Guides

What each kind of file quietly carries, why it matters, and what to do about it. No marketing in these — if we do not do something yet, the page says so.

You can do this today

• Photo privacy checkerCheck a photo for GPS coordinates, camera details, timestamps and faces before you post it. Runs in your browser — the photo is never uploaded.
• Remove metadata before sharing photosStrip GPS, camera and timestamp metadata from a photo before you share it. No upload, no account, and no re-compression — the picture keeps its original quality.
• Detect sensitive information in imagesFind GPS coordinates, faces, ID numbers, card numbers and boarding-pass barcodes in an image before you share it. Runs on your device — the image is never uploaded.
• Remove the author from a Word documentStrip the author, last-edited-by, company and comments from a .docx file, and accept tracked changes so deleted text stops travelling with it. Runs in your browser.
• Check a document before you upload it to ChatGPTSee what a file really carries before you paste it into an AI chatbot: author names, comments, edit history and hidden text. Checked on your device.
• File privacy scannerScan a file for personal data, hidden metadata, author names and edit history before you share it. Runs in your browser — nothing is uploaded, no account needed.
• Blur a face in a photoCover a face in a picture in two clicks. The blur is burned into the pixels and the photo is never uploaded — the whole thing happens in your browser.
• Auto-blur facesDrop a photo and every face is covered before you have looked at it. Uncover the ones you meant to keep. Runs in your browser; the photo is never uploaded.
• Blur the faces in the backgroundCover the people behind you without blurring the person the photo is of. One slider decides where the background starts. Runs on your device.
• Blur everyone in a photoCover every face in a picture, or every whole person, when a uniform or a build is as recognisable as a face. Runs in your browser.
• Blur the text in an imageFind the words in a photo or screenshot and cover them. Card numbers and addresses get a solid box, because blurred text can sometimes be read back.
• Blur part of an imageDrag a box over any part of a picture and cover it with a blur, a pixelation or a solid block. No account, no upload, no watermark unless you want one.
• Redact a screenshotFind the emails, tokens, card numbers and names in a screenshot and cover them with solid boxes. Runs in your browser; the screenshot is never uploaded.
• Blur a license plateFind the license plate in a photo and cover it with a solid box before you post. Works on your device, needs no account, and strips the GPS data with it.
• Hide a card number in a photoFind a payment card number in a photo or screenshot and cover it with a solid box. Checksum-validated, so order numbers are not flagged. Runs on your device.
• Blur an address in a photoCover a street address written in a picture, and remove the GPS coordinates the camera wrote into the file. Both happen on your device.
• Remove EXIF data from a photoStrip EXIF — GPS, camera model, timestamps — from JPG, PNG, WebP and HEIC in your browser. No upload, no re-compression, and the picture keeps its quality.
• Photo metadata viewerView everything a photo’s file carries — GPS coordinates, capture time, camera and software — without uploading it. Masked previews, and one-click removal.
• Remove location data from your photosTurn off photo geotagging on iPhone and Android, strip GPS from photos you already took, and check the result — all without uploading the picture anywhere.
• Remove tracked changes before you send a Word documentTracked changes keep the text you deleted and the name of everyone who edited. Accept them for real and clear the history — in your browser, no upload.
• What a photo reveals about youGPS coordinates, your daily routine, your home, your device, the people around you — what one posted photo can expose, with examples and what to do first.
• What a boarding pass photo gives awayThe barcode on a boarding pass carries your booking reference — enough to view or change a trip. Decode yours in your browser and see before you post it.
• Anonymize a photoCover faces and license plates, remove GPS and camera metadata, and download a copy with the identifying parts gone. Runs in your browser, no account.

Explained, but not switched on yet

• PII detection in images, with OCRFind PII in images — card numbers, IBANs, passport MRZ lines and national IDs, validated by checksum. OCR runs through the API today.
• Redact PDF metadata onlineWhat PDF metadata reveals, why drawing a black box over text does not redact it, and how to remove document properties, annotations and attachments properly.
• Hidden data in Excel filesHidden worksheets, hidden rows and columns, cell comments and revealing headings — what a spreadsheet carries beyond the cells you can see, and how to deal with it.

Compared with other tools

• Scrambled Exif alternativeScrambled Exif strips EXIF on Android through the share sheet. If you need the same on a desktop, or want what is visible in the picture caught too, here is how we compare.
• ExifTool alternativeExifTool is the most thorough metadata tool there is, and it is a command line. Here is how it compares with doing the same job in a browser, in plain English.
