Format CPF
Format Brazilian CPF numbers by adding or removing the 000.000.000-00 mask. Accepts a list with one CPF per line. Runs in your browser.
What is CPF formatting for?
Databases and systems usually keep CPFs as digits only, while documents and reports expect the 000.000.000-00 mask. This tool converts in both directions without touching data integrity.
Paste a list with one CPF per line and each line gets processed on its own. Any CPF with the wrong length is flagged.
Everything runs in your browser. Nothing goes to servers.

Format CPF in bulk
A CPF base almost always arrives mixed, some with dots and a dash, others as plain numbers. Here you can standardise it all at once: the 000.000.000-00 mask is applied or removed across an entire list of CPFs.
Paste several CPFs, one per line, and choose between adding the formatting (for display) or stripping it (to store only the numbers in the database). It's a simple trick that saves plenty of time when preparing data for import, export or display, leaving the whole base consistent.
Paste the list and copy the standardised version right away. The CPFs go nowhere, because the processing happens entirely inside the browser.
