What Ibra Font Lab checks

Kerning

80 letter pairs that usually need adjusting, like AV, To, Ty, Wa and r. — measured with your browser’s own text engine, the same one your customers’ browsers use.

Spacing

The white space between straight and round letters (HH, HO, OO and nn, no, oo). Even spacing is what makes a word look calm.

Characters & languages

Basic letters, numbers and punctuation, plus 13 languages from Indonesian and Spanish to Polish and Vietnamese.

Windows clipping & file info

Whether swashes get cut off in Windows apps, embedding permissions that block PDFs, missing names and license info.

Privacy: your font is read by your own browser and is never uploaded to our server.
