The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about WhatFont.

  • Can only detect web-safe fonts and fonts loaded via web font services
  • Does not work on images with embedded text or rasterized typography
  • Limited to inspecting single text elements at a time
