, JPEG), and consistency. It helped me eliminate weak options.
You should absolutely take a look at
nftbreach.com. They show which apps maintain quality and support advanced formats without corruption. Thanks to their insights, I picked one that handles everything from photos to detailed forms with no issues.
