Blur a whole picture, or drag boxes over the parts you want hidden and blur, pixelate or cover each one. Nothing is uploaded.
🔒 Runs entirely in your browser — nothing you type is uploaded or stored on a server.
Drop a picture in and choose what to hide. Switch to Parts of the picture, drag a box over a face, a name tag, a number plate or an address, and pick blur, pixelate or a solid box for that area. Add as many areas as you like, each with its own effect; click one to select it, drag it to move it, drag its corners to resize it, or press Delete to remove it. Choose The whole picture instead to blur everything with a single strength slider.
Also on Txtset: flip or rotate it first · add caption text to it.
Blur and pixelation do not make a secret safe. Both keep a rough copy of what was underneath, and published attacks can recover text, numbers and sometimes faces from a blurred or lightly pixelated picture. For a number plate, a card number, an address or anything that must stay hidden, use the solid box: it replaces the pixels, so nothing is left to recover. If you do pixelate, make the blocks bigger than a single letter.
Nothing is uploaded. Your browser decodes the picture, applies the effects to a copy of its pixels and writes a new file. That file is built from the edited pixels alone, so it carries none of the original’s metadata — no GPS position, no camera details and no embedded preview thumbnail that could still show the unblurred picture. Download it as PNG, JPEG or WebP.
There is no automatic face detection, because browsers do not offer it reliably: you choose every area yourself. You also cannot blur only a background, which needs a cut-out of the person that this page does not make.
How to use
- Drop in, choose or paste a picture. A phone photo is turned the right way up automatically.
- Keep Parts of the picture, choose an effect, and drag a box over each area to hide. Use Solid box for anything that must stay secret.
- Adjust the area: drag to move it, drag a corner to resize it, use the arrow keys to nudge it (hold Shift for 10 pixels), or Delete to remove it.
- Choose a format and press Download the picture.
Examples
Hide a number plate
Drag a solid box over it. A blurred plate can sometimes still be read.
Soften a face in the background
Drag a box over it and use blur or pixelate. This is fine for looks, not for protecting someone.
Redact a name or address in a screenshot
Use solid box, then check the result at full size before sharing it.
Blur a whole photo
Choose “The whole picture” and set the strength, for a soft background image.
Frequently asked questions
Is blur or pixelation safe for hiding text, numbers or faces?
No. Blur and pixelation keep an averaged version of what was behind them, and published research has recovered text, digits and some faces from both. A strong blur or large blocks make that harder, but not impossible, so for anything that must stay hidden use the solid box. A solid box replaces the pixels entirely and the downloaded file holds nothing underneath it.
Does it find faces automatically?
No. Browsers do not offer reliable face detection, so you drag a box over each face yourself. The same goes for number plates and text.
Can I blur just the background and keep the person sharp?
Not here. That needs the person cut out of the picture, which takes an image-segmentation model this page does not use. You can drag boxes over the parts of the background you want to soften.
What does the blur strength mean?
It sets how wide the blur is, as a share of the picture’s longer side, so the same setting looks alike on a small image and on a large one. Under the hood it is a three-pass box blur, which comes out close to a Gaussian blur. An area is blurred using the real pixels around it, so its edges do not show a dark or bright fringe.
What does pixelate do, and how big should the blocks be?
It divides the area into squares and fills each with its average colour. Blocks smaller than a letter or a digit leave the shapes guessable, so make them clearly larger than the text you are hiding — or use a solid box.
Does the downloaded picture keep the original’s location and camera data?
No. The page draws your edited pixels onto a new image and saves that, so EXIF data, GPS position and any embedded preview thumbnail are left behind. That matters here: a photo’s thumbnail can show the unblurred picture even when the main image is blurred.
Which formats can I save?
PNG, JPEG and WebP, and AVIF where your browser can really write it (the page tests this rather than trusting the browser). “Same as the original” keeps the format when it can, otherwise PNG. JPEG cannot hold transparency, so a transparent picture is laid on white; PNG and WebP keep it.
Why does a very large picture say it was decoded at a smaller size?
To stay within what a browser can safely hold, pictures above about 16.7 million pixels (for example 4,096 × 4,096) are scaled down while they are read. The page tells you the size it used. For huge originals, resize first with the
Image Resizer.
Can I open an iPhone HEIC photo?
No browser reads HEIC on its own. Convert it first with the
HEIC to JPG converter, which also runs in your browser, and then bring the JPG here.
Can I use it without a mouse?
Yes. Click the picture or pick an area from the list, then use the arrow keys to move it (Shift for 10 pixels) and Delete to remove it. New areas are drawn by dragging, which needs a mouse, trackpad or finger.
Is anything uploaded?
No. The picture is decoded and edited by your own browser, and nothing is sent anywhere.
