Keep only numbers

Remove every character that is not a digit (0–9) from any text instantly and effortlessly. Paste a phone number, an address, a date, a product code, an identification number, or any text with mixed characters and this tool extracts just the numbers in seconds. Everything runs locally in your browser, so your data never leaves your device. No uploads, no tracking, no servers involved.

The tool strips away letters, punctuation, symbols, emoji, accents, and whitespace in a single pass, leaving only the numeric digits zero through nine. This is essential when you need to extract phone numbers from contact info, find numerical sequences in longer text, clean up formatting inconsistencies, or prepare raw data for spreadsheets and databases. By default it collapses the output to a continuous string of digits with no spaces. However, you can enable the "Keep spaces" option to preserve spaces between number sequences, which is helpful if you are processing formatted data like international phone numbers with country codes, postal codes with hyphens, or date formats with slashes.

Copy the result with one click, download it as a plain text file, or seamlessly send it to another tool using TextArray's integrated linking. The live tally displays statistics counting how many characters were in the input and output, plus the total number of characters removed.

FAQ

How does the tool work?
It scans your text character by character and keeps only digits 0–9. Everything else (letters, punctuation, emoji, accents) is removed. The "Keep spaces" option preserves whitespace between number groups.
Can it extract phone numbers?
Yes. Paste a contact list or document with phone numbers mixed in, and it will extract just the digit sequences. Enable "Keep spaces" to preserve formatting like country codes and area codes.
What happens to special characters?
All non-digit characters are removed — letters, punctuation, emoji, diacritics, symbols. Only digits 0–9 remain in the output.
Is my text uploaded anywhere?
No. The tool runs entirely in your browser and your text never leaves your device.
