Everything you need to know about privacy, case styles, Unicode generators, and how Case Modify processes your data locally.
Tool basics
Case Modify includes case converters, text cleanup tools, code formatters, encoders, random generators, and unit converters. Each page focuses on one task and includes examples or guidance for that workflow.
Privacy basics
Standard text conversion and formatting happen in your browser. You can paste text, convert it, copy the result, and leave without creating an account.
Mobile usage
The tools are designed to work on modern mobile browsers. Larger code-formatting tasks are easier on desktop, but basic text conversion works well on phones.
Frequently asked questions
Is Case Modify free to use?
Yes. Every tool is free: no account, subscription, or usage cap. Convert case, format JSON, generate passwords, and convert images without signing up. We support the site with unobtrusive ads and optional Ko-fi tips.
Does Case Modify store my text?
No. Almost every tool processes input in JavaScript in your browser. We do not upload your paste for conversion. The homepage editor and notepad may save a draft in this browser’s local storage on this device only.
What is the difference between sentence case and title case?
Sentence case capitalizes the first letter of each sentence (The quick brown fox). Title case capitalizes major words in a heading (The Quick Brown Fox) and usually leaves short words like and, the, and of lowercase in the middle. Use sentence case for emails and paragraphs; title case for headlines — unless your language’s house style says otherwise.
Can I use Unicode bold or italic on social media?
Usually. Those generators emit Mathematical Alphanumeric characters, not a font file. Instagram, Discord, TikTok, and WhatsApp often display them as bold or italic. Always preview on the phone that matters; missing glyphs become boxes. Prefer real markdown in Discord chat when the channel parses it.
How do I fix text typed with Caps Lock on?
If the whole paragraph is uppercase, use sentence case or lower case on the homepage converter. If the first letters are inverted (hELLO wORLD), run Inverse Case first, then sentence case for prose.
What is camelCase used for?
camelCase is the usual style for JavaScript/TypeScript variables and many JSON keys: userProfile, isActive. Convert spreadsheet headers or snake_case columns with the camelCase converter. Do not camelCase public URLs — use kebab-case slugs.
Do you have a mobile app?
Case Modify is a responsive website. Add it to your home screen from the browser menu for a PWA-style shortcut. There is no separate native store app yet.
How can I suggest a new tool?
Use Suggest a Tool and email what the input, output, and privacy model should be. We prefer utilities that can run entirely in the browser.
Why does Unicode bold look different on another phone?
You are not applying a typeface; you are pasting different Unicode code points. Each OS font may miss glyphs. Keep bios short and test the target app.
Can I use Case Modify offline?
After the page loads, most converters keep working without a network because the logic is client-side. The first visit still needs a download. A PWA install improves repeat access.
Are guides available in my language?
Yes. Navigation, the homepage case converter, FAQs, about/how-it-works/editorial pages, category hubs, and tool guides ship in English, Arabic, German, Spanish, French, Japanese, Malay, Portuguese, and Russian. Blog posts are translated when an editorial version exists for that language.
How do I support Case Modify?
Share a tool with a colleague, or use the Ko-fi link if you want to fund hosting. Accurate word-of-mouth beats fake reviews.
