Write notes directly in the browser with automatic saving!

Notepad is a practical tool for writing simple text notes and automatically saving them in the browser. You can start writing immediately without separate installation or login, and content persists even after closing the browser using the browser's local storage technology.

Real-time statistics including character count, word count, line count, and byte size make it useful when writing text for places with character limits.

Quick idea notes, to-do lists, code snippet storage, text organization, and more - a lightweight and convenient notepad tool for various uses.

  1. 1

    Enter text

    Type in the text area. Changes auto-save immediately.

  2. 2

    Verify auto-save

    A 'Saved' indicator appears as you type — no manual save needed.

  3. 3

    Test refresh

    Refresh the browser to confirm notes persist.

Example — Meeting notes

Jot meeting notes quickly, then copy-paste to your internal doc system after the meeting. Notes persist after closing the browser, so you can review them later.

Auto-Save Feature

localStorage.setItem('key', content)

Uses the Web Storage API's localStorage to permanently store data in the browser. Auto-saves after 1 second of no input, and content persists even after closing the browser.

Statistics Calculation

Character count is calculated using content.length, word count uses whitespace-based split, and byte size uses the Blob object for accurate UTF-8 byte measurement.

Notepad Usage Tips

  • Quick notes: Useful for quickly recording ideas or to-dos during meetings or on the go.
  • Text organization: Use it for drafting long documents or organizing online text.
  • Code snippets: Temporarily store frequently used code or commands for instant copy when needed.
  • Copy-paste hub: Convenient for managing multiple texts in one place and copying them where needed.
  • Character limit check: Verify character count before writing text for SNS, applications, and more.
  • Caution: Do not store important passwords or personal information in the browser.

QIs notepad data saved outside the browser?

No. All data is stored in browser localStorage only — never sent to a server. Accessible only on the same browser/device; clearing browser data deletes the notes.

QHow often is auto-save triggered?

Auto-saves on every keystroke — no manual save needed. If the browser crashes, some content after the last auto-save may be lost.

QDoes it sync across devices?

No sync. Each browser's localStorage is isolated. To view PC notes on mobile, copy-paste or export. Use dedicated note apps (Notion, Obsidian) for cloud sync.

QCan I export notes to a file?

This version may not have auto-export. Select all text, copy with Ctrl+C, and paste into a .txt file. Manual backup is recommended for important notes.

QIs there a localStorage size limit?

Most browsers allow ~5–10 MB per domain for localStorage. Normal notes won't hit this, but very long text may. Exceeding the limit truncates the earliest data.
