How to Use the File Name Generator

  1. Set a prefix, extension, and how many names you need.
  2. Choose separators and toggle date, sequence, or random suffixes.
  3. Click “Generate File Names” for unique results.
  4. Copy or download the batch.

Features

Customizable prefix, extension, separator (dash, underscore, or none), YYYYMMDD date stamps, zero-padded sequence numbers, random suffixes up to 16 characters, lowercase enforcement, automatic uniqueness with collision retry, and batches up to 500.

Benefits & Use Cases

Consistent naming makes files sortable, searchable, and script-friendly. Uniqueness guarantees prevent accidental overwrites during batch exports, uploads, and photo dumps.

Tips

Include the date for chronological sorting in any file manager. Dashes are the most URL-friendly separator. Keep extensions consistent with the actual file type to avoid confusion.

Frequently Asked Questions

Are the generated names guaranteed unique?

Yes, within each batch. The tool retries with a new random suffix if a collision occurs.

How many names can I generate?

Up to 500 per batch. Generate multiple batches for larger sets.

Can I generate names without an extension?

Yes. Leave the extension field empty and names are generated without one.

Why use lowercase?

Lowercase names avoid case-sensitivity issues when moving files between Windows, macOS, and Linux systems.
