DocomintKeep Only Numbers
Extract only the digits from a block of text — useful for pulling phone numbers or IDs out of messy input.
Strips a phone number, ID, or price down to just its digits — paste in "(555) 123-4567" and get "5551234567" back, ready to paste into a field that expects digits only.
Example: "Invoice #INV-2026-0341, due $1,250.00" becomes "20260341125000" with spaces off.
How it works
- Paste text containing digits mixed with other characters
- Everything except digits is removed instantly, on your device
- Copy the digits-only result
Frequently asked questions
Why would I need to keep only numbers?
Common uses include pulling a phone number, ID, or account number out of text that has labels or formatting mixed in, before pasting it into a field that only accepts digits.
Is my text uploaded anywhere?
No — Keep Only Numbers runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
Does this keep decimal points and minus signs, or strip those too?
Only digits 0-9 are kept — decimal points, minus signs, and commas are stripped along with letters and other symbols, so a price like $1,250.00 loses its decimal point too.
