# Clean it on your device before you share it

> StartPrivate removes hidden details that files carry (GPS coordinates, camera serial numbers, document authors, tracked changes) and covers what is visible (faces, plates, card numbers) before you send anything. Every tool runs in your browser tab, so the files you choose are not uploaded; heavier helpers such as the face finder download from this site only when you press their button.

## How it works

Pick a tool below, choose your files, and save the cleaned copies. The work happens in the page itself: photos are cleaned byte by byte without being re-encoded, videos are cleaned in place without touching picture or sound, Office files are rewritten without their author and comment data, and redaction draws a fresh image with your covers burned in. Nothing you open is sent to this site, which serves static files only. If you want to confirm that rather than take it on trust, [the methodology page](/methodology/) shows how to watch your browser's network activity while a tool runs.

## Redact photos and screenshots

Cover what is visible in a picture. The solid block is the default; pixelate and blur are marked as decorative because they can sometimes be reversed.

- [Redact a screenshot](/redact-screenshot/): finds email addresses, phone and card numbers and QR codes in a screenshot so you can black them out.
- [Redact an image](/redact-image/): flatten solid covers over IDs, bills, labels and boarding passes.
- [Censor a photo](/censor-photo/): hide house numbers, screens, mail or tattoos before posting.

## Passwords

Generated in your browser from the operating system's secure random source; nothing is saved or sent.

- [Passphrase generator](/passphrase-generator/): random words from the EFF list, six by default.
- [Diceware](/diceware/): the same list with the five dice rolls for each word, so you can roll your own.
- [Password generator](/password-generator/): random passwords from 4 to 128 characters with the character sets you choose.

By length: [8](/password-generator/8-character/), [10](/password-generator/10-character/), [12](/password-generator/12-character/), [14](/password-generator/14-character/), [15](/password-generator/15-character/), [16](/password-generator/16-character/), [20](/password-generator/20-character/), [24](/password-generator/24-character/), [32](/password-generator/32-character/) and [64](/password-generator/64-character/) characters, each page with its own entropy and cracking-time figures and where that length fits.

By rule:

- [Memorable](/password-generator/memorable/): three capitalized words and two digits, joined by hyphens.
- [Wi-Fi](/password-generator/wifi/): 20 characters with no look-alike letters, easy to type on a TV remote.
- [PIN](/password-generator/pin/): six uniformly random digits by default.
- [No symbols](/password-generator/no-symbols/): letters and digits only, for sites that reject symbols.
- [Pronounceable](/password-generator/pronounceable/): consonant-vowel syllables you can say out loud.
- [Easy to type](/password-generator/easy-to-type/): lowercase letters and digits in groups of four.

- [Encrypt text](/encrypt-text/): lock a note with a password or pack it into a link after the #.
- [Password strength checker](/password-strength-checker/): a 0 to 4 score on your device, with an optional breach check that is off until you tick it.

There are no accounts and no file storage on any server, and nothing you process is sent anywhere. The site cannot recover a file or a password for you, and it does not offer links that host your files.
