Blur / Pixelate Image

Not from the exported file. Blur and pixelation destroy the underlying pixels here, unlike drawing a black box in a PDF viewer that leaves the original data underneath. Keep the strength high: very light pixelation on short text has been reconstructed by researchers.

Yes. The export is a canvas re-encode, so EXIF including GPS is dropped along the way.

Only where the browser exposes a face detector; otherwise you select the regions yourself. Manual selection is more reliable, and it is what you want when the sensitive thing is an address rather than a face.

A strong Gaussian blur is generally the safer choice. A coarse mosaic preserves the average colour of each block, and for short, predictable content such as a plate or a postcode those averages have been matched back to an original before now. Whichever you pick, push the strength past the point where you can still guess the content.

Yes, and it is a safer route than most. The pixels underneath are genuinely replaced, whereas a black rectangle drawn in a PDF viewer or a word processor often leaves the original text sitting selectable beneath it.

Yes. There is no account, no daily cap, no file-size tier and no watermark, because there is no server cost to recover. The site is funded by clearly disclosed partner recommendations on the Partners page, never by metering the tools.
