How does Czech capitalise titles differently from English?

English headline style capitalises most words. Czech follows sentence-style capitalisation: only the very first word and any proper nouns are capitalised, while ordinary nouns, adjectives, verbs, and conjunctions stay lowercase.

What counts as a proper noun in Czech?

Personal names, geographic names, names of institutions, brands, and similar fixed names are proper nouns and keep their capital letter wherever they appear. You can supply your own list so the tool preserves them.

Does the first letter always become a capital?

Yes. The first letter of the title is always capitalised, even if the first word would otherwise be lowercase, matching Czech sentence-initial capitalisation.

Will it break words that are already all caps, like acronyms?

Short all-uppercase tokens such as ČR, EU, or DPH are treated as acronyms and left unchanged so the tool does not damage abbreviations.

No. The transformation runs entirely in your browser, so your titles stay on your device.

Czech does not use English-style headline capitalisation. In a Czech title, only the first word and any proper nouns are capitalised; everything else — common nouns, adjectives, verbs, prepositions, and conjunctions — stays lowercase. This tool applies that rule, so Nový Průvodce Prahou becomes the correct Nový průvodce Prahou.

How it works

The tool processes a title in three steps:

Lowercase every word, except short all-uppercase acronyms such as ČR or EU, which are left untouched.
Capitalise the very first letter of the title (sentence-initial capital).
Re-capitalise any token you listed as a proper noun, matching case-insensitively, so names and places keep their capital.

Because Czech capitalisation is essentially sentence case plus proper nouns, this reliably produces a clean, correct title without over-capitalising.

Proper nouns

Supply names, places, institutions, and brands in the proper-noun box, separated by commas — for example Praha, Karlův most, Vltava. The tool keeps each of these capitalised wherever it appears in the title, so prague written as part of a name stays correct while ordinary words around it are lowercased.

Example

Input KOUZELNÝ SVĚT KARLOVA MOSTU with proper noun Karlův most becomes Kouzelný svět Karlova mostu after the first-word capital and proper-noun handling, matching standard Czech orthography.
