Is my image uploaded?

No. Everything happens on this page. Load it, disconnect from the network, and it still works, which for this tool in particular is the only promise worth making.

Is a blur actually safe for hiding a face or a number?

Not always, and this is worth knowing. Blur and pixelate both scramble the original rather than removing it, and a weak setting on either can sometimes be partly walked back, especially on text and on a face that appears elsewhere unblurred. For anything that genuinely matters use the black box: it replaces the pixels instead of rearranging them, and there is nothing left to recover.

Does it strip the location data too?

Yes, as a side effect. The result is drawn fresh rather than edited, so the EXIF block, including any GPS coordinates, does not survive into the file you download.

Can it blur the background behind a person?

No. That needs the subject found first, which is a different job and a different page here. This blurs where you tell it to.

This is the tool where the question of where it runs stops being a detail. People blur a picture to hide something: a face, a home address, a card number, the name on a letter. Every other free blur tool online takes that picture onto a server first. Hiding a thing by first sending it to a stranger is the joke at the centre of this whole category, and it is the reason this page does the work in your own browser instead.

1
Drop an image in
PNG, JPEG or WebP, up to 25 MB, read from disk and never uploaded.
2
Drag a box over what to hide
One box or several, over a face, a plate, an address. Move them, pull their corners to resize, press Delete to drop one. Draw nothing and the whole picture is treated instead, which is the plain soft focus job.
3
Blur, pixelate or black it out
The picture on screen is the file, redrawn as you adjust. Download when it looks right.
