Free File Name Generator
Naming hundreds of files by hand is soul-crushing — NToolHub’s File Name Generator does it in one click. Build batches of unique, clean file names from a prefix, date stamp, sequence number, and random suffix, with your choice of separator and extension. Photographers, developers, and data teams get consistent, collision-free names every time.
How to Use the File Name Generator
- Set a prefix, extension, and how many names you need.
- Choose separators and toggle date, sequence, or random suffixes.
- Click “Generate File Names” for unique results.
- 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.
