Blur / Redact

Blur or hide parts of a photo

Sometimes a photo is fine to share except for one small part of it — a face in the background, a house number, a licence plate, an address on an envelope, or the exact dimensions written on a technical drawing. This tool lets you mark just those parts and hide them, while the rest of the picture stays perfectly sharp. Upload an image, box or brush over what should disappear, and save the result. It all runs in your browser, so the photo is never uploaded anywhere.

Crucially, the effect only touches the areas you mark. Everything else is the untouched original at full resolution — so you can hide the measurements on a plan without softening the plan itself.

Two ways to mark an area

Pick the tool that fits the shape you're hiding. The Box tool draws a clean rectangle — drag from one corner to the other over a line of text, a sign, or a number plate. You can draw as many boxes as you need. The Brushtool paints freehand: drag your finger or mouse over an irregular area, with an adjustable brush size for fine or broad coverage. Made a mistake? Undo removes the last mark, and Clear wipes them all, so there's no penalty for experimenting.

Blur vs. solid fill — which to use

There are two ways to hide the marked areas, and the difference matters when the information is sensitive. Blursoftens the area into an out-of-focus look — like glancing at a page without your glasses — and keeps the photo feeling natural, which is ideal for de-emphasising a background face or a bystander. You choose the strength with simple percentage buttons (10% up to 70%): if the text is still legible, tap a higher percentage until it isn't. The strength scales to the photo's resolution, so a high setting makes even fine print on a large image unreadable.

Solid fill — a black, white, or coloured block — is the safer choice for anything truly sensitive: exact dimensions, account numbers, a full address, a signature. A filled block removes the pixels entirely, so there is nothing left to recover. When in doubt, and especially for numbers and text you genuinely need gone, use fill rather than blur.

Common uses

People reach for this to protect privacy — hiding faces, kids, house numbers, plates, and addresses before posting a photo publicly — and to protect their own work. If you sell a design, a plan, or a made-to-order product, you might want to show the piece while hiding the precise measurements or construction details that make it easy to copy. Boxing out the dimension text on a drawing lets you share a convincing preview without giving away the specification.

A note for marketplace sellers

If you're editing a product photo for a marketplace, keep any hiding or marking to your secondaryimages (photos two through ten), not the main one. Etsy, for example, advises against watermarks and overlays on the main listing image — photos with them can be left out of Etsy's curated Finds and out of Google Shopping ads, which costs you visibility. Use a clean, honest photo of the actual item as the main image, and reserve blurring or redacting for the extra shots where you're protecting a detail.

Saved at full resolution

The result is exported at your photo's original pixel dimensions — the tool never shrinks it to a preview size — so the hidden areas are applied to the full-size image and the sharp parts stay sharp. Save as a JPG for a smaller file or a PNG for lossless quality. On a phone the Share button hands the finished image straight to Messages, Photos, or wherever you need it. If you then want to resize or shrink the file, the Image Resizer and Image Compressor handle that in your browser too, and the Crop to Frame tool trims a photo to a set size. Combining a few product shots into one image? Do that with the Collage Maker once the details are hidden.

Works on your phone

The whole thing is touch-first. Drawing a box or brushing over an area feels natural with a finger, and the page won't scroll out from under you while you draw. The tool switches, brush size, undo, and clear are all large enough to tap, and the marked areas show live on the image as you go.

Privacy: your photo never leaves your device

The image is loaded and edited entirely in your browser. Nothing is uploaded, nothing is stored on a server, and there is no account to create — which is exactly what you want when the whole point is to hide sensitive information. When you close the page the photo is gone, because it was never sent anywhere.

Frequently asked questions

How do I hide part of a photo?

Upload the image, then use the Box tool to drag a rectangle over an area, or the Brush tool to paint over an irregular shape. Choose Blur or a solid Fill, and only the marked areas are hidden — the rest of the photo stays sharp.

Is blur or fill more secure?

Solid fill is safer. A filled block removes the pixels completely, so nothing can be recovered. Blur is a soft, adjustable defocus — raise the strength percentage until the text is unreadable — but for truly sensitive details like numbers, addresses, or dimensions, use fill.

Are my photos uploaded to a server?

No. Everything runs in your browser — the photo never leaves your device, and nothing is stored or sent anywhere.
