Screenshots and photos often contain more than you meant to share: an account number in a payment confirmation, a customer's email in a support ticket, a colleague's name in a chat, a home address on a parcel, a child's face in the background. Redacting means covering that information so it cannot be read, and doing it in a way that cannot be undone.
This tool redacts images with solid blocks in any colour, or with blur and pixelation for a softer look. Draw rectangles, circles or freehand shapes over anything sensitive, then download a flattened copy where the original pixels are gone. It runs entirely in your browser, so the unredacted original is never uploaded.
Before
Screenshot of a bank transfer
Visible
Account number, name and reference readable by anyone.
After
Same screenshot, redacted
Blacked out
The original pixels under each box are replaced in the exported file.
The exported image is flattened, so the covered pixels no longer exist in the downloaded file. Keep the original private: it still contains everything.
Drop a screenshot, photo or scanned document into the workspace above. Selective mode, solid blackout and the rectangle tool are preselected.
Drag rectangles over text and numbers, use the circle for faces or the brush for irregular shapes. Pick a different colour if you prefer.
Use the comparison view and zoom in to make sure every detail is covered, including small print.
Export as PNG, JPG or WebP. Share the redacted copy, never the original.
| Style | Best for | Security | Look |
|---|---|---|---|
| Solid blackout | Numbers, names, addresses, text | Highest: pixels replaced | Black or coloured box |
| Pixelate | Faces, objects, backgrounds | Good with large blocks | Mosaic |
| Blur | Faces, casual privacy | Good at high strength | Soft and natural |
Blur and pixelation scramble pixels, but they keep a relationship with the original. Researchers have repeatedly shown that lightly blurred or coarsely pixelated text, especially numbers in known fonts, can be guessed by comparing it with candidates. A solid block has no such relationship: every covered pixel is replaced with the same colour.
Use solid blackout for anything that must stay secret, such as account, card and ID numbers, passwords, addresses and names. Blur and pixelation are fine for faces and backgrounds where you want the image to look less harsh, as long as the strength is high.
Many redaction mistakes happen in PDFs and word processors: a black rectangle is drawn on top of the text, but the text itself is still in the file and can be copied or revealed by deleting the box. An image works differently. When this tool exports, it flattens everything into a single layer of pixels. There is nothing underneath the block to recover.
If you need to share a redacted page from a PDF, convert the page to an image with the PDF to JPG converter, redact it here and share the image.
Screenshots capture far more than the part you were looking at. Before sharing, scan for:
Rectangles are fastest for lines of text and numbers. The circle tool suits faces and round logos, and the brush covers irregular areas like handwriting or a person in the background. The eraser removes any part you covered by mistake, and the comparison view lets you check the result against the original. In browsers that support the built-in face detection API, faces can be found automatically; everywhere else you cover them by hand.
Sending an unredacted screenshot to a website in order to redact it defeats the purpose. Here, the image is processed on your device with the browser canvas and never uploaded. After redacting, consider removing hidden metadata with the EXIF remover for photos taken with a phone.
When you share a photo of an ID card, passport or bill, it is often enough to show only part of the information. Many organisations ask for, or accept, documents with most digits of an ID number hidden. Before sending a full document, check whether a partially redacted copy would do.
Remember the parts that encode data even if they don't look like text: QR codes and barcodes can contain names, numbers and addresses, and the two lines of characters at the bottom of passports (the machine-readable zone) repeat the holder's details. Redact those as well, and add a note such as "Copy for verification only" with the Watermark Tool to discourage reuse.
Open the downloaded file and zoom in on every redacted area: covered text should be completely solid with no letter edges visible. Check that the file you are about to attach is the redacted copy, not the original, which still sits on your device. For phone photos, also remove location metadata with the EXIF remover.
Teams that share screenshots of customer data, for example in bug reports, training material or vendor tickets, should redact personal information by default. Solid blocks are the safest option because they leave nothing to reconstruct. Keep the unredacted original only where policy allows, and remember that redacting an image does not remove the information from the system it came from.
Share screenshots with customers' personal details blacked out.
Show that a transfer happened without revealing account numbers.
Redact names and identifiers in scanned pages before circulating them.
Post screenshots of conversations without exposing other people.
Add the image, keep the solid blackout style, drag rectangles over everything sensitive, and download. The exported file contains the black boxes instead of the original pixels.
Not from the downloaded file when you use solid blackout: the covered pixels are replaced before export. Blurred or lightly pixelated text can sometimes be guessed, which is why solid blocks are recommended for text and numbers.
No. Drawing a black box over text in a PDF editor often leaves the text underneath, where it can be copied. Here the image is flattened, so nothing remains under the box. To redact a PDF page, convert it with the PDF to JPG converter, redact the image, and share that.
Yes. Pick any colour for the solid blocks, for example white to blend with a document background.
In browsers that support the built-in face detection API, faces can be detected automatically. Elsewhere, cover faces by hand with the circle or rectangle tool.
No. Redaction happens in your browser; the original image never leaves your device.
Names, email addresses, phone numbers, account and card numbers, transaction IDs, addresses, faces, profile pictures and anything in browser tabs or notifications you didn't mean to capture.
Re-exporting writes a fresh image, but to be sure a photo carries no location or device data, run the result through the EXIF remover.
Yes. Use the eraser to remove part of a covered area before you export. After downloading, the redaction is permanent in that file.
PNG keeps screenshots and text crisp; JPG gives smaller files for photos. Both contain the solid blocks, not the original pixels.
