Generate strong passwords

This is a brand-new password tool. It generates passwords locally with the browser crypto API and does not save them. Keep copied passwords in a password manager rather than a note or screenshot.

Base64 Encoder / Decoder Encode text or files to Base64 and decode Base64 back to readable text or downloadable files in a browser-first workflow that stays on your device.

Diff Checker Compare two text blocks side by side with inline change highlights when you need to review edits, pasted drafts, code snippets, or document revisions.

What to Expect

Generate one or many stronger passwords locally in the browser with adjustable length, character sets, and a visible strength estimate before you copy the final result.

Best for

  • Quick browser-side jobs that solve one practical problem cleanly.
  • Repeat-use utilities such as packaging files, comparing text, or converting values.
  • Workflows where privacy-first local processing improves trust and convenience.

Not ideal for

  • Very large source files or very long batches on older low-memory devices.
  • Heavy desktop-grade editing workflows that need multi-step controls or plugins.
  • Scenarios where you need server-side storage, sync, or background processing.

What this tool keeps

  • A focused single-task interface with clear limits and copy-ready output.
  • The convenience of handling the job directly in the browser where supported.
  • Fast access to practical utilities without signups or forced app installs.

What may need cleanup

  • Browser performance can vary by device, especially on large local files.
  • Some outputs still need a quick human check before you rely on them.
  • Browser feature support can affect folder upload, timezone data, or clipboard access.

Common errors

  • Pasting invalid text or encoded data and expecting the tool to guess the right format.
  • Assuming every file type compresses well inside a ZIP archive.
  • Using the wrong time zone name or measurement category for the task.

Example use cases

  • Create fresh login passwords for work tools, stores, admin accounts, and client platforms.
  • Generate several alternatives when a website blocks specific symbols.
  • Use the strength meter as a quick sanity check before saving the password in a manager.

Sample input

A target length plus the character sets you want to include or exclude.

Sample output

One or more random passwords with a strength estimate based on the current settings.

Who this is for

  • Anyone creating new account credentials who wants a fast privacy-first generator.

Frequently Asked Questions

Are generated passwords created locally?

Yes. Passwords are generated in your browser using the Web Crypto API and are not sent to Tiny File Tools servers.

Can I generate more than one password at a time?

Yes. You can create a batch of passwords in one run if you need options for multiple accounts or devices.

What does the strength meter mean?

It gives a practical estimate based on length and character variety. It is helpful for comparison, but your password manager's policy may still differ.

Can I exclude similar-looking characters?

Yes. You can remove confusing characters such as O, 0, I, and l if you need passwords that are easier to read aloud or type manually.
