IconVault's Numeronym Generator turns long words into i18n-style numeronyms: the first letter, the count of letters in the middle, and the last letter. So internationalization becomes i18n, localization becomes l10n, accessibility becomes a11y and Kubernetes becomes k8s. Paste a whole list and every word converts at once, with a one-click copy of the results.

It runs fully in your browser, is free with no signup, and works on bulk lists. Words of three letters or fewer are left unchanged since a numeronym would not shorten them. The honest note: generated forms follow the standard pattern mechanically, so for a public project name still check that the result is not already taken and reads the way you intend.
