Case Modify

About Case Modify

Case Modify is a free online text toolkit: case converters (uppercase, lowercase, title case, sentence case), Unicode stylers, code formatters, encoders, random generators, and unit converters. Every tool runs in your browser - no account required.

Purpose-built toolsEach page focuses on a specific conversion, formatting, or reference task.
Privacy-first workflowsStandard text tools process input in the browser after the page loads.
Accessible by defaultPages use semantic headings, visible links, keyboard focus states, and mobile layouts.

Who uses Case Modify

Students fix essay capitalization, bloggers format headlines, developers prettify JSON and test regex, marketers build UTM links, and teams share quick utilities without installing desktop software.

Privacy-first by design

For standard tools, your text and values stay on your device after the page loads. That makes Case Modify practical for drafts, proprietary snippets, and customer data samples you do not want uploaded to a remote formatter.

Editorial standards

Guides and examples are written to be practical, plain-language references. We review pages for clear intent, examples, internal links, and corrections when a tool behavior or style recommendation changes.

Case Modifyは独立したテキスト・コード・画像・乱数ツールのサイトです。必須アカウントはありません。貼り付け、このタブのJavaScriptが計算し、コピーします。広告ネットワークも検索も、同じ3文の量産を求めません。案内は自分で書いています。

Overview

誰が書き、なぜブラウザで変換し、ドアウェイページを避けるか。

編集

変換処理を実装し、用途・向かない場面・近隣ツールを書きます。他サイトのFAQは引き写しません。InstagramやWhatsAppのページは、それらの制約を述べます。

ブラウザで処理する理由

大文字小文字の入れ替えに遠隔GPUは不要です。下書きやトークン、身分証写真を送りません。初回読み込み後はオフラインでも使えるものが多くあります。

何ではないか

文法チェッカーでもウイルス対策でも公的抽選でもありません。MD5やシーザーは実際の強度どおりに書いています。装飾Unicodeはプロの組版ではありません。
