Why use a filename sanitizer?
When you handle documents, screenshots, thumbnails, and attachments, messy file names often become a small but constant source of friction. In shared folders, blog uploads, and submission packages, consistent naming rules make files easier to sort, search, and reuse.
This tool helps you:
- normalize spaces and special characters
- unify separator style
- add a date prefix and sequence numbers
- copy a cleaner output list for the next step
How to use it
- Paste titles or file names, one per line.
- Choose hyphen, underscore, or no separator.
- Optionally force English letters to lower/upper case.
- Turn on date prefix and numbering if needed.
- Copy the cleaned list and use it in your folder or upload workflow.
Especially useful for
1) Blog or CMS asset uploads
Clean image names before uploading thumbnails and post assets.
2) Assignment and submission files
Keep report, version, and submission-date naming rules more consistent.
3) Shared team folders
Reduce naming chaos before a folder grows too large to manage comfortably.

FAQ
Does it add extensions automatically?
If an extension like .png or .pdf is already present, the tool keeps it. If there is no extension, it only cleans the name itself.
Can I use my own date instead of today?
Yes. You can leave the date off, use today, or choose a custom date to prepend.
Do I have to remove all special characters?
Not always, but replacing risky punctuation with safer separators usually reduces upload and compatibility problems.
Summary
The Filename Sanitizer is a utility-type tool that turns inconsistent titles or messy file names into cleaner, rule-based names you can copy right away.
