How CaseSwitch works
Local processing, the homepage case converter, and when to open a dedicated tool — explained without marketing fog.
CaseSwitch is a static website plus client-side JavaScript. Your paste is not a job we queue on a GPU farm. Understanding that model helps you choose the homepage converter versus a dedicated page, and to know what still needs a network.
1
Choose the homepage converter or a dedicated tool
Stay on the homepage for a quick case switch. Search the header or open a category if you need encoding, images, or Unicode styles.
2
Paste or drop a file
Text tools take a paste. Image and document tools take a file the browser can read. Drafts on the homepage can stay in local storage on this device.
3
Adjust options when they matter
Title-case small-word lists, JPEG quality, password length, regex flags — defaults are for one-off tasks; options are for control.
4
Get a result in the browser
Output updates as you type for most text tools. Nothing in that loop is a server conversion.
5
Copy, download, or share
Use the action bar. Undo/redo exists on text editors. Clear the field on a shared computer.
Homepage versus dedicated tools
The homepage converter is the fastest path for everyday case changes: sentence, title, upper, lower, capitalized, camelCase, and the other styles on the switcher. Open a dedicated URL when you need extra options (find and replace, JPEG quality, JSON pretty vs minify) or the longer guide that belongs with that transform.
What still needs the internet
The first load of each page, ads if they are enabled, and analytics if you have not blocked them. Conversion logic for text, most encodings, and canvas image work does not require a round trip after that load.
Limits we will not hide
Title case is a web default, not APA or Chicago in full. Unicode fonts are not installable typefaces. MD5 is a checksum, not password storage. PDF extraction needs a text layer. We would rather lose a keyword than over-claim.
